New Study Firmly Ties Hormone to Breast Cancer

It is clear that breast cancer rates plunged in recent years mainly because millions of women quit hormone therapy and fewer newly menopausal women started on it, said the study’s leader, Dr. Rowan Chlebowski of Harbor-UCLA Medical Center in Los Angeles.

“It’s an excellent message for women: You can still diminish risk (by quitting), even if you’ve been on hormones for a long time,” said Dr. Claudine Isaacs of Georgetown University’s Lombardi Comprehensive Cancer Center. “It’s not like smoking where you have to wait 10 or 15 years for the risk to come down.”

Study results were given Saturday at the San Antonio Breast Cancer Symposium…

The Women’s Health Initiative study had two parts. In one, 16,608 women closely matched for age, weight and other health factors were randomly assigned to take either Wyeth Pharmaceuticals’ Prempro — estrogen and progestin — or dummy pills.

This part was halted when researchers saw a 26 percent higher risk of breast cancer in those on Prempro.

But that was an average over the 5 1/2 years women were on the pills. For the new study, researchers tracked 15,387 of these women through July 2005, and plotted breast cancer cases as they occurred over time.

They saw a clear trend: Risk rose with the start of use, peaked when the study ended and fell as nearly all hormone users stopped taking their pills. At the peak, the breast cancer risk for pill takers was twice that of the others.

Granted this was about Hormone Replacement Therapy(synthetic estrogen and progestine), but still.

The first study of 16,608 by Women’s Health Initiative that they stopped in 2002 because of the increased breast cancer was started in 1991 and cost $625 million.

This study was very extensive but there is very little on the news about it. This was the second study to be stopped.

Now a third study done over the five years of 15,387 women and we see a blip on yahoo news. They want us to be thankful that the bad effects go down and that breast cancer is lower yet no study has been done on long term effects or other pills. Why, because of the politics of birth control?
