Breast density is determined based on the number of glands and fibrous tissue in a woman’s breasts

Almost half (40%) of women in their fifties and half (50%) of women in their forties have dense breast tissue

The density of breast tissue is determined by radiologists who examine a woman’s mammogram

Dense tissues appear white on a mammogram, which may mask cancer that also shows up as white

Research has shown that a reduction of deaths from breast cancer has been correlated with early detection
