is it healthier to eat no meat?

Anemia caused by a lack of iron is rare. Anemia is a lot more easily caused by Vitamin B6 or Vitamin B12 deficiency. Have you checked those?

Well, yeah, heme iron is not the only thing in diet that's linked with breast cancer. Estrogen (found in cow's milk) and phytoestrogen (found in soy milk) are also linked with breast cancer. But the link between heme iron and colon cancer seems to be rather strong.

Actually, yes, I have been to doctors and had all the tests.  I take B Vitamins and I take an iron supplement.  This has been a lifelong issue.

My particular breast cancer was NOT hormone driven according to the doctors.  It also was NOT genetic though my mother had it also....a different kind...but that was tested too.

I saw real doctors at a research hospital/university.

As far as I know, most iron supplements are entirely heme iron. So taking them is worse (when it comes to cancer) than eating red meat, since only about 20% of iron in red meat is heme iron (the rest is the good free iron).
