Query: "A must read for any woman"

I recently completed Deborah A. Cohen's book about breast cancer, and I was blown away. Ms. Cohen has made a very important contribution to the woman's health field while fighting her own battle with breast cancer. I thought the tone of the book was non-threatening and engaging, and the content helpful, interesting, and enpowering. I'd highly recommend this book to anyone who has breast cancer, has a family member or friend with breast cancer, or simply wants to better understand the breast cancer experience.
