Bladder cancer. Radical cystectomy in Sept. '18. No mention of less frequency of scan over time.

Hi! I was diagnosed with base of tongue, left tonsil, and oropharyngeal wall cancer and 2 lymph nodes in January 2019. I had robotic surgery and lymph node removal in February and then I had a scan that showed that it looked like cancer was gone except there was perineural invasion so i did 6 weeks of radiation treatment. I was done with that at the end of April, then I had a follow up PET scan 3 months later, in late July. The scan looked good but a follow up scan was set up for 3 months from that. They set me up for just a CT scan and appointment with my radiation oncologist and I go this Wednesday Nov. 6. I believe he had said that if this scan looked good, that I would go back one year from now for another PET scan, then 2 years from that have 1 more.
