collection of tissue, blood, and cells to be used for studying the causes, prevention, diagnosis, and treatment of breast cancer

Conditions: Breast Cancer

Summary: the purpose of this study is to collect a blood sample from patients with breast disease (cases) and from individuals without breast cancer (controls)that may be used for research purposes. these blood samples will be used by researchers at memorial sloan-kettering cancer center who study the causes of breast cancer, as well as more effective ways to prevent, diagnose, and treat breast cancer.
