Breast density information to be included with all N.S. mammogram results

Women with higher breast density have an increased risk of cancer

It's a frightening statistic that far too many women in Nova Scotia are aware of: One in eight will be diagnosed with breast cancer in their lifetime.

But now the Nova Scotia health care system is aiming to give women new and potentially life-saving information on their breast health with every mammogram report.

Women in the province will now be able to learn whether they have dense breasts with the results of their mammogram as part of the Nova Scotia Breast Screening Program.


Breast density can affect a patient's risk of cancer and how easily their cancer can be detected. 

"We have been very aware of breast density for many years as radiologists and we've recognized its importance," said Dr. Sian Iles, a radiologist who is also the medical adviser for the Nova Scotia Breast Screening Program.

"That's part of the reason why we started this research into breast density here, which led to the development of this software program."

The software used to measure breast density was developed by Densitas Inc. of Halifax.

The Nova Scotia Breast Screening Program at the IWK Health Centre helped oversee the development of the new process and its rollout to various regional facilities.

"It's my understanding that we are the first province to have a standardized approach and system that is able to do it province-wide," said Nova Scotia Health Minister Randy Delorey. 


"That's what makes us, and this program, unique."

"We encourage women to talk to their health-care providers about whether screening is right for them and breast density information will help support that conversation," said Dr. Iles.

About 65,000 screening mammograms were performed in Nova Scotia in 2018.

Mammograms remain the international standard method of screening for early detection of breast cancer.
