Radiation therapy has some side effects

Normal cells can be affected by radiation therapy used to destroy cancer cells in the body. These side-effects are usually localized close to the cancer. Although many of the side-effects are expected, their specific nature will vary in each patient depending on the type of cancer, the strength of the radiation and especially the area of the body where the treatment is administered.
Each patient will experience radiation therapy differently, however side-effects usually appear a few weeks after treatment. Rarely does a patient experience every side-effect. Fatigue, nausea and skin irritation are the most common side-effects reported by cancer patients who have received radiation therapy.
Talking to your Radiation Oncologist and nurse about any side-effects that occur, no matter how temporary, is important. They will have medication that can be prescribed to reduce side-effects. Do not use any home remedies, creams, or medicines without first consulting with your radiation oncologist or nurse and receiving their permission.
Side-effects can begin within two to three weeks after beginning treatment and can continue for up to four weeks after ending treatment. As the damaged cells return to normal, the side-effects will gradually decrease.
Discuss with your Radiation Oncologist or nurse what your follow up arrangements will be once the treatment is completed. Working together with your team will help you control the side effects that you experience as you go through radiation therapy. The advice most often given will be to contact your local doctor if problems persist after treatment is completed.
