Skin cancer risk

Look beyond the sun for skin cancer culprits, doctors warn

I was a bit surprised at the size of the risk increase:

Even things that seem unrelated to UV light—such as getting an organ transplant or a tattoo, or having an autoimmune disease—have been linked to skin cancer diagnoses.

People who've had an organ transplant have an extremely elevated risk for skin cancer—up to 200 times higher than others, according to Ibrahim. 

This stems from the medications that must be taken after a transplant to suppress the immune system. As a result, the immune system, which normally fights off growing cancer cells, may not be strong enough to do its job.

Organ transplant recipients should talk to a dermatologist to get an idea of their baseline risk for skin cancer and find out how often they need to be screened. Ibrahim said that some high-risk people who've had organ transplants need screening every three to four weeks.
