I was just diagnosed with a very large tubulovillous mass. Tubulovillous can be low grade (slow growing) or high grade (fast growing). They are always precancerous. I'm having a colon resection next Friday just to be sure there isn't malignant cancer deeper down and it will eventually turn to cancer if I do nothing. Plus they need to remove my lymph nodes just in case. Please advocate for yourself or sign a release so someone can do it for you. Tubulovillous are very serious. Best of luck to you.
