That is right - there is an increased risk of non-melanoma skin cancer. There may be an increased risk of melanoma as well, but I'm not sure data are as solid there.

So it's a good reminder that people on these meds should be sun-aware: limit sun exposure, wear sunscreen and sunblocking clothing, hats, etc. And get regular skin checks with a dermatologist.

GI's who put a patient on aza or 6mp, or biologics or other immune-altering meds, should advise patients of skin risks and to see a dermatologist on a regular basis.

Yup a good reminder to folks. Always try to cover up with prolonged sun exposure, but don't have to become a vampire and paranoid or anything. It's a good idea to know what skin cancer looks like, and once or twice a year have a spouse or primary care doctor check your back where you cannot easily check yourself. My primary care doctor does that as part of his typical, annual wellness visits. I've got a lot of flat, dark spots randomly on my skin. If they became cancerous they would no longer be circles/ovals, rather they would have finger like protrusions from the edges.
