Oral Contraceptives Increase Risk For Breast CancerA meta-analysis reported in the recent issue of Mayo Clinic Proceedings indicts oral contraceptives as putting premenopausal women at significantly increased risk for breast cancer, particularly women who use them previous to having a child.
The meta-analysis builds on a number of studies with similar findings. But even as the findings stack up, a number of women are unaware of the risks posed by oral contraceptive use previous to pregnancy,........Go to the Breast-cancer-blog (Added on 10/30/2006 5:48:17 PM)
How Multiple Copies Of A Gene Affect Metastasis?Scientists at UT Southwestern Medical Center have for the first time described how multiple copies of a gene are responsible for metastases in early-stage breast cancer and poor prognosis for patients.
