I just had my 2nd surgery for skin cancer and my first one with the type you mentioned. I'm 7 years post Heart transplant and I'm on Tacrolimous 1.5 mg twice a day. I'm told that skin damage and cancers actually start on our youth. But are kept at bay by our immune system. So it's super important to wear sunscreen being we are immune suppressed due to transplant. So I know for me they watch my levels very closely as they keep them.as.loe as possible to help my immune system be as useful as possible. Quite the balancing act. But for me it works. I'm also checked for skin cancer every 3 months. Hope that helps.
