The occurrence of cancer is determined by internal and external factors. Cancer will only occur if certain internal factors are combined with external carcinogenic factors such as radiation and smoking. Oncogenes related to lung cancer include: -, -(small cell lung cancer), protein, etc. Professor Wang Jianzhang said that if a parent has this type of colon cancer, there is a % chance that their children will also get the same type of cancer. Pay attention to the appearance of extrapulmonary symptoms such as clubbing, anemia or elevated blood cells, hypertrophic osteoarthropathy, and recent signs of endocrine disorders. Retinoblastoma is caused by an abnormal gene. % of people with the abnormal gene will develop this type of cancer. Professor Wang Jianzhang said that the cancer most closely related to genetics is childhood retinoblastoma. Its symptoms are: children suddenly lose sight when they are old. Chest X-ray and other examinations such as Tarceva in India are of great value in the early diagnosis of lung cancer. But environmental factors are also important in promoting this type of colon cancer.
Even people with familial aggregation are unlikely to get cancer if they are not exposed to carcinogens. This is a type of multiple, familial polyposis that grows in the intestines, especially the large intestine, and is more likely to develop into colon cancer. In addition, Professor Wang Jianzhang said that the hereditary nature of bilateral breast cancer is relatively obvious. It is reported that the familial inheritance of cancer is caused by chromosomal aberrations. Educate the public to pay attention to the precancerous lesions and clinical manifestations of lung cancer so that they can seek medical treatment promptly.
The hereditary nature of gastric cancer and esophageal cancer is not very obvious. Some people have also experienced family aggregation. Some people think that this is caused by genetic factors, mainly changes in chromosomes and genes. However, the causes of breast cancer cannot be attributed to genetics because the causes of breast cancer are multifactorial, including too much fat in the diet, increasing age, obesity, not breastfeeding, being single, etc. Carry out lung cancer screening to detect small, localized and non-metastatic tumor lesions as early as possible. This is a clear example of a congenital tumor.
The early application of monoclonal antibodies in the diagnosis of lung cancer is beneficial to the localization diagnosis of lung tumors. Women whose mothers or sisters have had breast cancer in their families have a higher chance of developing breast cancer than other women. Although some examination methods are of certain significance for the early diagnosis of lung cancer, those with specificity should pay attention to their comprehensive application in the near future. Such as: serum electrophoresis factors, serum sialic acid determination, neural enolase, mucin antigen and nerve cell adhesion molecules, etc.
Conduct tumor marker and other examinations on suspicious objects.
Pay attention to the prevention of precancerous lesions and the treatment of Tarceva. Pay attention to the prevention of some carcinogenic and cancer-promoting factors. Perform repeated sputum exfoliated cytology examinations on suspicious subjects. Improve the diagnosis level of lung cancer in grassroots and general hospitals and establish a referral system and awareness to reduce misdiagnosis. Hospitals where conditions permit should conduct tumor-related oncogene testing on suspicious subjects. Attention should be paid to patients suffering from various chronic pneumonia and tuberculosis. Each cell in the normal human body has a chromosome. Various carcinogens can cause chromosomal aberrations, making the chromosomes different in number and shape from normal cells. Such chromosomal aberrations are sometimes passed on to future generations, making the next generation more likely to develop cancer. Fiberoptic bronchoscopy and histocytology examination are meaningful for central lung cancer. If some patients have breast cancer in two or three generations of their family, it is necessary to consider whether it is hereditary.
