Radiation therapy, also known as radiotherapy, is a cancer treatment that uses high-energy particles such as X-rays, gamma rays, or photons to destroy cancer cells and early-stage malignant tumors. In fact, over 50% of patients usually undergo radiation therapy as part of their cancer care. However, just like all other medications, the therapy has some side effects, including radiation burns and skin irritation (radiation dermatitis). Based on radiation dose, skin type, and the treatment area, skin reactions vary in severity. Most symptoms can be prevented or treated while many subside on their own after the treatment ends.
If you are receiving radiation therapy, you must disclose the details about your preexisting medical conditions and any chronic habits that you may have, including diabetes, hypertension, anemia, skin cancer history (in the treatment area), and smoking, as they affect how your skin reacts toward radiation therapy, interrupting the treatment gradually.
