Our guest on ST Medical Monday is Mikkael Sekeres, a leading cancer specialist who writes regularly for The New York Times. He tells us about his new book, "When Blood Breaks Down: Life Lessons from Leukemia." This work carefully examines leukemia in its different forms as well as the development of drugs to treat it. As noted by Kirkus Reviews: "What makes this narrative so compelling is the author's ability to bring readers with him on his rounds as he meets each patient and family member, discusses treatment options, and follows them through weeks of treatment, reviewing lab results and bone marrow biopsies, and, when necessary, discussing next steps such as bone marrow transplants.... That [the book's] three patient narratives should prove so effective a lesson is a tribute to Sekeres as both storyteller and physician."
