What is Breast Cancer? (revised)

This pamphlet, written by the Vancouver Women's Health Collective (VWHC), describes and defines cancer, theories of causation, types of breast cancer, and rates of breast cancer in women in North America. It also describes the stages of breast cancer progression, theories of risk, and possible causes of breast cancer such as dietary fat, body hormone levels, hormonal drugs, and family history, among others. The pamphlet is written in accessible language and is cautious about making any concrete conclusions about causation, pointing to inconclusive and contradictory research results.
