why high spf sunscreen after radiation therapy
Skin in an area that's receiving radiation therapy should be protected from the sun with a bathing suit or other clothing, since the skin may already be red or burned from the treatments. It's also important to use sunscreen. Sunscreens work in different ways.Chemical sunscreen absorbs ultraviolet light before it can harm the skin. Chemical sunscreen acts as a filter and does allow some radiation to get through, which is why tanning is still possible.ut too much sun exposure can be dangerous. It can cause skin cancer, cataracts, wrinkles, and painful burns that may permanently damage skin. It can also make side effects of some chemotherapy worse.
