UV radiation is part of the natural energy produced by the sun. On the electromagnetic spectrum, UV light has shorter wavelengths than visible light, so your eyes can’t see UV, but your skin can feel it. Tanning beds also emit UV radiation.

While UVA and UVB rays differ in how they affect the skin, they both do harm. Unprotected exposure to UVA and UVB damages the DNA in skin cells, producing genetic defects, or mutations, that can lead to skin cancer and premature aging. UV rays can also cause eye damage, including cataracts and eyelid cancers.

Good Morning America host and weather anchor Sam Champion is no stranger to skin cancer. After his first bout with the disease at age 26, Sam has had multiple skin cancers removed and is familiar with the warning signs of the disease. But even he was surprised by the appearance of his most recent basal cell carcinoma (BCC), so he’s speaking up about the importance of regular skin exams, getting to know your skin and trusting your instincts.

Understanding UV radiation and how it damages your skin is an important first step in  safeguarding yourself against skin cancer.

UV exposure that leads to sunburn has proven to play a strong role in developing melanoma, a dangerous type of skin cancer. Research shows that the UV rays that damage skin can also alter a gene that suppresses tumors, raising the risk of sun-damaged skin cells developing into skin cancer.
