Radiation therapy aims to kill cells by treating specific areas of the body. Like chemotherapy, radiation kills both cancer cells and healthy cells.

If you’re going through radiation therapy that targets any part of your head or neck, or your digestive system, you may experience side effects that make it harder to take in the nutrition you need to keep your strength up during treatment.

It’s the dosage of radiation therapy that often determines how severe these side effects are for you. You may begin to see them two to three weeks after you begin radiation and taper off a few weeks after your treatment ends, although some may continue longer.
