Do I need chemotherapy after cancer surgery?

Chemotherapy is not always needed after cancer surgery. Whether chemotherapy is needed depends on the type of cancer, stage, whether the surgical resection is complete, whether there is a risk of metastasis, and the patient's overall health.

For early-stage, low-risk cancers, such as some early-detected thyroid cancers and basal cell carcinomas of the skin, chemotherapy may not be necessary after surgical resection, and regular follow-up is sufficient. For mid- to late-stage cancers or those with a higher risk of recurrence or metastasis, such as colon cancer, breast cancer, or lung cancer, even if the surgery is successful, chemotherapy may be needed to kill residual cancer cells and reduce the chance of recurrence. Chemotherapy usually includes intravenous infusion of drugs, oral medications, local injections, etc. The specific plan needs to be formulated by the doctor according to the condition of the disease. Commonly used chemotherapy drugs include paclitaxel (for breast cancer, etc.), cisplatin (for a variety of cancers), and gemcitabine (for the treatment of lung cancer, etc.).

Regular follow-up during the postoperative recovery period is essential. Following the doctor's instructions for chemotherapy, adjusting diet, and maintaining moderate exercise can help the body recover faster and avoid the risk of recurrence. If the patient has doubts about whether chemotherapy is needed, they can choose to consult a second medical opinion to ensure scientific treatment and a clear plan.
