Chemotherapy is a very common anti-tumor treatment. Chemotherapy has no radiation unlike other radiotherapy or radioactive tests. Chemotherapy is a chemical treatment, mainly through intravenous chemotherapy, but also some oral chemotherapy drugs, such as Tegretol and Capecitabine, which are two commonly used oral chemotherapy drugs. Commonly used chemotherapy regimens include intravenous chemotherapy combined with oral chemotherapy or alone, depending on the patient’s pathology and physical condition. Although chemotherapy has no radiation, there are some other side effects, such as may cause myelosuppression, white blood cell drop, anemia, platelet drop, and so on. The most common ones are allergic reactions and gastrointestinal reactions, such as nausea and vomiting. So you need to use the drug in advance to prevent side effects.
