Chemotherapy is one of the most effective treatment methods to save cancer patients' lives and is the only systemic treatment method.
can kill the damaged cancer cells in the body through chemotherapy and reduce the probability of cancer recurrence and metastasis in the human body. is limited after all, and it cannot guarantee that the tumor will be completely removed.
Although there are new methods for treating cancer every year now, there is still no good method to replace chemotherapy. At present, , chemotherapy is still the most commonly used treatment method for cancer patients.

The role of chemotherapy
Chemotherapy is actually a double-edged sword. It also kills cancer cells while also destroys healthy cells in the body.
Many people will have some side effects during chemotherapy, such as , such as leukocyte decline, diarrhea, anemia, , vomiting, hair loss, , these side effects usually gradually recover after chemotherapy is stopped.
And the side effects of chemotherapy vary from person to person, and each person has different physical constitutions, so the symptoms after chemotherapy are also different. Before giving chemotherapy to the patient, the doctor will first determine whether the patient can withstand chemotherapy.
Although chemotherapy will bring side effects to the body, if cancer patients actively cooperate with the doctor's treatment plan and choose the corresponding chemotherapy method according to the specific situation of the tumor, many malignant tumors can also be cured.

Not all cancer patients can undergo chemotherapy
1. The patient's physical condition is too poor, and he is too old
There are some cancer patients, because they are tortured and consumed by diseases for a long time, resulting in a very poor nutritional status in the body. looks thin and thin. In addition, the body may find it difficult to withstand the side effects of chemotherapy. In this case, chemotherapy is not recommended.
2, 1, 1, chemotherapy has serious side effects. If chemotherapy is forcibly performed, some patients with are intolerant to chemotherapy, which may not achieve the ideal effect, which will increase the development of the disease.
3 and Patients who have no effect on multiple chemotherapy
Each chemotherapy session requires checking whether the patient's lesions appear. If the condition of does not improve after multiple chemotherapy, the cancer cells in the body have become resistant to chemotherapy drugs. In this case, chemotherapy cannot be controlled, so continuing chemotherapy is not of great significance. It is not recommended to undergo chemotherapy again for this type of patients.
4, Patients with abnormal organ function
Some patients have special physical conditions, such as , for example, people with poor cardiopulmonary function or severe respiratory dysfunction, will experience different degrees of infection after chemotherapy, and patients like are not suitable for chemotherapy.

Doctor advises: Two types of cancer do not require chemotherapy, which may have a counter-effect. Don’t blindly treat
1. Cancer with earlier stages
In terms of medical clinical practice, cancer is divided into stage I/II/III/IV, a total of 4 stages, among which stage I can be subdivided into Ia and Ib. Ia stage does not need to be treated with chemotherapy after surgery.
In other words, the earlier the cancer is found, there is no sign of metastasis, and chemotherapy is basically not required after surgery.
2. Cancers that are insensitive to chemotherapy
Cancer is different in different personal constitutions, and also has different sensitivity to chemotherapy drugs . Some cancers are not very sensitive to chemotherapy. Even if chemotherapy is used, it is difficult to have obvious effects. For example, liver cancer , pancreatic cancer , etc. Chemotherapy drugs will not have sensitive effects, and chemotherapy is usually not recommended.

What harm will excessive chemotherapy cause to the body?
Excessive chemotherapy or improper use will not only not be effective in treating cancer, but will also reduce the quality of life of patients and even lead to life threatening.
has undergone metastasis or relapse after surgery, the efficiency of chemotherapy is only 25% to 35%, and the efficiency of advanced cancer patients who are ineffective against chemotherapy is about 70% , especially for melanoma, liver cancer, renal cancer , colon cancer , etc., which is even less efficient.
So before patients receive chemotherapy, must first analyze whether it is worth 30% short-term efficacy and endure 100% side effects of chemotherapy.
Many people may not understand what the efficacy of 30% means. In fact, simply put, 7 out of 10 people cannot control the tumor through chemotherapy. The remaining three people may be able to control the tumor to a certain extent with the help of chemotherapy.
Of course, this process is not controlled indefinitely. can last for only a short period of time usually 2 to 6 months.
And after the tumor recurs, it will also develop drug resistance, resulting in faster growth rate, so the efficiency of chemotherapy is less than 10%, and the toxicity of chemotherapy will be greater.
