What kind of cancer begins with blurred vision? Many people have bad eyes. Cancer is a disease with a low cure rate. Blurred vision appears in the late stage of cancer, probably because cancer cells have metastasized to the brain. Let's see what kind of cancer begins with blurred vision.
What kind of cancer begins with blurred vision? 1 Lung cancer is the most common primary lung malignant tumor. The vast majority of lung cancer originated from bronchial mucosa epithelium, so it is also called bronchial lung cancer. The symptoms of lung cancer are different at each stage. Early lung cancer generally does not produce symptoms, so it is also called asymptomatic period, as short as several months.
Just a few years, depending on the person. Some early symptoms of lung cancer are just common respiratory symptoms such as dry cough, chest pain, low fever and hemoptysis. These symptoms are confused with colds, bronchitis, pneumonia and other diseases, which are difficult to find clinically.
Many people lost their lives because of lung cancer, which is worthy of the title of one of the killers of mankind. Lung cancer is divided into several different periods, and the symptoms of each period are different. According to these different symptoms, doctors adopt different treatment methods.
Basically, the sooner lung cancer is treated, the better. Next, let's look at the early symptoms of lung cancer. Therefore, doctors suggest that patients should pay attention to similar symptoms once they appear, and suggest that high-risk groups have regular physical examinations to achieve early detection and early treatment.
Detailed explanation of early symptoms of lung cancer
1, persistent headache
Early lung cancer is prone to distant metastasis, so the symptoms related to distant metastasis are often the early symptoms of lung cancer found by doctors or patients. If the lesion metastasizes to the brain, it may lead to persistent headache and blurred vision. Continued development may lead to confusion and even epilepsy. There is no obvious difference between this kind of headache and ordinary tension headache, so it is easy to be ignored by people.
2, blurred vision
In the early symptoms of lung cancer, blurred vision is mainly manifested as difficulty in reading newspapers or watching TV. Because most lung cancer patients are elderly people, they often mistakenly think that they just need to change their glasses, but the key lies in the change of vision nature. At first, it was very sensitive to changes in consciousness and vision.
3, shoulder, back, chest, arm pain
Lung tumors may compress nerves, causing pain in patients' shoulders, chest, back or arms-symptoms that may even appear before coughing and shortness of breath. If there are pain symptoms in these parts without primary injury, especially cough and aggravated breathing, you need to pay close attention. Up to 50% of lung cancer patients have chest pain or shoulder pain at the time of diagnosis.
4, long-term cough
Many patients have chronic cough symptoms, but this symptom is often easily ignored by both doctors and patients, or attributed to other reasons. Especially in the case of poor air quality in China, cough symptoms are not very common.
Easily missed. If the patient's cough lasts for more than two or three weeks, it must be taken seriously. In addition to the differential diagnosis with respiratory allergy and respiratory infection, patients with asthma, chronic obstructive pulmonary disease (COPD), allergy or gastroesophageal reflux have cough symptoms due to their primary diseases, so they need to be carefully differentiated when making diagnosis.
5, short of breath when acting
As another early symptom of lung cancer, it is easy to think that this symptom is caused by old age, poor health or obesity. If patients feel short of breath in daily activities and have no cardiovascular disease, they need to pay attention to the screening of lung cancer.
There are many early symptoms of lung cancer. If the patient feels wrong, on the one hand, he can conduct a self-test and on the other hand, he should go to the hospital for examination and treatment. Early lung cancer is not an incurable disease, so don't have too much psychological burden. Keeping an optimistic mood is a good way to treat lung cancer.
What cancer begins with blurred vision? What are the characteristics of eyes related to cancer invasion?
1, sclera yellow
It is found that the eyes and sclera are yellow, which may be caused by severe liver disease. When liver cancer attacks, many people have obvious signs of jaundice. When bilirubin level rises, the eyes will have obvious yellowing performance, and sclera yellowing can be noticed.
In addition, pancreatic cancer, the king of cancer, can also cause jaundice in the process of affecting health. Due to the disease, the lower end of the common bile duct will be invaded. After obvious signs of jaundice, liver disease may occur, and even the sclera of the eye will turn yellow. These are common signs of disease. If the eyes have special manifestations and the whites of the eyes are obviously yellow, it is best to check them in time to determine whether they are related to the canceration of the liver or pancreas.
2. Eye swelling
Whether there is a disease can be judged by the changes in the eyes. Many people will have swollen eyelids after the formation of cancer. If the eyelid is found to be swollen for a long time, or the eyelid has skin lesions, it may be a signal of cancer.
Many people will cause eyelid swelling in the process of meibomian adenocarcinoma affecting health. Meibomian adenocarcinoma is a malignant tumor that occurs in the eye. Although there are no obvious symptoms at the initial stage of the disease, a lump may form locally. It is best to see a doctor in time to prevent the deterioration of eye tumors.
3, blurred vision
Poor eyesight is related to cancer. Some types of cancer will lead to vision loss, even visual field defect and blindness during development, which is a signal of tumors, especially brain malignant tumors, and may compress nerves and lead to vision loss.
If this happens, accompanied by headache and nausea, it is best to go to the hospital at the first time to check whether there is tumor formation in the brain, and then take reasonable measures to improve it, otherwise the eyes will be obviously implicated.
What cancer begins with blurred vision? 3. Eight symptoms of blurred vision.
First, eye diseases
1, ametropia: including myopia, hyperopia and astigmatism, and symptoms such as blurred vision and decreased vision may appear after illness;
2, cataract: more common in the elderly, patients may have symptoms of blurred vision due to elevated intraocular pressure and cloudy deformation of intraocular lens. With the aggravation of the disease, the visual field will have a sense of occlusion;
3. Glaucoma: For glaucoma patients, there is usually no discomfort at the initial stage of illness. With the change of illness, there will be blurred vision, headache, eye swelling, nausea and other discomfort;
4, retinopathy: affected by many factors, such as congenital eye diseases, acquired chronic diseases such as hypertension, eye trauma and so on. As a result, the light cannot normally illuminate the retina, which may lead to blurred vision.
Second, brain diseases.
1, cerebral hemorrhage: more common in patients with acute onset, sudden symptoms such as weakness of limbs, eye deviation, drooling, blurred vision, nausea and vomiting;
2. Others: For example, brain occupying lesions may oppress the optic nerve in the brain, leading to blurred vision. Most patients are accompanied by symptoms such as drowsiness and headache.
Third, systemic diseases.
1. Hypertension emergency: It is more common in patients whose blood pressure rises in a short time, which is greater than 180/ 120mmHg. In addition to blurred vision, there are obvious symptoms such as headache, dizziness, chest tightness and dyspnea, and some patients may have symptoms such as visual impairment and abdominal pain.
2. Diabetes: Poor blood sugar control or diabetic retinopathy may cause blurred vision, usually accompanied by skin infections, vision changes and other symptoms.
Therefore, for patients with sudden blurred vision, it is recommended to go to the hospital for detailed examination in order to make a clear diagnosis and symptomatic treatment in time. Patients with a medical history should be reviewed regularly to be alert to changes in their condition.
