The World Health Organization has determined that UV rays from tanning beds cause cancer.
The increased risk of melanoma associated with early tanning bed use is 59% for people whose first exposure to artificial UV rays in a tanning bed occurred before age 35 years and that risk increased with the number of tanning bed sessions per year.
Melanoma kills one person every 50 minutes. It's the second most common cancer for 15-29 year olds.
Tanning beds put out 3-6 times the amount of radiation given off by the sun.
Getting more sun won't increase your Vitamin D level, but it will increase your risk of skin cancer.
