Skin cancer is the abnormal growth of skin cells- most often develops on skin exposed to the sun.Skin cancer can be cause by the UV radiation from the sun coming in contact with your skin. Sunscreen acts as a protective layer between your skin and to some of the UV radiation the sun admits. It helps block the negative effects that UV radiation can cause on our skin cells. In a recent study it was shown that people with the red hair gene along with the pale skin and freckles gene are more likely to develop skin cancer due to a larger amount of genetic mutations. The red hair variation of the
MC1R gene had 42 percent more mutations than those without the red hair gene.This difference in percentage between those with these genetic mutations and those with out would be equivalent to an extra 21 years of exposed sunlight. Redheads who also have pale skin and freckles have two copies of the MC1R gene whiles non redheads who are pale skinned and have freckles only have one copy. Those who only have one copy are also at an increased risk for developing skin cancer. 400 people's DNA, who have tumors, were sequenced and it was found that just having one copy of the MC1R gene increased the genetic mutations greatly. In the future more studies will be run to try and lessen the risk for developing cancer for these people with the copy of the MC1R gene. About 2 percent of the world are redheads meaning there are a lot of people at risk for developing skin melanoma, one of the most fatal types of cancer.
