Well- we went to oncologist today and he was lovely. Revealed that my dad had had two non invasive tumors removed 4 years ago (dad didn't remember) and all clear in 2017, but this was larger, aggressive and invasive tumor. Dad had ignored symptoms for a while as his heart meds were also causing bleeding so a perfect storm of stuff. No cure for this that would be safe and I respect the doc for being so honest and not pushy about challenging treatments. He could try immunotherapy infusions ( which confused the heck out of my dad. ) Would involve getting a PET scan to have a baseline ( that frightened him as he is afraid he is going to obsess about cancer everywhere.) Then monthly infusions with regular scans to make sure they are working- which there is a 30 % chance of. My dad felt very frustrated by that (and has a hard time getting around) so asked if he could do nothing. It is quite amazing to watch your dad accept this diagnosis and I am still crying. He is going to meet with oncologist again in a month, hopefully with my mom and check in. I go back and forth, but I see how weary he is of trying to stay alive for what is becoming an increasingly hard life. My lovely mom is heartbroken, but there for him.
