ScienceDaily (Mar. 2, 2010) — An eight-year prospective study of more than 30,000 postmenopausal Swedish women found that those who were using or had used HRT had significantly higher rates of cataract removal, compared with women who had never used HRT. Alcohol consumption seemed to increase HRT’s harmful effect. The HRT study was led by Birgitta E. Lindblad, MD, Sundsvall Hospital, Sweden as part of the Swedish Mammography Cohort (SMC), established to study lifestyle factors and chronic diseases.
