Young women face a lot of pressure as they begin their careers, find a mate and consider starting a family. And when those same women face serious illnesses, there’s extra pressure to pretend all is well.

Her new book is called “Invisible: How Young Women with Serious Health Issues Navigate Work, Relationships, and the Pressure to Seem Just Fine” (Beacon Press).
