Radiotherapy| treats cancer by using high-energy rays which destroy the cancer cells, while doing as little harm as possible to normal cells.
Radiotherapy treats cancer by using high-energy rays that destroy the cancer cells, while doing as little harm as possible to normal cells. Radiotherapy is occasionally given to the head as part of CNS-directed therapy|. The course of treatment is given in the hospital radiotherapy department, usually in 8-10 sessions (fractions) over two weeks. The treatment is given on weekdays with a rest at the weekend. Your doctor will discuss your treatment with you in detail beforehand.
If you need to have high-dose treatment| with stem cell support you may have a special form of radiotherapy called total body irradiation (TBI). This is where radiotherapy is given to the whole body to destroy the leukaemic bone marrow cells.
