Breast Density Knowledge and Awareness: A Review of Literature

We reviewed the literature on breast density knowledge and breast density awareness to explore what challenges are faced by this area of research.

A review of PubMED, PsycINFO, and CINAHL databases was performed. Studies were published in peer-reviewed journals (in all years available) and written in English. The broad search terms used were ["breast density"] AND ["knowledge" OR "awareness"]. Eligible articles were included in the final analysis after meeting the following inclusion criteria: (1) the records had to quantitatively examine and report breast density knowledge and awareness, (2) the number of participants in the sample had to be clearly specified, and (3) studies reporting differences in breast density knowledge and awareness between racial and ethnic groups were included in the review.

Of the 277 articles identified, only 5 met inclusion criteria and addressed breast density knowledge and awareness. Characteristics of studies and results were examined.

There is insufficient evidence to determine a pattern of breast density knowledge and awareness in women. More quality studies are needed that focus on how well women understand the relationship between breast density, breast cancer risk, and breast cancer screening, especially in diverse populations.
