Radiation Therapy

Radiation therapy is a non-invasive procedure that uses low doses of radiation to kill cancer cells. Radiation therapy typically requires 20 to 40 sessions over four to six weeks and is used to treat both the tumor and some surrounding normal tissue. The normal tissue is typically not as susceptible to small doses of radiation as the tumor cells, so the extended courses of radiation therapy result in minimal destruction of normal cells for the patient.

Radiation therapy is typically used on large tumors, tumors that aren’t well defined and have possibly spread into some of the surrounding tissue, and tumors that do not require intrafraction motion tracking.
