What is the significance of chemotherapy for tumors

Patient's question:

Doctor, let me think and consult you a question. My friend has a benign tumor, it seems to be in the lungs. Recently, they underwent chemotherapy for small cell lung cancer and are feeling good. The tumor has disappeared after radiotherapy and chemotherapy. What is the significance of chemotherapy for the tumor?

Doctor's answer:

Of course, your trust is natural. Internal medicine treatment does not necessarily imply that it is solely chemotherapy, but chemotherapy is only a small part of it and is highly expected. Clinical medicine clearly states: For stage III non-small cell lung cancer patients undergoing radiotherapy and chemotherapy, the number of chemotherapy cycles is between 2 and 4, because tumors naturally grow in the human body, especially after the age of 60, some tumors can gradually disappear. For severely ill lung cancer patients, it is recommended to seek medical attention immediately and follow the doctor's advice for prompt treatment. Do not switch to new medications at will, otherwise the efficacy may be counterproductive.
