Elgie Recently had his 6 month well he went way over his 6-month but anyway he had his F18 PET scan. His results came back as increased activity in the left humeral head. So now we have to schedule an MRI of the left shoulder area to see what that says. I was in the understanding that the F18 was the best detector of cancer. I guess I was wrong and now we have to wait to get this next scan and results. I believe it has been over two years since any increased activity. No changes in scans until this.
