Radiation Therapy for Prostate Cancer
Radiation therapy, also called x-ray therapy, uses high-leveled radiation to kill prostate cancer cells or keep them from growing and dividing, while minimizing damage to healthy cells.
External radiation (outside of the body) can be produced from a machine and directed right at the prostate into the cancer-infected area.
Internal radiation therapy places radiation implants directly into the tumor. These radioactive sources can be temporary (removed after proper dose delivery) or permanent.
If you have questions or need additional information about radioactive treatment for your prostate cancer, ask your doctor.
