Hello! Efudex or other chemo creams. 25 yo female w hx of tanning beds and sunburns in a "past life" lol makes me cringe now.. & accidentally burnt my shoulders this past weekend playing kickball (SO unhappy and anxious about this). Have Had 3 MIS's removed, 1 on my shoulder. I haven't yet but I know I will obviously get the AK's and other cancers as I get older. I was wondering if It would be possible to use Efudex Cream on my shoulders now? Will this also help prevent melanoma in situ's? Thank you for any advice!
