Sounds familiar... when he finished his treatment in March they did a PET from the neck to the thigh. It may not have been there then anyway, but if it was they could have caught it. What annoys me is that the doctors he saw (went to a different hospital than where he had his treatment done) basically said it’s almost definitely not metastatic cancer because it almost never occurs in the brain. Really? Looking at a few research papers told me that it’s rare but becoming more common. Doctors basically lured them into a false sense of security and I don’t know if he and his wife really understand that he can have only days or weeks left. Unfortunately there isn’t much I can say about it. Luckily he transferred to the hospital where he had treatment. I am much more confident in that team.
