The surgical procedure chosen depends upon the size and location of the tumor. Radiation therapy may be employed Radiation therapy uses high-energy X-rays or other types of radiation to kill dividing cancer cells. Chemotherapy refers to the administration of drugs that stop the growth of cancer cells by killing them or preventing them from dividing. Chemotherapy may be given alone, as an adjuvant to surgical therapy, or in combination with radiotherapy.
