At present, with the extension of human natural life span, the deterioration of environment, the prevalence of cancerous lifestyle and the increase of social competition pressure, the incidence of malignant tumor continues to rise, and malignant tumor, which was unfamiliar 20 years ago, has now become a topic of concern for everyone, and even everyone is at risk, which has become the biggest problem troubling people’s health. How to objectively view the development of malignant tumor and scientifically respond to the high incidence of malignant tumor? The author combines long-term clinical research and international progress of malignant tumor research to discuss some personal views. Malignant tumors are closely related to the aging of the body, and systematic routine physical examination should be started immediately around 40. According to the latest data on the incidence of malignant tumors in the United States and urban and rural areas of China, the overall incidence of malignant tumors starts to rise significantly around 40, especially for common solid tumors such as lung cancer, stomach cancer, intestinal cancer, esophageal cancer, pancreatic cancer, breast cancer, ovarian cancer, cervical cancer, malignant lymphoma, etc. This rule is more obvious. is more obvious. Therefore, this age is considered by both Chinese and Western medicine as the point when the body function starts to decline, especially the disorder and decline of various immune functions, resulting in the body not being able to effectively monitor the mutated cells and harmful factors in the body for timely removal, which finally leads to the occurrence of malignant tumors over time. At the same time, this age is often the peak period of career development in life, shouldering various burdens of social development, personal career and family happiness, if they cannot reasonably adjust their functions, it is more likely to lead to the occurrence of malignant tumors. Therefore, the author strongly recommends that a yearly physical examination should be conducted systematically from the age of 40, and even timely consultation should be made when feeling unwell, so that malignant tumors can be ruled out in time by systematic examination. The methods of physical examination include routine physical examination, biochemical examination, various imaging examinations such as ultrasound, CT, MRI, PET and genetic testing. However, the author does not recommend PET as a routine examination, but to use it for differential diagnosis according to the situation. After the above screening, most of the malignant tumors can often be detected. 2.Definition of population with high risk of malignant tumor Long-term clinical research has found that malignant tumor has its own high-risk population. They mainly include elderly people over 60 years old, family history of malignant tumor, long-term exposure to carcinogenic factors such as coal miners, long-term smokers, long-term alcoholics, drug addicts, etc. Patients with long-term chronic diseases, which are often complicated by immune function decline or various chronic inflammatory diseases, proliferative diseases, wasting diseases, metabolic diseases, have higher risk of malignant tumor than other people and are more likely to develop malignant tumor. The risk of malignant tumor is higher than other people, so they need to have a strong awareness of malignant tumor prevention. Do not wait until you are 40 years old to start systematic physical examination, you can have timely physical examination under the guidance of oncologist. The treatment effect of malignant tumor is closely related to the clinical stage at the time of clinical detection. In principle, the earlier the treatment, the better the treatment effect and the chance of cure is significantly higher. Take lung cancer, which has the highest incidence and mortality rate, as an example, the chance of cure for early stage lung cancer patients with lesions confined to localized areas is more than 80%, while the 5-year survival rate for advanced stage patients with metastases is only about 5%, which is a world of difference. In addition, the cost of early treatment is far lower than that of advanced patients, and there are fewer treatment-related complications, and patients have higher quality of survival. 4. Accumulate positive energy and actively prevent malignant tumors The author wrote an article last year, emphasizing the key role of maintaining one’s own health in tumor prevention and treatment, and not relying too much on drugs and health care products. A good and healthy lifestyle, an optimistic and open-minded attitude towards life, and a positive and good attitude are the necessary conditions for maintaining one’s own health, which can later improve one’s own immune function and thus timely remove the undesirable factors that have mutated in the body from the body. When let, if check out certain physical abnormalities and need drug intervention, also under the guidance of experts in a timely and scientific application of some Chinese and Western drugs or health products, but must prevent excessive intervention. Overall, the author believes that maintaining health by oneself has a vital role in tumor prevention. After all, the external social and natural environment is not something that individuals can change at any time. But the adjustment of one’s own lifestyle and attitude is the most effective and feasible way. Finally, I wish all readers can live a healthy life and stay away from malignant tumors.
