I started chemo (12 sessions plus 2 days on chemo pump after each session) and radiation (6 weeks every day) treatment shortly after diagnosis, starting in November 2022. After that treatment my surgeon performed a colonoscopy and said that he can't see any signs of cancer. I have to check again in 5 weeks but it seems that the treatment worked. It was the best news that I have ever received so here's hoping that I get the same result in 5 weeks time.
