Tumors can indeed occur at any age, but the peak of tumor onset is after 50 years old, and the risk of tumor onset increases with age. A 65-year-old person is more than 50 times more likely to have a tumor than a 25-year-old person. Among the elderly over 50 years old, 1/5 to110 diseases are all tumors.
Therefore, the elderly over 50 years old and "quasi-elderly" should be regarded as cancer risk groups. Regular physical examination can find tumors early.
2. People exposed to carcinogens
That is, occupational tumors, such as radiation workers, asbestos workers, uranium miners and reactor workers. If people who work in a carcinogen environment smoke and drink, it will inevitably aggravate the stimulation of carcinogens.
These people must have regular inspections, strengthen labor protection, and change jobs when necessary.
3. High-risk groups caused by genetic factors
Tumors are the result of the interaction between individual genetic disorders and carcinogens in the environment. Some tumors have family aggregation and genetic susceptibility, which means that people with family history of tumors have a higher probability of developing tumors than the general population. For people with genetic genes and family history of cancer, we should actively carry out anti-cancer propaganda, implement preventive measures, check regularly and deal with cancer-related diseases as soon as possible.
4. Patients with precancerous lesions
Before the onset of tumor, benign diseases may occur, and eventually they will evolve into tumors under the action of carcinogenic factors. We should understand and prevent these precancerous lesions and stop the interpretation of precancerous lesions. Attention should be paid to this group of people in clinical cancer prevention, because some of them may become cancer patients.
5. Tumor patients after treatment
If it is not cured, the tumor will recur or metastasize, and a considerable number of tumor patients will suffer from cancer repeatedly. Tumor patients may have many precancerous lesions, which will continue to become malignant and appear new lesions. Therefore, it is necessary to radically cure tumor patients, carry out comprehensive treatment, eliminate subclinical lesions and prevent recurrence and metastasis.
