Radiation Therapy for Non-Melanoma Skin Cancer
A machine is used to target high-energy rays specifically at the cancerous area. Radiation therapy (also called radiotherapy) is not a common treatment for skin cancer, but may be used in certain instances, such as when the cancer is in an area that makes surgery difficult or when the patient is not a good candidate for surgery because of age or health reasons. This treatment may also be used in very advanced cases or when skin cancer recurs after initial surgical treatment.
The way in which radiation therapy is delivered depends on the extent and type of non-melanoma skin cancer that is being treated:
- External radiation therapy is delivered by a machine that aims radiation beams directly to the cancer site.
- Internal radiation therapy is given by sealing radioactive medicine in a small device, such as a needle, “seed,” wire, or catheter (thin, hollow, flexible tubing), that is placed directly into or close to the site of the cancer.
Side effects from radiation therapy are common but usually temporary. They may include soreness, redness, or blistering at the radiation site, or hair thinning or loss.
