Some states offer women dense breast notifications that are meant to explain that dense breasts are risk factors for breast cancer and can hide cancer on mammograms, and to identify appropriate supplemental screening options. But recent research found that this information is often not easy to read or understand, which questions the usefulness of the documents. (6/7/16)

In almost half of the states in the U.S., some or all women receive a dense breast notification (DBN) with their screening mammograms. But do women understand what these notifications are trying to say?
Information that is difficult to read or understand may fail its purpose to inform women about dense breasts, whether they may have them, and important alternatives to mammograms.
This research indicates that dense breast notifications, while informative, are difficult to read and understand. Women who have any questions about their DBN or screening results should never hesitate to contact their health care provider for clarification, because it is important that all patients understand information that is presented to them.
Laws on breast density notification vary by state.
The National Comprehensive Cancer Network (NCCN) has a panel of experts who develop guidelines on breast screening. With regards to dense breasts and screening, NCCN guidelines state the following:
The following breast cancer screening clinical trials are currently enrolling participants:

Dense breasts can hide cancer on mammograms, and they are a risk factor for cancer. Because of this, almost half of U.S. states include information on dense breasts with mammogram results, because it can help women make informed decisions about what to do next.
Nancy Kressin and her colleagues from the Boston University School of Medicine published a letter in the journal JAMA regarding their efforts to determine whether information included in DBNs is readable and understandable.
The researchers studied the dense breast notifications from all states that issue them. They assessed content, readability (using two tests that measure the reading grade level of text) and understandability (using the Patient Education Materials Assessment Tool that measures patient understanding).
While this study focused on the text included in dense breast notifications, it did not have any data on related outcomes. Did the women from states with dense breast notifications have less anxiety or more cancer detected? So while the researchers know about the readability and understandability of dense breast notifications, they do not know how these factors affect women after they receive their mammogram results. Further research is needed to determine whether the current low reading level of dense breast notifications improve a patient’s ability to make decisions about breast cancer screening.
This study indicates that the reading level of dense breast notifications is too high, making them hard to understand. Another study is needed to see the effect this has on outcomes, but as the study authors wrote, “Efforts should focus on enhancing the understandability of dense breast notifications so that all women are clearly and accurately informed about their density status, its effect on their breast cancer risk and the harms and benefits of supplemental screening.” If dense breast notifications are hard to read and understand, women may glance over and disregard the information, even though it is information that they should know about themselves. If a patient is having difficulty understanding her dense breast notification or any screening result, she should not hesitate to contact a health care provider for further clarification.
It is important to remember that dense breasts are just one indication for increased breast cancer screening. Women with a family history of cancer, a mutation in BRCA1/2 or other gene that increases breast cancer risk, or a personal history of breast cancer should discuss appropriate breast cancer screening with their health care providers.
