Researchers say at least 170,000 cases of these types of skin cancer can be linked to tanning beds every year.
The British Medical Journal report finds those who use indoor tanning are 67 percent more likely to develop what's known as squamous-cell and basal cell carcinoma.
The risk was highest for people who started using indoor tanning before the age of 25.
Researchers stress, while non-melanoma skin cancers are less deadly, their impact on health is enormous.
