other three are surgery, chemotherapy, and biological therapy. Since each type of
cancer is unique, research has helped physicians determine which treatment or
combination of treatments is appropriate for each type of cancer. Radiation therapy may
be used alone or in combination with surgery, chemotherapy, and/or biological therapy.

Cure - Answer-Radiotherapy given with the aim of curing the cancer on its own or
combined with other treatments. Such as surgery or chemotherapy. This may be called

Internal Radiotherapy - Answer-A radiation source is placed inside the body on or near
the cancer.
This includes Brachytherapy, where a temporary or permanent radiation source is put
