Skin Cancer

Skin cancer, although it seems small, can be quite deadly if it is not caught on time. As for how it develops, the cancer develops when DNA is damaged beyond repair. The cells that are damaged then grow and divide at a rate that is uncontrollable. When this damage occurs in the skin and the cells grow and divide uncontrollably, skin cancer is the result. The damaged cells will continue to multiply and that will cause a tumor.

The cancer usually develops in the epidermis, which is the outermost skin layer. That is why the skin cancer tumor is usually quite visible. This is why skin cancer is usually detectable in the early stages.

Sun exposure seems to be the main reason why skin cancer develops. The American Cancer Society has stated that most of the 1 million cases of skin cancer that are diagnosed each year could be prevented with proper sun ray protection. It is the UV rays from the sun that causes DNA to become damaged. The body is such an amazing machine that it can usually repair this DNA damage, but there is a time in which that repair may not take place. Cumulative sun exposure can cause this and later lead to skin cancer. This is why some individuals do not develop skin cancer until 30 or 40 years after they have had the extensive sun exposure.
