Breast Cancer Decline Tied to Hormone Drop

Posted Apr 19, 07 9:05 AM CDT in World,  US,  Science & Health 

(Newser) – Researchers are linking a dramatic drop in the number of breast cancer cases to the decline in estrogen consumption by menopausal women. Women dropped hormone replacement therapy en mass after a 2002 study tied it to breast cancer risk. Other scientists argued that the decline—about 16,000 fewer new cases per year—may have other causes.

 "This is colossal," said Rowan Chlebowski of Harbor-UCLA Medical Center. "It translates into thousands of fewer breast cancers." The theory is that the hormones may essentially throw gas on the fire of estrogen-related tumors. Without the treatment, they may never grow. A similar study in the U.K. recently linked hormone therapy to ovarian cancer.

But their chance of a stroke, heart attack, or blood clot fell to normal levels after halting the therapy, Reuters reports. More »

    Hormone Therapy Skews Diagnosis Women who use hormone replacement therapy to combat menopause symptoms are more likely to get false mammogram results and have unneeded biopsies, new research shows. The UCLA analysis of an earlier study of more than 16,000 women found that 35% of those on hormones received skewed test results, as opposed to 23% of women on a placebo, Reuters reports. More »

The findings could lead to changes in screening, the San Jose Mercury News reports. In the survey of 3,181 women with breast cancer, 16.7% of black patients under 35 and 3.5% of Hispanic patients had the mutated gene, compared with 2.2% of white patients. More »
