Hi, I've been reading all the messages regarding carac cream. My Dr. has recommended that I use it on my arms. I've had 2 Bowen's and 1 basal skin cancers on my hand and face, nothing on my arms, yet. Has anyone used this on their arms? I don't know if I should do one arm or do both and get it over with? All of the messages I've read have helped me alot. Although none of use wants to do this, we have to. I am going to start the beginning of Oct and would apprectiate any hints. Thanks for any information you can give me.
