A: I am a normal cell in the human body, the most basic unit that constitutes the human body. By exercising normal functions, I ensure the normal work of organs and maintain the health of the human body, and thus am loved by people. B: I am a cancer cell evolved from a normal cell, which is the culprit of cancer and thus hated by people. In fact, A and B used to be very good friends, working on different organs of the human body, and the two work in coordination to ensure the normal metabolism of the human body. A and B had not met for more than ten years, and once they met by chance, A could hardly recognize B, because B had become a misguided, faceless, malignant cancer cell. A: Are you B? What has happened over the years? How did you become a cancer cell that everyone hates? Do you know how harmful the cancer you caused is to human health? B: I am your former good friend B. Is cancer really scary? A: Let me tell you, now cancer has become the number one killer that endangers the lives and health of the general public. The ratio of malignant tumor deaths in the total number of deaths is significantly higher, reaching about 20%, which means that one out of every 5-6 people alive now will die of malignant tumor sooner or later. At present, the treatment of malignant tumor still lacks certain effective means, and cancer patients often suffer more pain and bring great spiritual and material losses to their families. B: I never thought I caused such a great harm, no wonder I became the object of people’s crusade and execution after I turned into a cancer cell. A: What do you think is different between yourself and before after turning into a cancer cell? B: I feel that my growth rate is developing rapidly, and I am a wild horse that is out of control, not under the control of my body. A: Yes, this is the growth characteristic of cancer cells. Due to the mutation or deletion of genes in cancer cells, the activity of genes that promote cell growth increases, while the activity of genes that inhibit cell growth decreases, thus causing the loss of cell stability, growth loss of control and abnormal proliferation to form tumors. In addition, malignant tumor has another fatal characteristic of invasiveness and metastasis. Cancer cells are not only confined to one organ, but also can wander to other suitable growth sites and continue to proliferate without restriction, resulting in the destruction of multiple organs in human body and thus threatening life. B: We live together in the same environment, how come you can stay healthy while I become cancerous? A: The occurrence and development of cancer are influenced by genetic and acquired factors, which first of all requires our own awareness, because exposure to carcinogens is the main cause of cancer, some research surfaces that 1/3 of malignant tumors are related to smoking, 1/3 are related to unreasonable diet, the rest 1/3 are related to infection, occupational exposure and environmental pollution, and only 1/-3% are caused by genetic factors, I think you must be exposed to more carcinogens in your daily life. I think you must be exposed to more cancer-causing factors in your daily life. B: You are right, I usually don’t pay attention to the details of life, I am addicted to smoking and alcohol, I have an irregular life, I love to eat some barbecue and pickled food, and I don’t pay attention to exercise, I think this is the main reason why I turn from normal cells to cancer cells. A: That’s right. In fact, the process of cancer transformation is a long period of time. In the current reality that the cause of cancer is unknown and the treatment effect is unsatisfactory, it is most important to do a good job of prevention, and to strongly advocate the establishment of healthy and scientific eating habits and lifestyle, it is entirely possible to ensure that the cells do not become cancerous. B: I have some friends who have many vices like me, and I guess they are now hovering in the ranks of imminent cancer, how to save these cells. A: These cells should belong to the high-risk group of cancer. We advocate “three early stages” for these cells, i.e. early detection, early diagnosis and early treatment, and actively participate in screening and physical examination regularly to kill the cancerous cells in the cradle. Nowadays, many cancers have good screening methods, such as high-risk HPV test for cervical cancer, self-examination and radiography for breast cancer, fecal occult blood test and colonoscopy for colorectal cancer, and gastroscopy for esophageal cancer and gastric cancer, which can detect precancerous lesions and early cancerous events in a timely manner, and minimally invasive treatment can be carried out to achieve very good clinical results. B: I then neglected regular medical checkups. I sometimes found some abnormal changes in myself, but did not pay enough attention to them, which resulted in today’s consequences. Therefore, I advise my brothers and sisters in the body to be less exposed to carcinogenic substances and regular medical checkups are crucial to prevent and treat cancer, so that they will not be like me and have no way to go back, only to be hated by others and bring pain and harm to their bodies.
