Chemotherapy, as one of the important means of clinical comprehensive treatment of malignant tumor, can kill the residual tumor cells in patients, improve the curative effect and prognosis, but because of the toxic side effects of long-term and repeated chemotherapy, such as digestive tract reaction, bone marrow suppression, neurotoxicity, liver and kidney function damage, cardiotoxicity, alopecia and so on, chemotherapy is often forced to terminate, and even the mortality rate is increased due to serious complications of chemotherapy. In fact, people who have experienced chemotherapy know about the side effects of chemotherapy, but they still don't believe it. Chemotherapy is not a cure, why can it kill people instead? This is a "double-edged sword" effect, and chemotherapy is a double-edged sword. This is the root cause of why chemotherapy dies quickly.

No matter how many times chemotherapy brings the side effects to the body, the digestive tract reaction, hemogram reaction and so on will become more and more intense with the increase of chemotherapy times. With the increase of the number of chemotherapy, one can't stand it, and the other is the decrease of chemotherapy, which means drug resistance. Drug resistance is the biggest obstacle to the treatment of tumors, and it is also the main factor of clinical common chemotherapy failure. Therefore, chemotherapy combined therapy is often seen in clinic. For example, Shenbaiyi, a traditional Chinese medicine, is used to help alleviate the pain of chemotherapy. The purpose is to prevent cancer cells from growing and metastasizing after chemotherapy fails.
