Testing for the gene isn’t really necessary. If you have dysplastic nevi, then it is best to get whole body photography to keep track of your moles and look for any changes. This is usually a familial thing but not necessarily genetic. If it changes how you do things, then by all means you can look into the testing but very few centers have the ability to do so. Your family could also have a history of summers at the beach and fair skin, this makes family members more likely to have skin cancer. Hope this is helpful to you,.
Thanks worrywort. Just out of curiosity, did you use tanning beds. Unfortunatley, I was young and stupid…and did quite often. Also, what did your insitu look like? Mine looked like a regular mole, not really anything funny about it. When they called me in to talk about my results, I honestly had in mind that it was a different one from a different removal. So scary.
