What effects does radiation have on skin and fingernails?
Skin can become dry and sensitive from radiation. To help prevent dry or itchy skin, take warm (not hot) showers or baths. Hot water can dry your skin. Lubricate irritated areas with a water-based moisturizer and use a lubricating soap. Be sure to use sunscreen with at least SPF15. Radiation therapy causes your body to make more melanin, and your skin may become darker in the treated areas only. This is a temporary condition.
