What Type Of Skin Cancer Is Most Triggered By UVA Exposure?

Most skin cancers are a result of exposure to the UV rays in sunlight.

Both basal cell and squamous cell cancers (the most common types of skin cancer) tend to be found on sun-exposed parts of the body, and their occurrence is typically related to lifetime sun exposure.

Which is more harmful UVA or UVB?

UVA light, also known as long-wave light, accounts for about 95% of the UV light that reaches our skin. Although both UVA and UVB are bad for skin, UVA rays are more of a threat because a much larger percentage of them reach earth’s surface.

Does UVA or UVB cause skin cancer?

Most tanning beds give off large amounts of UVA, which has been found to increase skin cancer risk. UVB rays have slightly more energy than UVA rays. They can damage skin cells’ DNA directly, and are the main rays that cause sunburns. They are also thought to cause most skin cancers.

What are the 3 most common skin cancers?

There are three major types of skin cancers: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma.

How deep does UV light penetrate skin?

Penetration of human skin by ultraviolet light. The longer the wavelength of light, the deeper the penetration of the light into the skin. Ultraviolet light is generally divided into ultraviolet C (200 to 280 nanometers), ultraviolet B (280 to 320 nanometers), and ultraviolet A (320 to 400 nanometers).
