Abstract People of any age can get cancer, but they are more likely to get cancer as people grow older. Generally, people over the age of 40 are most susceptible to cancer. Experts pointed out that this may be related to the following factors.
People of any age can get cancer, but they are more likely to get cancer as people get older. Generally, people over the age of 40 are most susceptible to cancer. Experts pointed out that this may be related to the following factors.
First, there is a long incubation period before cancer occurs. After the carcinogenic factors act on the human body, the disease will not occur immediately, and it often takes 15-30 years of carcinogenic incubation period. Generally 20 years. Therefore, if you are often exposed to carcinogens at the age of 20-30, you will not develop the disease until you are 40-50 years old, so the age of cancer will appear to be older.
Second, with old age, the body's immune function weakens, so the role of immune surveillance for lesions gradually decreases from the age of 40. The weakening of immune function is conducive to the occurrence and development of tumors.
Third, the older you are, the more opportunities you have to be exposed to carcinogenic factors, and the impact of carcinogenic factors on the body will become greater and greater. For example, for smokers, the longer the number of years of smoking, the more likely they are to develop cancer. It also increases.
Fourth, lung cancer, gastric cancer, prostate cancer, colorectal cancer, and cervical cancer in the elderly may cause various chronic inflammations, chronic bronchitis, gastritis, ulcer disease, prostatitis, enteritis, Inflammation of the cervix, etc.
While tissue decline in the elderly is unstoppable, cancer can be avoided. Such as active physical exercise, improve physical fitness and health level, develop good hygiene habits, pay attention to diet and nutritional balance, actively prevent and treat various chronic diseases to prevent cancer, do a good job in health care, regular physical examinations, and strive for early detection and early treatment of cancer.
