Another study released on tanning dangers

A bit random I know, but I came across another study recently released about tanning dangers. I honestly thought it was common sense that tanning is dangerous until a few weeks ago I saw people posting that you need vitamin D and therefore should go tanning regularly. Yes, you need vitamin D. No, you don't need to tan in order to get it. If you tan, you are 6 times more likely to develop melanoma. 6 FRICKIN TIMES!!!!! I'm watching a friend battle for his life with melanoma right now. It's sadly a battle he'll probably lose. He's never been tanning a day in his life yet he still got it. Oh and he's 30 with a wife and 2 year old.
