"Dense breasts" diagnosis varies widely among radiologists

The likelihood of a female being told she has breasts which are thick significantly based on which radiologist interprets her mammogram. These findings, published in Annals of Internal Medicine, have policy implications with regard to supplemental methods that are screening.

Having dense breasts helps it be more challenging to interpret mammography results and is also a danger that is separate for developing breast cancer tumors. To ensure that ladies with thick breasts know about the limitations of mammography and their increased danger for cancer, about half of U.S. states now have breast density notification laws and regulations and some of those continuing states require that women are advised to keep in touch with their own health care providers about supplemental assessment. Such guidelines are controversial due to the large number of females affected and because the lack of opinion in the community that is medical supplemental screening methods. An concern that is additional the subjective nature of breast density assessment, that is based on the Breast Imaging Reporting and information System (BI-RADS) that delivers four feasible groups for breast density.

utilizing information from 30 radiology facilities within the three breast cancer research that is assessment of this Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium, researchers desired to look at variations in the circulation of breast thickness assessment across radiologists as recorded in clinical practice. In addition they accounted for facets known to be connected with breast thickness. The scientists found a variation that is wide radiologists into the portion of mammograms rated as showing thick breasts (which range from 6.3 per cent to 84.5 percent), which persisted after adjustment for patient facets. In addition, significantly more than 1 in 6 ladies with consecutive mammograms interpreted by various radiologists during an interval that is brief reclassified into dense versus nondense groups. In line with the researchers, this variation has implications being important debates about mandatory notification rules.
