The results, from an 11-year follow up with more than 12,000 women who were randomly assigned to receive either the combination hormone therapy or a placebo, found 385 women taking the therapy developed an aggressive form of breast cancer, compared to 293 in the placebo group. Twenty-five women who took hormone therapy died from breast cancer during the study, compared to 12 women in the placebo group. null “It is early in the follow-up and the number of breast cancer deaths will certainly substantially increase as we move forward,” said Dr. Rowan Chlebowski, professor of medicine at the David Geffen School of Medicine at the University of California, Los Angeles, and lead author of the study. Women in the study who used estrogen and progestin for five-and-a-half years — which is considered long-term use of the therapy — were at higher risk of getting breast cancer, said Chlebowksi.

Hormone replacement therapy may reduce pancreatic cancer risk
Because estrogen by itself may increase the risk of uterine cancer, estrogen-only HRT is generally prescribed only to women who’ve had their uterus removed (a hysterectomy). However, in contrast to the results with estrogen-only HRT, the study also found another type of estrogen-containing medication birth control pills were linked with an increased risk of pancreatic cancer when used over the long term. [ 7 Surprising Facts about The Pill ] Women who took oral contraception for 10 years or more had a 72 percent greater risk of developing pancreatic cancer than those who had never used oral contraception. The study found associations, and cannot prove that estrogen whether in hormone replacement therapy or birth control pills actually causes an increase or decrease in pancreatic cancer risk .
