question: I had a co;orectal cancer 2 yrs ago and underwent radiation and bracytherapy in th rectal area. I was good for the first 6 months and then I started to bleed more and more. last week I did my CEA reading and no more cancer was apparent. I have however severe anemia and bleed heavily every day. What can that be. Even my dr seems to be confused as we doublted colon cancer but thankfully it is not that.can hemoroids hurt and blled to the point of me having sever anemia. My diet is strickly vegetarian. Thanks Victoria
