How is radiation therapy used to treat skin cancer?

Radiation therapy shrinks tumors with x-rays aimed at the affected area of skin from outside the body.

Doctors may choose to treat some types of skin cancer with radiation therapy. In this procedure, doses of high-energy radiation (like x-rays) are aimed at the tumor to destroy cancerous cells. Usually, this type of treatment is used for tumors in areas where surgery would be difficult, such as the ears and eyelids. Radiation may also be used after surgery to kill any remaining cancer cells, or for cases in which cancer has spread to the lymph nodes or other areas. Talk to your doctor to determine whether radiation therapy may be a good treatment option for you.
