Radiation therapy is often used along with other lung cancer treatments to target specific areas of cancer. The most common type of radiation therapy is external-beam radiation, which uses high-energy X-rays on the outside of the body. However, you may have access to other types of radiation therapy treatment options, including when radioactive material is placed inside the body to destroy cancer cells.
Your care team will guide you through what to expect with your specific type of radiation therapy and treatment goals. Sometimes, radiation therapy helps make a lung tumor smaller before surgery. Other times, radiation therapy is used to slow the cancer growth and reduce symptoms when surgery isn’t an option.
In small cell lung cancer, it’s common for cancer cells to spread to the brain. To help reduce this risk, you may also have radiation therapy in the brain as a preventive step.
