Low breast density worsens prognosis in breast cancer
Even though dense breast tissue is a risk factor for breast cancer, very low mammographic breast density is associated with a worse prognosis in breast cancer patients. Patient survival is affected only when low breast density is combined with an abundance of hyaluronan in the tumour, shows recent research from the University of Eastern Finland and Kuopio University Hospital. The study also found that the existing Nottingham Prognostic Index for breast cancer can be improved by including low mammographic breast density and HER2 status in the index.
