People with breasts of a higher density could be at an increased risk of developing breast cancer.
This is according to a recent research project conducted by scientists at Kaiser Permanente.
The report studied 935 women and discovered results which backed up their earlier findings.
Patients with a very early form of breast cancer who have a higher mammographic density could be at increased risk of subsequent breast cancer.
However, the later development of the cancer was more likely to be in the opposite breast.
Larual Habel, research scientist at Kaiser Permanente, commented: "While risk was elevated for both breasts, the increase was greatest and most consistent for the breast opposite to the one with the initial cancer."
She added: "While [breast density] is not a strong enough risk factor on its own, it may be possible to combine it with other factors to improve risk assessment and inform treatment decisions."
