Due to life long sun exposure and fair skin, I am prone to developing AKs (pre-cancer spots), SCC (squamous) and BCC (basal). I had all 3 prior to starting brinsupri, and one after being on brinsupri for 6 months. Each time I get a skin check the dermatologist sprays/freezes at least 20 different spots on my body it seems. There's one spot that has been recalcitrant so at times I've been rechecked every 6 weeks. Fortunately, they are slow growing so I keep an eye on suspicious areas and use FU5 cream at home. If you can have them checked/frozen before they advance is key.

Brinsupri is not a miracle but has helped enough that I do not want to discontinue it. The frequent skin checks are the trade off.
