Breast cancer research

Women with dense breasts do not appear to have a higher risk of dying from breast cancer, contrary to past research.

Researchers say while tumours are harder to detect in women with dense breasts, they are not more aggressive or deadly.

Dense breasts make mammograms harder to interpret because the tissue appears white, the same color as tumours.

Doctors say women with this type of breast tissue need to be aware, and regular screening may be necessary.
