Radiation cancer treatment is a local therapy, meaning that its side effects are dependent on the location of the cancer, your general health and other treatments you are receiving. Short-term side effects of treatment can appear within weeks, while long-term effects may not appear for months or even years afterward.
Fatigue
Fatigue is a common side effect that can fluctuate from mild to severe when undergoing radiation treatment. Finding ways to meditate, relax and balance a more moderate schedule are keys to reducing the stress fatigue can cause.
Hair Loss
Hair loss is one of the most recognized side effects of radiation treatment; however, this occurs only at the area being treated. Only individuals receiving radiation treatments to their head should lose hair in that area; hair growth resumes after you complete the treatments.
Skin Irritation
Skin located over the area being treated can become red and irritated within weeks after beginning treatment; the area may become dry, and peeling may occur. Avoid creams and lotions that contain harsh chemicals, to prevent the irritation from spreading.
Esophagitis
Inflammation of your esophagus and mucous membranes can occur if you receive radiation treatment in your chest/lung area. This can cause throat soreness, coughing and difficulty swallowing. These effects usually subside a few weeks after treatment.
Blood Count
People rarely develop a low blood count, or low levels of platelets. This effect is more likely to happen while receiving chemotherapy in addition to radiation treatment. A low blood count may delay your treatments.
