Breasts contain glandular, connective, and fat tissue. Breast density is a term that describes the relative amount of these different types of breast tissue as seen on a mammogram. Dense breasts have relatively high amounts of glandular tissue and fibrous connective tissue and relatively low amounts of fatty breast tissue. Oct 03, · Women who have dense breast tissue have a higher risk of breast cancer compared to women with less dense breast tissue. It’s unclear at this time why dense breast tissue is linked to breast cancer risk. Dense breast tissue also makes it harder for radiologists to see cancer. On mammograms, dense breast tissue looks white.
Extremely dense: The breasts have a lot of fibrous and glandular tissue. This may make it hard to see a cancer on a mammogram because the cancer can blend in with the normal tissue. Still, no one method of measuring breast density has been agreed upon by doctors. Dense breast tissue makes it more difficult to interpret a mammogram, since cancer and dense breast tissue both appear white on a mammogram. Very dense breasts may increase the risk that cancer won't be detected on a mammogram.
Oct 24, · Breast tissue extends from the breastbone near the middle of the chest all the way to your armpit area. The lymph vessels of the breast drain excess fluid and plasma proteins into lymph nodes. Most of this drainage goes into nodes in the armpit. The rest goes to nodes located in the middle of the chest. Dense fibrous tissue would mean non-uniformly dense breast tissue. Such densities make the mammogram difficult to read or to palpate a definite lump on physical exam. The dense tissue makes it more likely that a cancer might be missed. The density finding itself is not a risk factor for breast cancer; many women have these changes.
