Side effects of radiation therapy are skin problems, such as dryness, itching, blistering, or peeling. These issues usually resolve a few weeks after treatment has finished. If skin damage from radiation treatment becomes a serious problem. Another common side effect is fatigue (a persistent sense of tiredness or exhaustion). Fatigue associated with cancer treatment is different from fatigue from lack of sleep; it is a feeling of exhaustion that does not improve with rest. Although most side effects go away after radiation therapy has finished, some long-term side effects may occur months or even years after treatment ends. These late effects may include developing a second cancer. However, the risk of developing a second cancer because of radiation therapy is low, and this risk is generally outweighed by the benefit of treating the primary, existing cancer. Regards DR DE
