Dude I'm sorry to hear that. That was pretty much the same scenario as my mom-- everything looked clean on the Pet-Scan and when they opened her up they found micro-tumor everywhere. One minute we were celebrating and the next we were being told she had maybe a few months left. I've never felt so instantly sick in my life.. My only suggestion at this point is to take as much time off of work as possible and spend it with your dad. When I got the news about my mom I was knee deep in planning our imminent office move (whose failure would have resulted in my termination) and I didn't take as much time off of work as I would have liked, mainly visiting an hour each night after leaving the office. Since she died the guilt over not seeing her enough tortures my soul on a daily basis.My dad found out he has Asophygeal Cancer last summer. His last round of chemo ended late last year, and they successfully shrunk the tumor to 2cm, and gave the go-ahead for surgery. Queue dicking him around between the two surgeons needed for the tumor removal and Asophygeal repair. They finally got him in yesterday, did a pet scan of the area - which was clear - and opened him up for the surgery. The surgeon puts the scope in and finds tumors all over the abdominal wall. They close him up and decide to keep him over night. Not a single fucking doctor came up to see him. Not a single fucking one, and nothing was written in his chart. What the actual fuck.
