For certain types of cancer, a combination of radiation therapy, surgery and/or chemotherapy is more effective than having just one type of treatment.
Chemotherapy is a drug treatment which circulates around the whole body through the bloodstream to destroy cancer cells. Chemotherapy is often used when cancer may have spread to another location in the body. When given at the same time as radiation therapy, chemotherapy can also increase the effectiveness of radiation on cancer cells.
Surgery can be very effective to remove tumours from the body. Sometimes radiation therapy is used to make a tumour smaller before surgery or as an extra precaution in case any cancer cells were left behind after surgery.
