I strongly recommend it for specialists and non-specialists, professionals and non-professionals, and for both women and the men who care for them." Dimitrios Trichopoulos, MD, Vincent L. Gregory Professor of Cancer Prevention and Professor of Epidemiology Harvard School of Public Health, Boston, MA USA. Breast cancer is the most common and feared of all cancers affecting women in the developed world.
