A few years ago, the association of decreased AD risk was noted with squamous or basal cell skin cancers (http://www.livescience.com/32042-skin-c ... -risk.html
). However, both of these cancers are precipitated by sun exposure, so it's more likely to be just a Vitamin D connection. Still it's comforting to think my basal cell cancer was linked to a 80% AD reduction. My mom has a history of both these skin cancers. Not sure this relates to the skin biopsy.
