Studying Normal Breast Tissue and Cancer Risk
Breast cancer is the most common cancer among women in the United States. Breast cancer research has been hampered by the difficulty in collecting normal breast tissue. In this study, researchers will obtain samples of normal breast tissue from organ donors and will collect risk-factor data from next-of-kin.
The purpose of this study is to learn how normal breast develops and responds to stresses that are known to increase a woman s chance of developing breast cancer.
Following the breast-tissue donation from 20 volunteers, surgical technicians will make small incisions in the skin and tissue of the breast and remove several samples measuring about one-inch. Technicians also will take samples of the uterine lining to estimate the date of the last menstrual period. The tissue will then be sent to the National Cancer Institute for laboratory research studies. Steps will be taken to ensure that the identity of the participants remains confidential.
