Book on Tucson doctor’s mission to make cancer more treatable

Dr. Tom Grogan, a professor emeritus at the University of Arizona College of Medicine, invented a cancer diagnosis instrument that is used for 20 million patients per year worldwide. Dr. Grogan’s instrument allows experts to identify the cellular characteristics of a patient’s disease so treatment can be personalized and reach every last cancer cell. Dr. Grogan’s book “Chasing the Invisible: A Doctor’s Quest to Abolish the Last Unseen Cancer Cell,” tells the story of the hurdles he faced in developing the instrument, including investors’ lack of interest, millions in debt and protests from the medical community. We’ll hear more from Dr. Grogan.
