One in eight women in the U.S. will be diagnosed with breast cancer in her lifetime. This essential guide introduces core concepts about breast cancer, and debates subtopics through essays that present more than one viewpoint. Across four chapters, this book analyzes whether annual mammograms save lives, whether preventive mastectomies save lives, whether abortion increases the risk of breast cancer, and whether breast cancer awareness has become commercialized and exploitive. Essay sources include Karuna Jaggar, Shalmali Pal, Lisa Newman, Colleen Joy McCullough, and the Dana-Farber Cancer Institute.
