Radiation

Radiation therapy is used to treat cancer by exposing the cancer cells to radiation and damaging their DNA. Radiation may be used alone or with other treatment options. Tissue cells respond differently to radiation and some organs are more susceptible to damage caused by the radiation than others. A radiation oncologist will schedule image scans to determine the location and size of the suspected tumor and then discuss your treatment plan. If you have previously received radiation therapy, then your physician will decide if that area can be treated a second time. This will depend on the amount of radiation you received and the location of the previous treatment.

There are several different types of radiation therapy a radiation oncologist may prescribe depending on the type and size of the cancer, its location in the body, and the overall health of the patient. The types of radiation therapy include:
