Dense breasts have high proportions of fibrous or glandular tissue and relatively little fat. There are four categories for breast density: almost entirely fatty, scattered fibroglandular density, heterogeneously dense and extremely dense. If you are diagnosed with heterogeneously dense or extremely dense breasts, you’ll want to talk to your physician about your options for breast cancer screening, Hungerford says.
“Breast density may vary over time and therefore you may have a mammogram one year that describes your breasts as heterogeneously dense and a mammogram the next year which describes your breasts as extremely dense,” Hungerford says. “The density of breasts is influenced by many factors including diet, weight loss and gain, hormones and age.”
If you are concerned about any aspect of your breast health, you should talk to your physician, he said. It’s important to discuss your risk of breast cancer to determine the screening options that are right for you.
