Breast Density May Be Related to Breast Cancer Risk


Breast density may point to breast cancer risk.

A new study presented at the annual meeting of the Radiological Society of North America points to a possible related risk between breast density and the development of breast cancer. Breast density is determined by a mammogram. The study suggests that the rate of change in this density contributes to breast cancer risk.

"Women under age 50 are most at risk from density-associated breast cancer, and breast cancer in younger women is frequently of a more aggressive type, with larger tumors and a higher risk of recurrence," Nicholas Perry, the study's senior author and director at the London Breast Institute, said in a statement.

Dr. Perry and other researchers compared breast density and cancer risk between older and younger women and reviewed the change over a period of time. The study was made up of 282 people with breast cancer and 317 control participants. In the study, the healthy participants' breast density declined with age. Breast density is often measured using a subjective method of analyzing the mammographic appearance, however, researchers used an algorithm in the study.

According to the American Cancer Society, dense breast tissue may correlate to a higher risk of developing breast cancer. So during your next scheduled mammogram, you may want to consider asking your doctor for your breast density results.
