But why? You hear about the dangers of UV exposure all the time, but today we\u2019re going to look at the root causes<\/em> behind the damage.<\/p>\n

Let Associated Dermatologists<\/a><\/u> help you get to know some important facts about this main factor that causes<\/em> skin cancer<\/strong>. We\u2019re a group of local dermatologists proudly serving Birmingham, Alabama and the surrounding areas.<\/p>\n

What is UV Radiation?<\/h2>\n

A form of electromagnetic radiation primarily from the sun. Although there are also several man-made sources such as tanning and welding torches, sunlight is the main natural source of UV rays.<\/p>\n

What types of UV rays cause skin cancer?<\/h2>\n

 <\/p>\n

UVA Rays<\/h3>\n

UVA rays penetrate deeply<\/em> into the skin and that causes skin-aging in the form of genetic damage to the cells. This is the type of UV rays that are responsible for long-term skin damage such as wrinkles, blotchiness, and skin cancer. Tanning beds give off large amounts of UVA which is proven<\/strong> to increase the risk of skin cancer<\/a>.<\/p>\n

UVB Rays<\/h3>\n

The main cause of sunburns are the UVB rays which are a significant risk factor for skin cancer. This type has slightly more energy than UVA rays. UVB exposure can damage skin cells\u2019 DNA directly because the rays penetrate into the epidermis or the top layer of the skin.As mentioned above, both types of UV rays damage the skin and cause skin cancer<\/strong> but UVB rays, are the more potent cause of at least some skin cancers. But still, there are no safe UV rays.<\/p>\n
