I'm just gonna add: If there's an insurance company unwilling to pay for adjuvant (post-op) chemo, they'd better be willing to pay for monthly MRI and PET scans for at least a year, along with monthly Signatera tests and biweekly CA19-9 tests instead.

Although the idea of "Total Neoadjuvant Therapy" has some science to support it, I think more science will overturn that down the road. A lot of the "best science" during the first few weeks of the covid pandemic turned out to be a crock. Lobotomies and electroshock therapy were common treatments for mental health issues back in the dark ages as well.
