Unfortunately, there's not much a woman can do about the density of her breast tissue, the researchers noted. "Treatment with tamoxifen, an estrogen hormone blocker, is the only intervention currently known that substantially reduces breast density, and thus reduces breast cancer risk," Engmann explained.
How often does dense breast tissue turn into cancer?

Factors associated with higher breast density include using postmenopausal hormone replacement therapy and having a low body mass index.
Should I worry about having dense breasts?
Dense breast tissue is common and is not abnormal. However, dense breast tissue can make it harder to evaluate the results of your mammogram and may also be associated with an increased risk of breast cancer.

The accuracy of mammograms increased as women's breasts became fattier and less dense. In young women and women with dense breasts, ultrasound appears superior to mammography, and may be an appropriate initial imaging test in those women.
Can breast density go away?
No — breast density is determined by genetics, age, menopause status and family history. Weight gain and certain medications can also influence your breast density. Though your breast density can't be changed, information is power.
What vitamin helps dense breast tissue?
Several lines of evidence suggest that vitamin D may play a role in breast density and breast carcinogenesis. Vitamin D reduces proliferation and promotes differentiation and apoptosis in breast cells in culture.
Can a radiologist tell if it is breast cancer?
Some masses can be watched over time with regular mammograms or ultrasound to see if they change, but others may need to be checked with a biopsy. The size, shape, and margins (edges) of the mass can help the radiologist decide how likely it is to be cancer.

What is DBT in mammography?
Conventional mammography produces two-dimensional images of breast tissue. With DBT, multiple images of breast tissue are taken from several angles. A computer then combines these images into several 1 mm slices through the breast that the radiologist can scroll through.
Why is it so hard to see a tumor on a mammogram?
Dense breast tissue can make it harder for doctors to detect small tumors in mammograms. Like dense breast tissue, tumors look white in mammogram images. This makes it more difficult for doctors to distinguish tumors from dense breast tissue. Because of this, for women who have dense breast tissue, mammograms may overlook tumors.
Why do radiologists do 3D breast exams?
It allows the radiologist to view the breast in thin "slices" rather than as a whole . This improves the radiologist’s ability to detect breast cancer while also reducing and the number of false alarms. The 3D imaging is performed simultaneously with a 2D mammogram, so the length of the exam does not change.

Does dense breast tissue affect mammograms?
Does having dense breast tissue affect a woman’s mammogram? Mammograms can be harder to read in women with dense breasts than in women with fatty breasts. That's because dense breast tissue and some abnormal breast changes, such as calcifications and tumors , appear as white areas in the mammogram.
Can breast cancer be detected after a mammogram?
Recent research has suggested that for women with dense breasts, a screening strategy that also takes into account a woman’s risk factors and protective factors may be the best predictor of whether a woman will develop breast cancer after a normal mammogram and before her next scheduled mammogram.
