January 24, 2023 – Dense breast tissue is related to a better risk of breast cancer – as much as 4 times higher – but in a recent study, most girls didn't see it as a major risk in comparison with other aspects.
More than 1,850 women between the ages of 40 and 76 were surveyed about their risk of breast density in comparison with five other aspects: having a first-degree relative with the disease, being obese, drinking alcohol, not having children and having had a previous breast biopsy.
“Although breast density is associated with a 1.2- to 4-fold higher risk of breast cancer, few women perceived breast density as a strong personal risk factor,” says the study, which was published in JAMA network opened.
Women perceived family history – which may double the chance – as a greater risk factor. And respondents mostly saw no solution to reduce their risk, regardless that physical activity and low alcohol consumption reduce the chance. CNN reported.
The women within the study had no history of breast cancer and were aware of breast density, which refers back to the indisputable fact that the breast is made up of more glandular and connective tissue than fat. Density changes throughout life and is often higher when women are younger, have a lower body weight, are pregnant or breastfeeding, or are taking hormone substitute therapy.
“What we learned from this study is that we need to do a better job of educating not only the general public of women, but also the general public of health care providers who are providing primary care and ordering these screening mammograms,” said Dr. Ruth Oratz, a breast cancer oncologist at NYU Langone Health who was not involved within the study.
Most women between the ages of fifty and 74 are strongly advised to have a mammogram each one to 2 years. For women with higher breast density, additional screening could also be useful, the study authors write.
