title: Benign and malignant breast pathology.
abstract: Research is focused on defining high-risk factors associated with the development of breast cancer and occult metastatic disease in node-negative patients. The interaction between hormones and growth factors is being diligently investigated, both in the genesis of breast cancer and in metastases. The effect of oral contraceptives on breast pathology remains under close scrutiny. Screening mammography for young women is proving to be of doubtful value.
