Oh no, Lydia--I'm so, so sorry.
You've just had so much to deal with over the past 5 years. Was hoping maybe we'd both be lucky enough to escape this. I've read that local recurrences have better survival stats than distant metastasis. There's an article at the link below that discusses this. And I agree that you definitely need to get your tumor tested for microsatellite instability, asap! From what I understand, those who are MSI-H have been seeing really good results with immunotherapy.
All that aside, I do believe there are supplements that can lengthen survival and improve your odds, if carefully targeted (things like nattokinase, IP-6, and anti-inflammatories have been particularly helpful for me). My naturopath has been a God-send in this area. It isn't inexpensive and I don't believe I'm out of the woods myself by a long shot, but I know what I take is having an impact because I can see it in my blood work. Please PM me if you'd like more info. Either way you are in my thoughts. Sending you all the positive vibes I can muster!https://academic.oup.com/annonc/article/16/5/756/150213
