Day 0 - Before Efudex

This is what I look like before the Efudex treatment:

Area where I previously used Efudex

This is the AK on my left cheek that I hope will "light-up" and be destroyed by the Efudex. There is a small keratin pillar or horn that grows out of the red patch for a few months, then dissappears to be followed by another one in a different location within the patch. Two attempts to freeze it with liquid nitrogen failed. The cat came back after each attempt.
