I had colorectal surgery on June 08 2010 T3, had 6 cycles of chemo Last chemo was on 3rd Dec and Xeloda tabs on 10th Dec. On 29th dec saw blood in my stools, next day it stopped and recurred on 10th Jan 2011 again, my doc prescribed med for 5 days CIPLOX TZ, it stopped for a few days but now i can see specks in my stools, sometimes it is there, sometimes not, had a CT scan done, flexible sigmoidoscopy which was clear, so what is the blood due to, i have no pain or discomfort, can you enlighten me
