It is said that when lung cancer was discovered, it was already in the advanced stage. What "distress signals" will be sent out when there is a problem with the lungs? 1, cough
Cough is the most common symptom of respiratory diseases and one of the main manifestations of lung cancer in the early stage. If you often cough in recent days, and the cough symptoms last too long, and there is no obvious improvement after taking the medicine, then you need to be vigilant. It should be noted that if cancer grows on bronchopulmonary tissue, it may also cause irritating cough. This strange cough is like choking rice in the airway, and the body coughs in response to stress.
2. Blood in sputum or coughing up blood
The first symptom of about13 patients is blood in sputum or coughing up blood, mainly because the blood vessels in tumor tissue are very rich, and coughing can lead to tumor tissue rupture and bleeding. Of course, inflammation caused by tumor can also lead to hemoptysis. Hemoptysis caused by lung cancer is often intermittent and persistent, accompanied by blood in sputum. A few patients may have massive hemoptysis due to the rupture of large blood vessels.
3, hoarse voice
In daily life, once lung cancer metastasizes to supraclavicular lymph nodes, it will affect the throat, leading to throat inflammation or swelling, and even hoarseness. Later, with the continuous development of the disease, hoarseness will become more and more serious, and when it is serious, you may be speechless. In addition, when the disease develops rapidly, it is very likely that there will be hemoptysis and dyspnea, so please be vigilant at this time.
4. Chest pain
About half of the patients will have chest pain, and when the tumor site invades the pleura due to growth, there will be irregular dull pain. When the tumor compresses the ribs and spine, it can also cause persistent chest pain. If the tumor compresses the intercostal nerve, the pain site will swim with the nerve. If the tumor invades mediastinal lymph nodes, it can induce deep pain behind the sternum.
5. Sudden fever
At this time, patients with lung cancer often have fever symptoms of unknown causes, and their body temperature is generally around 38℃. If anti-inflammatory treatment is used, the symptoms will be relieved quickly, but if anti-inflammatory treatment is not completely eliminated, the disease will often recur, and then lung cancer patients will have inexplicable chest tightness, pain, shortness of breath and other physical discomfort symptoms.
Step 6 stick fingers
Clubbing finger can't be the only manifestation of lung cancer. In fact, there are many serious chronic lung diseases, clubbing fingers will appear to varying degrees, and lung cancer patients account for about 10%. The so-called clubbing refers to the abnormal proliferation and expansion of the ends of the fingers and toes of the patient, and the nails protrude from the surface of the fingers and look like drumsticks. Clinical data show that lung squamous cell carcinoma is more likely to induce clubbed finger symptoms.
Lung cancer "favors" these five types of people. If you are among them, it is best to have a screening once a year! 1. Long-term smokers
2. People exposed to radiation for a long time
3. People with a history of basic lung disease
4. People with a family history of lung cancer
How to prevent lung cancer in life? 1, quit smoking
During the burning process of cigarettes, more than 3000 kinds of toxic substances will be produced, which will enter the human lungs through the respiratory tract and infringe on lung health. Therefore, smoking is considered to be one of the most important factors leading to lung cancer. To stay away from lung cancer, the first thing to do is to give up smoking.
2. A lung nourishing tea
Lilac rock osmanthus black tea is a dietotherapy prescription recorded in the ancient medical book Biography of Lin Yi. Prepare clove, clove leaf and cinnamon, make clove cinnamon black tea according to the production process of black tea, and boil it in water for about 10 minute. Clove has the functions of clearing away heat and toxic materials, clearing away lung heat and moistening lung, relieving cough and resolving phlegm. Can be used for treating chronic pharyngitis, chronic bronchitis and asthma with good curative effect. Coupled with the functions of relieving cough and resolving phlegm, warming lung and eliminating dampness, the combination of the two can get twice the result with half the effort.
3. Be proactive and exercise more.
People who want to prevent lung cancer should take more active exercise at ordinary times, which can improve heart and lung function. When the heart and internal function are improved, this part of the young state can usually be effectively maintained, and help is needed for the prevention of diseases. Therefore, people who want to reduce the prevalence of lung cancer should delay the aging of the body and promote lung health through reasonable exercise.
4. Go to the hospital regularly. If there are symptoms such as frequent dry cough, persistent cold cough and bloodshot sputum, it is necessary to pay attention to it and go to the hospital for examination in time. These are all early signs of lung cancer. If the smoking index of lung cancer in people over 50 years old is more than 400 (daily smoking index * smoking time), they should go to the hospital regularly for lung CT examination, chest X-ray examination and sputum cytology examination to achieve early detection and early treatment.
First of all, the sentence "It is said that lung cancer was discovered too late" has certain clinical basis. About 70-80% of lung cancer patients are in the middle and late stage of the disease when they are first diagnosed. Therefore, the poor prognosis and relatively short survival period of lung cancer are closely related to its late detection. "Soldiers are expensive at a rapid pace" and the treatment of lung cancer is expensive in early detection, early diagnosis and early treatment! The five-year survival rate of stage I lung cancer is over 90%, while that of stage IV lung cancer is below 10%, and even some patients with multiple distant metastasis die before treatment.
Second, what distress signal will be sent when there is a problem with the lungs?
The lung is the respiratory organ and the place where human blood and oxygen exchange, so the problems in the lung must be "breathing-related symptoms", such as cough, expectoration, dyspnea, chest tightness, chest pain and so on.
1, cough and expectoration. The normal respiratory tract should be "unobstructed", with only gas and no "foreign body". As we all know, lung cancer, also known as bronchial cancer, means that cancer cells originated in the bronchus. Normal people breathe freely and generally do not cough, but lung cancer patients have protective cough and expectoration problems because the mass is larger than the respiratory tract. Irritant cough, dry cough and blood in sputum are common symptoms of lung cancer. Once the above symptoms appear, please seek medical attention and have a chest CT.
2, chest tightness, chest pain. Some friends will say that chest tightness and chest pain are not symptoms of heart disease, acute angina pectoris and myocardial infarction. Why does lung cancer also appear? Tell you, in fact, a considerable number of lung cancer patients see a doctor because they feel chest tightness and occasional pain during this time. Chest tightness can be a lump blocking the bronchus or pleural effusion caused by lung cancer (imagine, the alveoli are in the water, can you not feel chest tightness? )
3, neck or supraclavicular lymph node enlargement. I think this sign is quite common in patients with lung cancer. The specific performance is that you can touch the small bag in the "nest" above the neck or collarbone, and the texture is usually hard. If this happens, please do a color Doppler ultrasound and have a quick look.
Finally, I remind you that once symptoms (signals) appear in the lungs, they are mostly in the middle and late stages, and the treatment effect is very poor at this time. Low-dose chest CT is helpful to find early lung cancer. I recommend you to do this screening!
Lung cancer is one of the most common malignant tumors in China, with a large number of patients and a trend of rejuvenation. Because of the lack of specific manifestations in the early stage of lung cancer, it is easy to be ignored by everyone, which leads to the fact that most patients are in the middle and late stage once diagnosed, and the prognosis is not good. Everyone should take preventive measures, early detection and timely treatment, which is very important to improve the prognosis.
Common clinical symptoms of lung cancer mainly include:
1, Cough: About half of lung cancer patients have cough symptoms, mostly irritating dry cough;
2, hemoptysis: mostly manifested as blood or hemoptysis in sputum, but large hemoptysis is rare;
3. Dyspnea: Decreased alveolar area or enlarged and compressed lymph nodes caused by tumor spread, atelectasis or obstructive pneumonia;
4, fever: caused by tumor necrosis or secondary pneumonia;
5, wheezing: it is caused by the tumor growing in the big airway;
6, chest pain: caused by cancer invading the pleura, when bone metastasis occurs, the pain is often severe;
7. Complications and structural symptoms caused by primary tumor invading adjacent organs: it can be manifested as pleural effusion, hoarseness, phrenic nerve paralysis, dysphagia, pericardial effusion, superior vena cava obstruction syndrome, etc.
8. Symptoms caused by distant metastasis of tumor: ① Central nervous system metastasis, headache, nausea and vomiting. ② Bone metastasis with severe progressive pain.
Everyone must pay enough attention to not smoking or quitting smoking, avoid asbestos and masons, and actively treat lung diseases. At the same time, it is very important for prognosis to pay attention to regular screening, early detection and timely treatment.
For cancer, doctors have been saying, don't wait until the body has symptoms, and then check it out, because it may have reached the middle and late stage of cancer and lost the best treatment period, and we should take the initiative to do a good health check-up and do a good job in cancer prevention. This is what we need to do most.
For lung cancer, it is one of the most common malignant tumors in our daily life. Due to the lack of specific manifestations in the early stage of lung cancer and the complex biological characteristics of lung cancer, 80% of lung cancer patients were diagnosed as advanced.
However, we are not saying that there are no symptoms when lung cancer occurs, but that there are no specific symptoms when lung cancer occurs, especially in the early stage. Even if there are symptoms sometimes, they will not be noticed, and they will not be checked in time. Waiting until the symptoms are obvious will delay the illness. In fact, this is the main reason for the late detection of lung cancer.
So in this respect, if you feel unwell, you should go to the hospital in time and cooperate with the doctor. However, at present, due to the importance attached to their own health, economic conditions, concepts and other factors, patients have symptoms of physical discomfort and are willing to delay medical treatment. In fact, it is not only lung cancer, but many diseases are delayed because they are not delayed.
However, when there are obvious symptoms of lung cancer, we should try to find the clues brought by lung cancer as soon as possible, and remind everyone to see a doctor in time through these symptoms, find the problem as soon as possible and treat it as soon as possible. This is also very important to us.
Lung cancer most commonly occurs in bronchial mucosa epithelium, also known as bronchial cancer. However, those confined to the basement membrane are called carcinoma in situ, and then gradually grow to the bronchial cavity or adjacent lung tissue, which can be spread by lymphatic blood or bronchial metastasis.
However, our bronchial mucosa epithelium has no nerve distribution, so there are few or no early symptoms. When lung cancer invades the submucosal muscle layer, it may be felt, but if it protrudes from the trachea or invades the surrounding tissues, it will show obvious symptoms.
The first is a persistent cough.
In particular, there is no obvious cause of cough, mainly dry cough, sometimes irritating dry cough. Symptoms usually last for more than two weeks, and there is no obvious improvement through drug treatment. You need to be vigilant and should see a doctor for examination.
Second, coughing is accompanied by bloodshot blood.
It may not matter if you cough occasionally, but if you cough repeatedly with bloodshot blood, you need to be alert to cancer.
The third is a dull pain in the chest and back.
The pain in the early stage of lung cancer is not obvious, but it can be manifested as dull pain, faint discomfort in the chest, recurrent symptoms, and sometimes back pain.
Fourth, fever for unknown reasons.
Because tumors often have obstructive pulmonary lobes after blocking bronchi, the degree varies, ranging from low fever to high fever, especially complicated infection, which is more prone to fever. It can be improved after medication, but it happens repeatedly.
Fifth, joint symptoms.
Such symptoms are more common. Because lung cancer cells can produce some special endocrine hormones (heterologous sex hormones), antigens and enzymes, these substances act on bones and joints, causing swelling and pain of bones and joints, and the ends of fingers and toes often expand into clubbed fingers, which is more easily overlooked.
Sixth, anorexia and fatigue.
This is mostly the manifestation of cachexia in the late stage of lung cancer, and it is a symptom caused by high consumption of lung cancer. However, fatigue may occur in the early stage of lung cancer, which is also related to some substances secreted by the tumor.
Seventh, late symptoms.
Therefore, if the above symptoms appear, chest X-ray, sputum cytology, fiberoptic bronchoscopy, lung CT, lung magnetic resonance vibration, lung puncture and other examinations should be actively carried out to make a clear diagnosis.
Smoking room is one of the most important factors of lung cancer, so smokers should actively quit smoking and avoid colleagues smoking second-hand smoke at work. After quitting smoking, the risk of lung cancer will decrease year by year as abnormal cells in the lungs are gradually replaced by normal cells.
Second, strengthen labor protection.
Many workers are exposed to carcinogenic chemicals, such as radioactive substances and their derivatives, carcinogenic hydrocarbons, etc., which are easy to induce cancer attacks. Therefore, there is no need to do personal protection at work, improve the ventilation environment in the workplace, reduce the concentration of harmful substances in the air, and reduce contact with carcinogenic chemicals and physical stimuli.
Third, develop correct eating habits.
Eat less fried and barbecued foods, especially reduce the inferior oil that is repeatedly heated at high temperature, because the concentration of harmful gases in the lampblack after repeated high temperature heating is very high. Eat a regular diet, a balanced diet, and eat more vegetables, fungi and beans.
Fourth, strengthen exercise, live a regular life and enhance immunity.
Improve physical resistance through active physical exercise and regular living habits.
Fifth, actively treat chronic lung diseases.
Especially chronic bronchitis, chronic obstructive pulmonary disease and tuberculosis.
Sixth, regular physical examination, especially for occupational contacts and people in areas with high incidence of lung cancer.
Be sure to have regular physical examinations, especially for smokers and people who are exposed to chemicals caused by lung occupation. It is best to have a physical examination once a year.
To sum up, the early symptoms of lung cancer are rare or atypical, and it is most important to do regular physical examination and lung cancer prevention every day.
Many people say that lung cancer was discovered late, which makes sense. When many lung cancer patients find lung cancer clinically, many of them are already in the advanced stage. Why is this happening? In fact, this has a lot to do with the concealment of lung cancer and personal negligence, because when the lung becomes cancerous, the body will send out some "distress signals." But many people don't pay attention to these "distress signals" or think that they are caused by other diseases, and few people think of lung cancer.
Then, what "distress signals" will be sent out when there is a lung problem? There are mainly the following types: 1. Keep coughing.
Our lungs are very fragile and sensitive. As long as lung tissue is damaged, such as inflammation and malignant transformation of lung tissue, cough will occur. But if the lung tissue is seriously damaged, such as cancer, then the cough is persistent, that is, coughing day and night, coughing constantly. If this happens, we should pay attention to it. Don't think it's just a small cold or bronchitis, pneumonia, etc. Be sure to go to the hospital for related tests.
2. Blood in sputum or coughing up blood
When lung tissue is damaged, especially when cancer occurs, because of the abnormal proliferation of cancer cells, it will continue to invade nearby normal cells and damage the tissue. In addition, both cancer cells and normal cells will die during the battle, resulting in inflammation and bleeding. After continuous coughing, you can see blood in the sputum or coughing up blood.
3. Chest tightness and chest pain: When lung tissue is damaged, it will naturally affect the normal gas exchange in the lungs. If alveoli can't exchange gas normally, it will cause insufficient oxygen, which will easily make people feel chest tightness; In addition, due to the damage of lung tissue, cancer cells proliferate and invade the normal tissues nearby, thus causing chest pain.
4. Back pain
Back pain is also an obvious manifestation of lung tissue injury, which belongs to a kind of procrastination, because the growth of tumor invades the pleura, causing irregular dull pain. Especially when the tumor compresses the ribs and spine, it will cause persistent chest pain, involving the nerves in the back, and it will also cause back pain.
5. clubbing fingers appear
That is, the knuckles thicken and swell. This is because the lung tissue is seriously damaged, which affects the gas exchange in the lung, thus leading to the state of hypoxia and ischemia at the fingertip, which makes the fingertip tissue proliferate and thicken, resulting in abnormal expansion and uplift. If clubbed fingers appear, it means that lung tissue damage has not happened in a day or two, but for a long time. At this time, it is necessary to go to the hospital in time to do relevant examinations and clarify the cause.
Of course, the above symptoms are probably distress signals when lung tissue is damaged, but it would be ridiculous and scary to judge the existence of lung cancer only by these symptoms. Therefore, even if the above symptoms appear, we still need to go to the hospital for related examinations, such as lung function examination, lung CT, tumor markers examination and so on. Even lung biopsy is needed to make clear the cause and receive effective treatment. In addition, if the above symptoms appear, we should also pay attention to them. After all, early detection and early treatment can have a better therapeutic effect and improve the survival time of lung cancer.
Especially for some people who smoke for a long time or deal with dust and toxic gases for a long time, we must pay special attention. If the lungs feel uncomfortable, seek medical advice in time to avoid lung cancer. If it is found in the late stage of lung cancer, it is really late and I regret it. Of course, for smokers, quitting smoking can reduce the incidence of lung cancer.
Message from the author: I am very happy to give you the knowledge of popular science and health. I am a left-handed doctor. I give you the knowledge of popular science and medicine in simple language every day. Codewords are not easy. If you like my article, please give me a compliment! If you have any questions, you can leave a message in the comments section. Welcome to pay attention and forward. Thank you for your support! Frequent dry cough, boils on the nose, sore throat and sores on the back all need timely treatment.
We are all familiar with lung cancer, which is a common malignant tumor. There are some symptoms in the early stage of lung cancer. Early detection and early treatment are good for your health. Pay special attention to your immunity at ordinary times. Only when immunity is enhanced can we resist the harassment of diseases and cancer. A product containing ginsenoside rh2, rg3, Ganoderma lucidum polysaccharide and salidroside, such as Anpu Capsule, can be tried, which is very helpful to improve immunity, and its content of rh2 and rg3 is still very high, which can be found in a certain east and cat search. So what are the early symptoms of lung cancer? How to protect the lungs at ordinary times? Let's take a look together.
Early symptoms of lung cancer
ear-piercing
Hoarseness is an important feature of early lung cancer. It can also occur in diseases such as pharyngolaryngitis, cold and acute bronchitis, and it can also occur after pharyngeal surgery.
But this kind of hoarseness can generally be cured by symptomatic treatment or rest. The hoarseness caused by lung cancer, thyroid cancer and laryngeal cancer is absolutely different from the above hoarseness, especially the hoarseness caused by lung cancer.
Other early symptoms of lung pain, such as cough, chest pain and hemoptysis, lack characteristics, while hoarseness has certain specificity. According to statistics, about 20%-30% of lung cancer patients may have hoarseness at different stages of the disease, including the early stage, among which central lung cancer can reach as high as 40%.
Lung cancer causes hoarseness, mainly because the tumor compresses the nerves that control the vocal cords. This kind of hoarseness occurs suddenly and develops rapidly, and many patients will be accompanied by chest pain symptoms.
themogenesis
Central lung cancer grows in the bronchus, and when the lumen is semi-blocked or completely blocked, it can produce obstructive pneumonia. The fever is generally around 38, and it is easy to reduce the fever after anti-inflammatory treatment. However, if the obstructive lesions are not removed, pneumonia will soon reappear and form repeated pneumonia.
asymptomatic
About13 of lung cancer patients have no obvious early symptoms, and their lesions can only be found early through regular examination.
haemoptysis
This is special in early lung cancer cases, such as central lung cancer. Hemoptysis often occurs in the early and middle stages of the course of the disease, with little blood, bright red or mixed with foam. The reason for this phenomenon is that the tumor surface is rich in blood vessels. Cough damages the surface and causes blood vessels to rupture. If you cough up more blood occasionally, it often appears repeatedly or only lasts for a long time.
cough
Different parts of lung cancer have different functional damage. So, the symptoms are different. Generally, most tumors grow on the big bronchus, which is very irritating, so there will be a cough.
After secondary infection, the quality of sputum also changes. Patients with chronic cough should be vigilant if they find that the cough is different from usual. Patients with high-risk age should see a doctor as soon as possible when their cough is ineffective or lasts for a long time after treatment. Patients with hemoptysis should be diagnosed early.
How to protect the lungs
Replenishing water and benefiting lung
Now the climate is relatively dry, and you should drink at least 500 ml more water every day than in other seasons to maintain the normal humidity of the lungs and respiratory tract. In addition, you should take a bath often, because fur is the barrier of the lungs. Autumn dryness is the easiest to hurt fur, which in turn hurts the lungs. Bathing is beneficial to blood circulation and can make the lungs and skin unobstructed.
Nourish the lung
Three meals a day should be based on nourishing yin and promoting fluid production, such as sesame seeds, honey, pears, lotus seeds, tremella, grapes, radishes, vegetables and other soft foods. Eat less spicy products and take supplements when necessary, but make up, not make up.
Lung moistening medicine
There are a lot of dry pathogens, and old diseases of human body are easy to recur, the most common one is cough and asthma. At this time, taking some Chinese medicines in a targeted manner has a certain preventive effect.
Laughter is always open, dispersing lung meridian.
A heartfelt smile can spread lung qi all over the body and fully relax the muscles of the face, chest and limbs. In addition, the distribution of lung qi can also calm liver qi, thus maintaining emotional stability.
Exercise enhances lung function.
Physical exercise is an important way to strengthen the lungs. Walking, gymnastics, qigong, etc. Can achieve the role of strengthening the lungs, of which the role of qigong is particularly obvious.
Conclusion: Through the above introduction, I believe everyone has a general understanding of the early symptoms of lung cancer. In addition, the article also introduces some methods to protect the lungs, hoping to help everyone. Lung cancer can not be ignored, so we should pay more attention to prevention at ordinary times.
Lung cancer is a malignant tumor with rising incidence in recent years, which has attracted great attention. In fact, lung cancer is coming, and the body will have these "distress signals", so we must pay attention.
Long-term shortness of breath usually occurs after exercise. If shortness of breath occurs suddenly, it may be because lung cancer tissue blocks the respiratory tract or cancer cells invade some organs of the body, resulting in shortness of breath. Stay alert.
Hoarse Some lung cancer patients have hoarseness, usually accompanied by cough. If it is not because of a cold or bronchial problems, it may be that the tumor compresses the trachea and vocal tract, leading to airway obstruction.
Frequent chest pain chest pain is not necessarily caused by lung cancer, but if there is persistent chest pain, it should be taken seriously.
In the early stage of joint disease lung cancer, there will be clenched fingers, enlarged knuckles, and sometimes gray nails and pain.
Long-term low fever in the body may be caused by necrosis and infection of lung cancer cells.
Frequent and severe cough If you have a fever with severe cough, you must pay attention to it. This happens to some patients with lung cancer.
Suddenly lose weight If you are a long-term smoker, you suddenly find yourself losing a lot of weight recently, and your normal diet is still the same every day. You must be vigilant, especially this kind of weight loss for no reason.
In the early stage of hemoptysis, lung cancer patients will have hemoptysis. Generally, there is bloodshot phlegm, and the blood volume is very small, so we must not underestimate it.
F We must not neglect these situations, especially those who have a long history of smoking. We must pay attention to physical examination and rule out the risk of cancer.
Lung cancer is a high incidence of respiratory tract malignant tumor. With the decline of air quality and other factors, the incidence and mortality of lung cancer are on the rise.
The prognosis of lung cancer is closely related to its detection. When lung cancer occurs, the human body may have the following symptoms.
What are the manifestations of people when lung cancer occurs? 1, cough.
With the growth of tumor tissue in the lungs, the stimulation to the lungs and respiratory tract becomes more and more intense, and people will have symptoms of irritating cough, which will not get better after drug treatment.
2, low fever
Many cancer patients will have low fever symptoms at the initial stage of diagnosis, which is the result of the struggle between their own immune system and tumor tissue. If the persistent low fever does not improve after targeted treatment, we should be alert to the occurrence of cancer.
3, chest pain
Lung tumor can compress peripheral nerve block, leading to chest pain, dull pain, pain and other symptoms. When the respiratory frequency increases or the respiratory depth increases, the symptoms of chest pain can be aggravated. When pleural metastasis occurs in lung tumor, it can lead to the aggravation of chest pain.
4. Hemoptysis
Lung tumor can lead to inflammatory reaction in lung tissue, which in turn leads to tissue cell necrosis and capillary damage, leading to blood in sputum when coughing.
If there are repeated bloodshot sputum, and it has not improved after routine treatment, we should be alert to whether it is lung cancer.
The early symptoms of lung cancer vary greatly according to the types of cancer, so it is suggested that people who smoke for a long time, who are exposed to second-hand smoke for a long time, who work under lampblack for a long time, who are exposed to asbestos, wooden boards and other employees, and who are exposed to radiation for a long time should be screened for lung cancer in time.
Related screening items include chest radiograph, computed tomography, bronchoscopy, mediastinoscopy, thoracoscopy and other internal diameter examinations, which can directly see the situation of lung tissue.
A good life comes from a healthy beginning, a healthy beginning and professional media of health science!
