Yea it was an interesting read. Here is a key bit for anyone:

Advocates say they’d like to see more cancer screening in the province for women with dense breasts, but a Nova Scotia doctor says there isn’t enough evidence yet to support additional screening.

Breast density is a term that describes the relative amount of glandular tissue, fibrous connective tissue and fatty breast tissue as seen on a mammogram, according to the U.S. National Cancer Institute.

The institute says dense breast tissue has relatively high amounts of glandular tissue and fibrous connective tissue and relatively low amounts of fatty breast tissue.

That can make a mammogram — an X-ray used to screen for cancer — more difficult to interpret because dense breast tissue and abnormal breast changes such as tumours both show up as white areas.

Denser breasts are also a risk factor for breast cancer.

Jeannie Dale, executive director of Dense Breasts Canada, said ultrasounds and MRIs can pick up irregularities that a mammogram cannot, and should be a standard for women with dense breasts.
