Radiation therapy is used to target and kill cancerous cells using X-ray beams. Usually, the X-rays are directed externally but small radioactive rods can be inserted internally close to the tumor called brachytherapy.
Radiation therapy is one of the most common treatments for mesothelioma patients, particularly if surgery is not possible. It’s often used in addition to surgery to target small cancer cells that surgery may miss.
Side effects of radiation include skin rashes, a sunburn effect at the entry site, and fatigue.
