The incidence of most tumors increases with age, and the elderly are the most prevalent group of tumors. 2013 saw the first publication of China’s Annual Tumor Report, from which two things are clear: first, the incidence of cancer increases exponentially from the age of 40 onward, regardless of gender; second, older men are more likely to develop cancer than women, mainly because a large number of men develop prostate cancer. Japan also reported that cerebrovascular accidents, which originally accounted for the first death, have given way to malignant tumors. All these show that malignant tumors are a serious threat to the life and health of middle-aged and elderly people. Today, we provide a suggestion of cancer prevention checkup for middle-aged and elderly people who are children. As the saying goes, a gift is a gift! So, what makes middle-aged and elderly people vulnerable to the threat of tumors? First of all, the formation of tumor is often the result of years of chronic stimulation and long-term exposure to carcinogenic substances, which is a longer-term process, and generally the latent period of tumor is 10-30 years. Therefore, when young, the cells undergo abnormal changes due to certain cancer-causing factors, and only at the age of 40-50 do they start to develop, forming the peak of tumor development in middle and old age. Secondly, after entering middle age, with the decline of whole body functions and lower immunity, the immune surveillance and removal of tumor cells are reduced, and the body is easily affected by various external cancer-causing factors. Prevention is the key to keep away from tumor! In addition to regular medical checkups, healthy living habits can also save middle-aged and elderly people from the torment of diseases and help them to enjoy a healthy life. In the Yellow Emperor’s Classic of Internal Medicine, it is written that “the ancient people, who knew the law of yin and yang and the arts and figures, ate and drank in moderation and lived in harmony. They ate and drank in a disciplined manner, lived in a regular manner, and did not make delusions of labor, so that they could be in form and in spirit, and end their natural life, and go away after a long time.” As children concerned about their parents’ health, we should remind them to do the following: “The tree wants to be quiet, but the wind does not stop; the son wants to raise, but the parents do not wait”. Caring for your parents’ health starts now.
