Catherine Marshall, an associate professor at the University of Arizona, discusses how cancer affects families.

Although the dreaded "C word," cancer, no longer connotes a death sentence, the diagnosis always comes with fear and confusion. Each year 1.5 million people in the U.S. find out the bad news, and the shock reverberates within each patient's family.

Witnessing her father's battle with the disease inspired Catherine Marshall, now a research professor at both NAU and the UA, to devote her career to counseling cancer patients. She has edited a new book that serves as a guide for families navigating the cancer journey.
