Studies have found that melanoma rates in young women have increased manifold in the recent years. A Mayo Clinic study has found that the number of skin cancer cases has increased eightfold between 1970 and 2009.

Here are five factors that increase the risk of skin cancer:

Genetics

If your parents, siblings, or kids have had a melanoma, your risk is 50 percent more than the average person. If more distant relatives have been diagnosed, you are still at risk.

Sunburns

If you have had sunburns, your chances of developing melanoma later in life increase significantly. Studies find that five mild sunburns over the course of your life can also double the risk.

Using tanners

Using tanners can increase the risk of skin cancer. In fact, indoor ultraviolet (UV) tanners are 74 percent more likely to develop melanoma than those who have never tanned indoors.

Fair Skin or Light Eyes

Pale women have less melanin, the skin’s natural sun protection. Those with baby-blue or green eyes are also more prone to skin cancer, especially ocular and eyelid melanomas, than women with deep-brown irises.

Living in a Sunny or High-Altitude Area

Tropical climates expose you to strong UV radiation year-round, says Fields. As for altitude, for every 1,000 feet above sea level, you increase your UV exposure by 4 to 5 percent.
