ABILENE, Texas -

A warning posted by the Surgeon General Tuesday says there has been a 200% increase in melanoma cancer cases since 1973.

The deadly skin disease is often found in those that tan indoor, as well as outdoor.

"We just tend to put our priorities to what we think is looking pretty," said Linda Neill, Manager of Educations Services at Hendrick Cancer Center, "looking beautiful compared to our health, and our health is really the one that's suffering."

A Skin Cancer Foundation study also says that in the U.S., there have been more skin cancer cases due to indoor tanning, than there has been lung cancer cases of those who smoke.

"Any kind of tanning is not safe, " says Neill. "If you're gonna be outdoors, make sure you have a good broad spectrum sunscreen on, at least SPF 30 and re-apply it every 2 hours."

Neill also says other tips to preventing the cancer are covering your skin from direct sun, wearing hats, and wearing glasses.
