We got our pet scan results back today. The cancer is gone from his nasal areas. Yea!!! They said around his larynx and throat it showed a flare up. They told us not to be concerned as it could be irratation from the rads, inflamation or infection. He is going tomorrow for a scope with his ent. So hoping its nothing. I've read so many on this forum not to get to nervous about the first pet scan. so I am hoping to take your advice. The RO doesn't want to see us for 3 months. So I am taking that as good sign.
