Breast density knowledge and willingness to delay treatment for pre-operative breast cancer imaging among women with a personal history of breast cancer

Following a breast cancer diagnosis, it is uncertain whether women’s breast density knowledge influences their willingness to undergo pre-operative imaging to detect additional cancer in their breasts. We evaluated women’s breast density knowledge and their willingness to delay treatment for pre-operative testing. We surveyed women identified in the Breast Cancer Surveillance Consortium aged ≥ 18 years, with first breast cancer diagnosed within the prior 6–18 months, who had at least one breast density measurement within the 5 years prior to their diagnosis. We assessed women’s breast density knowledge and correlates of willingness to delay treatment for 6 or more weeks for pre-operative imaging via logistic regression. Survey participation was 28.3
