How often does dense breast tissue turn into cancer? How do dense breasts increase breast cancer risk? Having dense breasts inherently increases the risk for breast cancer by two to four times. In a mammogram, which is a black-and-white X-ray of the breast, non-dense breast tissue appears black and transparent.
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.
Why do dense breasts increase cancer risk? There are probably several reasons that dense tissue increases breast cancer risk. One is that cancers arise microscopically in the glandular tissue. The more glandular tissue, the more susceptible tissue where cancer can develop.
What does breast cancer look like in dense breasts? Cancers typically show up as small white spots or masses on a mammogram. Dense breast tissue also appears white on a mammogram. Small areas of cancer can hide behind the dense tissue, and it’s challenging to tell the difference between normal, healthy tissue and abnormal growths.
