About those scans...

Congrats to you and your dad I would consider those great scans my dad's last scan was better showed no spread but still one annoying mass in the pelvis that oncologist says is cancer radiation oncologist says maybe . So comparing it to my dad's I would say there very good scans . Heck I consider my dad's scans good as long as they don't show spread cause to me thats the huge thing . My dad has a ileostomy bag and one for urine to whatever it's called so he has dealt with what your dad is going threw and still struggles . My advice just be there for him love him other then that they just kind of have to find there way threw the depression . My dad has good days seems to be finding his way threw it I know yours will to . 

P.S Also my dad has had a lung nodule for over a year now and it's never been nothing it's just kind of there idk if that makes you worry any lesst or not but just putting it out there

Since I mention it now and again, and figure it may be of use again down the roard:

"One thing that comes up over and over are scans.  The types, the reports.

As to reading reports in general, each person reading things may see or report different things where they have done studies on this.   They would give someone 50 scans, including duplicates of the same scan, and they would issue two reports.  I have had that with my scans.  Some report some things, some another depending on what the individual reading sees.

I am pushing close to 50 scans in total now.  Not one report is the same in terms of what is mentioned or not mentioned.  One report said no adenopathy, next one said there was, then it was gone.  It did not change.  It just was not reported."

This part is more specific - on the lung nodules they sound small.  So even if there is a worse case scenario that there is cancer (which may or may not be the case as Tru pointed out) it is probably worthwhile to just watch instead of going through a procedure and the rest.  He is being monitered, so the waiting to see changes (if any) in a few months sounds fine.  Plus you have the PET scan.  So you have two ways of looking at it - so the FDG probably would have flagged something.  I have this issue now.  Two new tumors in spine.  Watching and waiting.  Plus trying to determine if an old one is active (or not) or something else is going on from prior radiation.  So I went from being scheduled for radiation for 4 tumors in my spine, to hold off and let's see if it is needed.

For me personally, getting a therapist that I could really speak to freely has made an incredible difference in my day to day. It's all over Telehealth and can do either phone calls or video calls. I also received a low level of antidepressant. Between the two things it has really helped. I simply mentioned it to my oncologist and he prescribed the antidepressant and referred me to a therapist. 

Just chirping in due to the positive impact therapy has had on my life. 

To say the cancer experience is traumatic would be an understatement. 

1.5 yrs  NED and counting .....

The scan results sound good to me, not that I have any qualifications to say that. Scans are written for other doctors, not patients, so they are often hard to interpret.  Life can be very tough, I hope your Dad finds something to cheer him up.  Maybe addressing things directly with him would help?
