Under what circumstances do you need chemotherapy?

Chemotherapy is a commonly used treatment for malignant tumors. Chemotherapy is used to eliminate cancer cells to cure the disease, control the progression of the disease and reduce the chance of recurrence. If it is an early stage malignant tumor, there is no metastasis of surrounding tissues within the first stage. After radical surgery, it can basically achieve clinical cure without chemotherapy.

When malignant tumors enter the second stage, different degrees of metastasis and diffusion can occur. Simple surgery cannot completely eliminate cancer cells, so chemotherapy is needed to consolidate the treatment effect. However, some malignant tumors are not sensitive to chemotherapy and may need radiotherapy.
