1.Why are more and more people getting cancer when life is getting better? This statement is not accurate. There are many reasons for this impression. One is because with the development of medical science and the improvement of diagnosis and treatment technology, cancer is diagnosed more and more often. Secondly, because the average life expectancy of people has increased and tumors are more common in the elderly, the number of cancer patients has increased. Of course, it is undeniable that with the increase of environmental pollution and competitive pressure, some diseases may increase, but it is not “more and more” as we feel. Globally, the incidence of some cancers is still decreasing, such as cervical cancer. 2.Why do we get cancer? The cause of tumors is complex, but now it is proven to be a genetic lesion. People are made up of genetic code, and genes determine the occurrence and development of lesions. Of course, factors such as living environment, diet, social pressure and emotional changes can have influence on any disease including tumor. For example, consuming moldy food, pickled food (bacon, pickled vegetables), food that is too hot, or having the habit of betel nut chewing increases the possibility of developing tumors in different organs or tissues. Another cause of tumor generation is the infection of virus, for example, hepatitis B virus infection is an important cause of liver cancer in our country. In most cases, there is no single cause for tumor occurrence. 3.Can cancer be cured? Cancer is a preventable and treatable common disease, it is indeed not curable, especially in the middle and late stages, but if detected early and treated early, most tumors can be cured. 4.How can we do early detection and curb cancer in its early stage? The most important thing is to raise self-care awareness. For example, self-examination of breast is an effective way to detect breast cancer early, and being alert to unexplained wasting, blood in stool, cough and other symptoms that may not be obvious in the early stage of cancer, as well as regular medical checkups, can help in early diagnosis of cancer. 5. Is cancer hereditary? Individual tumors have genetic tendency and there are genetic factors in their development, but tumor disease is not equal to genetic disease. 6.Is cancer contagious? In principle, it is not contagious, but it may be related to infectious diseases in the process of development. For example, hepatitis B itself is contagious, and in China, it is an important cause of liver cancer, and many liver cancer patients have hepatitis B in the early stage. We can say that some tumors are caused by infectious diseases, but the case of direct transmission of tumors does not exist in general. 7.Should I recuperate or exercise more when I have cancer? If you have the disease, you should first go to the hospital for treatment. During the recovery period, you should listen to the doctor’s advice whether to rest or to exercise more, and these two aspects are not distinctly separated. Doctors do not advocate that patients should be disconnected from society and lie at home to recuperate, but proper participation in exercise and socialization is beneficial to recovery. 8.Do I have to suffer from deadly pain if I have cancer? No. Patients with mid- to late-stage cancer will have painful symptoms, but not necessarily everyone is in pain, and the pain problem of cancer patients has been given considerable attention. 9. Is chemotherapy very painful? Chemotherapy is one of them, but it varies from person to person, from drug to drug, and from disease to disease, some chemotherapy is not very painful, and now there are corresponding methods to reduce the side effects of chemotherapy. 10.How can cancer patients get through the psychological difficulties? While treating the physical pain of patients, oncologists have the obligation to help patients to make good psychological recovery and build up their confidence to overcome the disease. People have various attitudes and psychological activities during illness, some are open and optimistic, while many others are fragile and desperate. The same disease, the same period of illness, the former has a better prognosis than the latter, because their immune status is different. Even if the drug enters the body, it depends on the patient’s active mobilization for it to work, so it is clear that the patient’s mental state plays a very important role.
