The cost of hormone replacement therapy is not in question. Of the 34,433 HRT users, 193 were diagnosed with colon cancer during the study period; that compared with 151 cases among the 13,778 women who had never used hormone replacement. HRT — with either estrogen alone or a combination of estrogen and progestin — was linked to a lower colon cancer risk even when the researchers accounted for the women’s age, weight, exercise levels and race.
