Malignant tumor, also known as cancer, is a knife hanging on people’s heads, threatening people’s lives at any time. Although medical technology has been developed, cancer can still lead to death. The effect of early cancer treatment is very good, but the cure rate of late cancer is not high. < / P > < p > nowadays, the treatment of malignant tumor is usually through surgery, and the tumor is removed, but is it over after removal? Of course not. If cancer is so easily cured, it’s not called cancer. After the operation, chemotherapy is usually needed. < / P > < p > as an adjuvant treatment for cancer, chemotherapy plays a very important role in the treatment of cancer. Through the naked eye, doctors can only see the malignant tumor that has been formed, and remove it by surgery. However, there are many invisible cancer cells that cannot be removed by surgery, and they are still active in the human body. Of course, limited to the difference of medical devices or the level of doctors, the tumor may not be completely removed. < / P > < p > at this time, through chemotherapy, these residual cancer cells can be removed, although not completely removed, but most of the cancer cells can be removed, which has made a great contribution to prevent the recurrence of cancer again. But the side effect of chemotherapy is also very big, it can not only kill cancer cells, but also normal cells, so it will lead to some adverse reactions after chemotherapy, reduce people’s resistance, easy to cause various diseases. Although the side effects of chemotherapy are great, compared with cancer recurrence, the advantages outweigh the disadvantages. < / P > < p > although chemotherapy has a good effect on the treatment of cancer, chemotherapy is also divided into people, not everyone is suitable for chemotherapy, some people do chemotherapy will have serious consequences, who is it? Let’s have a look. < / P > < p > in the first category, people whose cancer has spread and metastasized are very thin and in poor condition. This kind of people, first of all, the effect of chemotherapy has been very small, there is no significance, in addition, the body is very thin, immunity is very low, can not withstand the damage of chemotherapy, the process of chemotherapy will only aggravate the degree of illness. At this time, it should be advanced cancer, the important thing is not treatment, but to reduce the suffering of patients and improve the final quality of life of patients. < / P > < p > in the second category, renal function has been overdrawn, and severe renal insufficiency. Chemotherapy drugs themselves have side effects. Liver and kidney are detoxification and detoxification organs of human body. If the kidney function is not complete, then the toxin of chemotherapy drugs can not be discharged from the body, so the harm to human body is huge. Therefore, such patients forced to chemotherapy, will only make the body worse and worse. < / P > < p > the third group is people with bone marrow suppression. This kind of people can accept chemotherapy at the beginning of a week, but after chemotherapy, the bone marrow is suppressed, the white blood cells and platelets in the body are greatly reduced, and the side effect of chemotherapy itself is to damage normal cells, white blood cells and platelets are also one of them, if they have not recovered, then the consequences are very serious. < / P > < p > in general, chemotherapy is not omnipotent, some people have bad life, suffer from cancer, after surgery can not chemotherapy.
