Under what circumstances should chemotherapy be used?

Chemotherapy is mainly used to treat malignant tumors, especially in patients with advanced malignant tumors or metastases, adjuvant therapy before surgery, adjuvant therapy after surgery, tumors sensitive to chemotherapy, and patients who cannot tolerate surgery or radiotherapy.

1. Advanced or metastatic cancer

When cancer has spread to other parts of the body and surgery is difficult to completely remove, chemotherapy can help control the disease and prolong the survival

of the patient.2. Adjuvant treatment before surgery

For some large or locally advanced tumors, chemotherapy before surgery can shrink the tumor and improve the success rate of surgical resection.

3. Adjuvant treatment after surgery Chemotherapy after surgery

can kill residual cancer cells and reduce the risk of recurrence and

metastasis.4. Chemotherapy-sensitive tumors

Some types of tumors are very sensitive to chemotherapy drugs, such as lymphoma, leukemia, etc. Chemotherapy can be used as the main treatment.

5. Patients who cannot tolerate surgery or radiotherapy Chemotherapy

can be used as a relatively mild treatment option for patients who are older, in poor physical condition, or who cannot tolerate surgery or radiotherapy.
