No More Breast Cancer is the UK Working Group on the Primary Prevention of Breast Cancer's online resource based on the report, Breast Cancer: an environmental disease, offered as a public interest resource focusing on risk factors for breast cancer not recognized as part of the UK’s cancer prevention agenda. The report can be used by individuals and groups planning or developing primary prevention campaign work and as a general reference for anyone concerned about breast cancer prevention, or disease prevention in general. In addition, the report can be adapted for use in countries other than the UK, among organizations interested in the environmental issues of cancer prevention.

Breast Cancer: an environmental disease report document challenges a number of prevailing views and attitudes about breast cancer and sets out to establish a new view of breast cancer as a preventable rather than inevitable disease. The purpose of the UK Working Group on the Primary Prevention of Breast Cancer is in addressing the environmental factors, as opposed to lifestyle factors, associated with breast cancer. To inform and encourage new ways of thinking about this disease and the many possibilities for its prevention, and challenge the UK government to prioritize prevention as the primary goal.
