How does the sun cause skin cancer?

Answer 1

The sun emits harmful ultraviolet radiation especially during its peak which is between 10AM to 4PM. Being exposed to it frequently and for long periods damage your skin cells and worse, kill them, leading to chronic skin conditions such as sunburn. These skin conditions give rise to skin tumors to develop.

Answer 2

I'm not sure of what the answer is because I myself am looking for it.The ultraviolet (UV) component of sunlight can damage the skin, altering its cell coding. Then the cells can start reproducing erratically, which is cancer. Direct UV radiation is worse than reflected UV because of the intensity, but reflected UV is still a danger nonetheless. A good sun block will cut the risk of UV caused skin cancer.

Answer 3

Most damage is caused by ultraviolet light (UV)

it comes down to the fact that UV light has a relatively high energy (due to shorter wavelength than visible light).

when a photon from UV light hits cells in your body it causes damage, either by "breaking" DNA molecules or doing damage to other molecules that in turn cause damage to the DNA molecules.

This damage to the DNA results in it not functioning properly, which may lead to cancer. The same sun rays that tan you (UV rays) cause the genes in your skin cells to mutate. The mutated cells are called cancer cells.

Answer 4

ultra-violet rays cause skin cancer
Most times, it is caused by excessive sun exposure.

Answer 5

Sun exposure causes skin cancer because the ultraviolet radiation damages the genetic code in some skin cells that are exposed to strong sunshine, this may lead to skin cancer.

Answer 6

Not enough sunlight can cause cancer,

IF THIS HELPS ADD 2 MY POPULARITY :)

Answer 7

if you stay out in the sun for extensive amounts of time if you just spend the summer at the beach its fine
