Hormone replacement tied to lung cancer risk
February 24th, 2010
Women who use hormone replacement therapy combining estrogen and progestin may have a higher risk of lung cancer than non-users, a new study finds.
Whether hormone replacement therapy (HRT) itself is to blame is not certain, researchers say. But the findings add to the complicated mix of potential health effects of HRT.
The study, published in the Journal of Clinical Oncology, looked at new lung cancer diagnoses among more than 36,000 women ages 50 to 75 who were followed over six years. During that time, 344 women developed the cancer.
