In a study with 504 women, researchers at the University of Liverpool led by Dr. Diane Scutt found that a difference in breast size was linked to an increased risk of cancer in a fairly linear way, with every 100 milliliters of difference equating to an increase in the risk of cancer of 50 percent. The average breast size is approximately 500 milliliters, so we’re talking fairly sizable differences here.
