What is a Radiotherapist?

Radiotherapy, or radiation therapy, is therapy using ionizing radiation, usually X-rays, to damage the DNA of cancer cells. It is usually part of treatment plan for cancer, either benign or malignant tumours.

Radiotherapy can be used to cure cancers (curative), control symptoms (palliative), shrink a tumour before surgery to reduce risk (neoadjuvant), kill remaining cancer cells after surgery to prevent cancer from coming back (adjuvanant) and kill old bone marrow cells to prepare for bone marrow transplant (total body irradiation). It can also be coupled with chemotherapy – usage of chemical substances, synergistically.
