Radiation therapy for basal and squamous cell skin cancers
Radiation therapy is treatment with high-energy rays (such as x-rays) to kill cancer cells. The radiation is focused from outside the body onto the skin tumor.
When radiation is used to treat skin cancers, it is often done with electron beam radiation. This type of treatment uses electrons, which do not go deeper than the skin. This helps limit the side effects in other parts of the body.
Radiation may be used as the main treatment instead of surgery if the tumor is very large, or if it is in an area that makes surgery hard to do. It might also be used for people in poor health who can’t have surgery.
In some cases, radiation can be used after surgery to lower the risk of cancer coming back. Radiation may also be used to treat skin cancer that has spread to lymph nodes or other organs.
The process is much like getting an x-ray but the radiation used is stronger. Each treatment is painless and lasts only a few minutes, although the setup time – getting you into place for treatment – takes longer.
Possible side effects of radiation treatment
Side effects of radiation can include skin irritation, redness, dryness, and hair loss in the area being treated. With longer treatment, these side effects may get worse. After many years, new skin cancers may start in areas that had been treated with radiation. Because of this, radiation is not usually done to treat skin cancer in young people or in others who are at higher risk for new skin cancers.
