回答: Are you sure it's not the increased uv exposure264849152014-10-02 13:48:21
Why are melanoma rates increasing?
Some people are not protecting themselves from sun exposure while others subject themselves to ultraviolet (UV) radiation from indoor tanning beds and lamps. In fact, nearly 28 million people tan indoors in the United States annually.5,6 Nearly 70 percent of tanning salon patrons are Caucasian girls and women, primarily aged 16 to 29 years, which Dr. Rigel says may explain why the torso is the most common location for developing melanoma in females 15-29 years old.7,8 Depletion of the ozone layer may contribute to the increase in melanoma incidence because it allows more UV radiation to reach the earth's surface.

Will melanoma rates continue to rise?
Dr. Rigel says melanoma rates will continue to rise as long as people continue to receive excessive UV exposure from the sun and tanning beds. However, he believes that without efforts to educate people about the importance of sun protection, the increase would be much worse.
