Florence Williams

Science writer Florence Williams experienced what felt like a brain injury when her husband left her after more than 25 years together. So she decided to explore the connection between heartache and physical pain — including possible changes in the immune, digestive and nervous systems. Her new book is Heartbreak: A Personal and Scientific Journey.

In her new book, Breasts: A Natural and Unnatural History, Florence Williams offers her take on why breasts are getting bigger and developing earlier, why tumors seem to gravitate toward the breast, and how toxins from the environment may be affecting hormones and breast development.
