I just looked up Carac and it says it is the same as the effudux? Maybe just a different name?? I think I am going to suggest trying Effudux for this next round of spots-5. I want to get them biopsied first so I know what I am dealing with. I have been diagnosed with the morpheaform infiltrative type of bc on my brow. I have read that these creams are not good for this sub type. Anyway, it scares me a bit to just be applying lotions like aldara etc when I have no idea what I am dealing with. The Aldara also seems to work well once the spot has been biopsied then healed up-i/o of the surgery route.
