Hi, Thanks for writing in. There is a possibility of tanning beds causing cancer of the skin. A link connecting papillary carcinoma thyroid to tanning beds is uncomfirmed. However, I have come across patients who spent a lot of time on tanning beds for years and have developed papillary cancer thyroid. The original researches show tanning to be an underlying cause of melanoma which is a violent form of skin cancer. There is also a particular type of melanoma involving the eyes called occular melanoma and many patients admit to having spent years using many years on tanning beds under the sun therefore making it a cause. Please do not worry.
