Why can't cancer be cured?
Cancer, also known as malignant tumor in medicine and rock in traditional Chinese medicine, is a disease caused by abnormal mechanisms that control cell growth and proliferation. In addition to uncontrolled growth, cancer cells will locally invade the surrounding normal tissues and even transfer to other parts of the body through the circulatory system or lymphatic system.
According to experts, if cancer patients can find cancer in the early stage of cancer, seek medical treatment in time, supplemented by air negative ion natural therapy, cancer is completely possible to be cured. Because cancer cells have the characteristics of infinite and endless proliferation, nutrients in patients are consumed in large quantities; Cancer cells release a variety of toxins, causing a series of symptoms; Cancer cells can also spread to all parts of the body for growth and reproduction, leading to emaciation, weakness, anemia, loss of appetite, fever and serious organ function damage.
In contrast, there are benign tumors, which are easy to be removed, generally do not metastasize or recur, and only have squeezing and blocking effects on organs and tissues. However, cancer (malignant tumor) can also destroy the structure and function of tissues and organs, causing necrosis, bleeding and infection, and patients eventually die of organ failure. Even if it is basically cured temporarily, it may recur because of the remaining undetectable cancer cells.
So even authoritative experts can't guarantee a cure. The standard of medical cure is different. Cure generally means that cancer cells cannot be detected at present, and they will be cured if they do not recur within 5 years. However, due to various factors, there is no guarantee that it will recur in the future. Moreover, different cancers have different cure standards.
Will cancer definitely kill you?
The high incidence and mortality of cancer make us have to talk about "cancer" in our lives. Many people learn that they have cancer, which is like being sentenced to death, and it is "executed immediately".
But in fact, there are some misunderstandings in this understanding. Most cancers are indeed death sentences, but they can be "suspended" and the time that can be suspended varies greatly. In other words, not all cancers develop very rapidly. Therefore, after learning that you have cancer, you should actually understand cancer scientifically and treat the disease with a correct attitude while being afraid and worried. Next, I will show you the prognosis of different cancers.
1. What is the "five-year survival rate" of cancer?
When diagnosed with cancer, I believe the first question that many people think of is: "How long can I live?" In other words, they want to know the prognosis of their disease and whether this cancer is easy to treat.
Indeed, doctors do not have the ability to predict the future, but they can make corresponding estimates according to the situation of cancer patients in similar situations, and this estimate, in medical terms, is the "five-year survival rate"-referring to the proportion of patients with malignant tumors who can survive for more than five years after various comprehensive treatments.
For example, the overall 5-year survival rate of bladder cancer is 67.3%, which means that among 100 patients with bladder cancer, 67 patients can survive for 5 years or more after active treatment, and the remaining 33 patients may die within 5 years. The 5-year survival rate of liver cancer is 10. 1%, which means that only 10 patients can survive for more than 5 years after treatment. The different "five-year survival rate" of these two tumors reflects that the "fierceness" of liver cancer is far greater than that of bladder cancer.
Then why use the "five-year survival rate" as an indicator to reflect the prognosis of cancer?
Because in a large number of clinical investigations, it is found that some patients may have metastasis and recurrence after radical surgery, mostly within three years after surgery, accounting for about 80%; A few cases occurred 3 ~ 5 years after radical operation, accounting for about 10%. However, if cancer patients can survive for five years or longer and the tumor does not recur, the risk of recurrence after five years is greatly reduced, so the "five-year survival rate" is usually used to reflect the prognosis of various cancers.
Second, what is the use of "five-year survival rate"?
1 and "five-year survival rate" are helpful to predict the survival probability.
Patients can understand the general possibility that they can survive for more than 5 years after cancer through the experiences of these patients with the same cancer. In addition, doctors will also combine other factors of patients (such as age and health status) to help fully understand the seriousness of the disease.
2. "Five-year survival rate" is helpful to determine the treatment plan.
The five-year survival rate of the same cancer is different according to different treatment schemes. Patients can weigh the advantages and disadvantages according to the five-year survival rate of other patients under different treatment schemes, and decide the treatment scheme together with doctors.
3. What have I not told you about the "five-year survival rate"?
1, the "five-year survival rate" of cancer is not a fixed data.
The five-year survival rate is based on the overall data obtained by studying hundreds of people with the same cancer. This is a statistical result and cannot provide the probability of cure, remission or recurrence of a specific individual. If you want to break it down, everyone's situation is actually different.
The five-year survival rate of tumors is usually closely related to the following factors:
Tumor staging: The overall five-year survival rate of cervical cancer patients is 55%, and the stages I, II, III and IV are 85%, 60%, 30% and 10% respectively.
Treatment: The five-year survival rate of open surgery for early thymic tumors was 83%, and that of thoracoscopic adenoidectomy was 92%.
Age of patients: The five-year survival rate of breast cancer patients under 40 years old is 78.8%, and that of patients over 40 years old is only 44.4%.
Gender: The overall five-year survival rate of lung cancer is 16. 1%, but specifically, it is 15.4% for men and 17.4% for women.
Geographical factors: the five-year survival rate of urban patients is 19.5%, and that of rural patients is 1 1.2%.
2. "Five-year survival rate" does not provide the latest medical data.
Patients who participated in the "five-year survival rate" statistics were diagnosed with cancer at the latest five years ago, so the effect and prognosis of the latest treatment methods cannot be judged by the five-year survival rate.
For example, before the 1970s, there was no CT technology. When lung cancer is found, it is basically advanced, and the five-year survival rate is extremely low. Using CT technology, lung cancer can be found at an early stage and treated actively. After several years of statistical investigation, the five-year survival rate of lung cancer will be improved.
3. "Five-year survival rate" does not tell patients which treatment to choose.
For some patients, they may choose a treatment scheme that can prolong their life to the maximum extent, but this scheme may cost them some money, such as high medical expenses and great side effects. Other patients may consider these factors comprehensively and choose other conservative treatment schemes to avoid the pain caused by more treatment in the last stage of life. Therefore, it is up to patients and doctors to decide which treatment to choose.
4. What is the five-year survival rate of various cancers?
The National Cancer Research Center published a national survey in the International Journal of Cancer in 20 14. From 2003 to 2005, there were 2 1 38852 cancer patients diagnosed in hospitals in China, and the overall five-year survival rate was 30.9%. Compared with the overall five-year survival rate of cancer patients in the United States, the specific data of the overall five-year survival rate of various cancers in China are as follows (horizontal map, check the detailed data through mobile phone):
What kind of cancer can be cured?
1. colorectal cancer: 80% of early colorectal cancer can be cured.
Bloggers see that statistics show that with the improvement of economic development level, the incidence of colorectal cancer is on the rise. Compared with gastric cancer, colorectal cancer has the trend of "eliminating one and increasing one". At one time, China was a country with stomach trouble, which was the product of the era of material scarcity. Now, the reality brought by the material-rich era is that the incidence of gastric cancer has decreased and the incidence of colorectal cancer has increased. Experts found that colorectal cancer is a disease closely related to diet. High-fat and low-fiber diet combined with sedentary and less exercise is the biggest pathogenic factor. As a malignant tumor, the treatment of colorectal cancer is still a trilogy of surgery, medicine and radiotherapy. For early detection of intestinal cancer, the cure rate can be as high as over 80%. And the surgical trauma is not big. For tumors found very early, laparoscopic surgery can be completed.
2. Skin cancer: The incidence of cancer is high in summer.
Skin cancer is a common malignant tumor among white people, but its incidence has increased in China in recent years. Fortunately, skin cancer is a kind of malignant tumor that is easy to cure, provided that it is found and treated early. Experts found that the occurrence of skin cancer is related to the acidic environment. Acidified body fluid environment is fertile ground for normal cell canceration. Adjusting the acid-base balance of body fluids can effectively prevent skin cancer.
3. Gastric cancer: the transition from infectious disease to chronic disease
China has always been a high incidence area of gastric cancer. The proportion of young people suffering from gastric cancer is getting higher and higher. 15% of patients are young people under 40 years old. The cure rate of gastric cancer is also related to whether it is found early. If found early and treated early, gastric cancer is also a disease with a cure rate of over 60%. WH0 survey found that 50% of gastric cancer is related to Helicobacter pylori infection. In China, 60% of patients with gastric diseases have the problem of Helicobacter pylori infection. Some experts even call gastric cancer an "infectious disease", because Helicobacter pylori infection is related to China people's habit of "eating". Experts suggest that diners should develop the good habit of sharing meals or using public chopsticks.
4. Lung cancer: Low-dose spiral CT is helpful for early detection.
Lung cancer is the "deadliest tumor" because it is usually difficult to find it early. Once there are obvious symptoms such as irritating cough, bloody sputum or hemoptysis, chest pain, shortness of breath, etc., it often belongs to the middle and late stage. In recent years, medical scientists have been looking for effective methods to treat lung cancer. With the development of medical imaging technology, low-dose spiral CT scanning of chest is helpful to find early lung cancer in time. If early lung cancer is treated by surgery in time, the 5-year and 10-year survival rates can reach 85% and more than 50%.
5. Malignant lymphoma: 50% of early lymphoma can be cured.
Malignant lymphoma was once considered to be incurable, but with the advent of targeted drugs in recent years, the 5-year survival rate of malignant lymphoma has exceeded 50%. The cure rate of early Hodgkin lymphoma is over 80%. A large number of clinical trials have confirmed that after immunotherapy, 50% of patients with early lymphoma can be cured, and half of them can still live a healthy life after 5 years of illness.
6. Cervical cancer: cancer that can be prevented by vaccination.
Cervical cancer is the easiest cancer to cure. If it can be found early, the cure rate can almost reach 100%. And the first cancer vaccine successfully developed in the world is the cervical cancer vaccine. The high cure rate of cervical cancer undoubtedly makes human beings full of greater confidence in the cause of defeating cancer.
7. Breast cancer: the most suitable cancer for personalized treatment.
Breast cancer is a kind of cancer that scares all women. It not only endangers life, but also makes women face the problem of incomplete gender characteristics. It is a malignant tumor with great physical and psychological lethality. But now breast cancer has become one of the cancers with the highest cure rate. If detected and treated early, 70% of women can still recover. Moreover, the current level of medical development has achieved breast conservation to the greatest extent, minimizing the pain of surgery and the harm to the body. The above is the introduction of 7 kinds of cancer that can be cured. In fact, cancer is not terrible. If everyone can see a doctor as soon as possible after the early symptoms of cancer appear, it can still be treated.
