Chemotherapy is the chemical treatment with drugs and hormones that are in the body’s system. Many normal cells are also damaged in this process, and it can cause the patient to feel quite ill for a while, but can, and often does, lead to remission of the cancer.
Radiation therapy. External x-rays at high levels are directed towards the tumour with a view to damaging or destroying the cancer cells.
Surgery. This is still the most obvious response, if the tumour is small and limited to a single area of the body.
