Unless you're Snooki, odds are you know that using tanning beds is not the smartest choice. But just in case you didn't believe what common sense and past experiences have showed you, here's some more scientific proof for you.

A new study from the Mayo Clinic has found there's large increase in the occurance of skin cancer in adults, ages 18 to 39. The researchers discovered that between 1970 and 2009, cases of melanoma increased eightfold in young women and fourfold in young men. Doctors are attributing this increase to the use of tanning beds, which are a known carcinogen. The data was taken from looked at instances of first-time diagnosis of melanoma in patients.

But, it's not all bad news. The study did show that while more young people are getting diagnosed with melanoma, their chances of surviving it are greater, mostly due to it being discovered earlier.

So, for all of you out there who like to keep it orange, do yourselves a favor and invest in some self-tanner (or better health insurance)
