Dr. Susan Love’s Breast Book has long been the bible for the newly diagnosed. In this completely revised fifth edition, it also becomes a guide for those at risk of getting breast cancer, survivors interested in the consequences of their treatment, and anyone who wants to understand the new research about how the local environment influences the manifestations and treatments of many different kinds of breast cancer. Major advances being made in genetic research today mean that prevention and treatment can work not only to get rid of mutated cells (through chemo or surgery), but also to change the environment around the cells (through hormone therapy, exercise, and stress reduction). Among other promising developments discussed are advances in imaging, recognition of breast density as a risk factor, and a section focused on “personalized medicine” to help determine what kind of cancer you have and how best to treat it. Any woman facing a diagnosis, decisions about treatment, or concerns about prevention will find in Dr. Love’s book the information, guidance, and reassurance she needs.
