For as long as medicine has been a practice, woman's bodies have been treated like objects to be practiced on: examined and ignored, idealized and sexualized, shamed, subjugated, mutilated, and dismissed. The history of women's healthcare is a story in which women themselves have too often been voiceless-a narrative written from the perspective of men who styled themselves as authorities on the female of the species, uninformed by women's own voices, thoughts, fears, pain, and experiences. This continuing cultural and societal legacy results in the (mis)treatment and care of women. While the modern age has seen significant advancements in the medical field, the notion that female bodies are flawed inversions of the male ideal lingers on-as do the pervasive societal stigmas and ignorance that shape women's health and relationships with their own bodies. Memorial Sloan Kettering oncologist and medical historian Dr. Elizabeth Comen draws back the curtain on the collective medical history of women to reintroduce us to our whole bodies-how they work, the actual doctors and patients whose perspectives and experiences laid the foundation for today's medical thought, and the many oversights that remain unaddressed. With a physician's knowledge and empathy, Dr. Comen follows the road map of the eleven organ systems to share unique and untold stories, drawing upon medical texts and journals, interviews with expert physicians, as well as her own observations from treating thousands of women. Empowering women to better understand themselves and advocate for care that prioritizes healthy and joyful lives-for us and generations to come-'All In Her Head' is written with humor, wisdom, and deep scientific and cultural insight. Eye-opening, sometimes enraging, yet always captivating, this shared memoir of women's medical history is an essential contribution to a holistic understanding and a much-needed reclaiming of women's history and bodies.
