Some mammogram reports sent to women mention breast density. Your health care provider can also tell you if your mammogram shows that you have dense breasts. In some states, women whose mammograms show heterogenously dense or extremely dense breasts must be told that they have dense breasts in the summary of the mammogram report that is sent to patients sometimes called the lay summary. The language used is mandated by each law, and may say something like this:
Each breast contains between 15 and 20 sections called lobes, each of which is composed of many smaller structures known as glands or alveoli. These glands produce milk. A system of small tubes known as ducts transports milk from the glands to a big central duct that has multiple openings in the nipple. A central duct opens into the nipple from each lobe. A band of muscle surrounds each gland. Eventually, a sucking baby extracts the milk by pressing and pumping it out from these pools through the nipple.
