However, recently scientist have concluded that dark skin does not offer extra protection against the threat of cancer. Furthermore, it is the belief of science that dark skin actually serves as a `magnet` for harmful UV rays, which in turn increases the risk of contracting skin cancer.

Hispanics are twice as likely as whites, while Blacks are three times as likely as whites, to be diagnosed with skin cancer.

Melanin, a natural chemical found in humans, is more plenteous in dark skin individuals. It is now believed that the high amount of melanin a person has, the greater the likelihood that they may be diagnosed with skin cancer.

It has been reported that more than 70,000 new cases of skin cancer will be diagnosed this year in the United Kingdom. This makes skin cancer the most common form of cancer in that country.
