"Rollercoaster " is a comprehensive memoir-chronicle and guide to up-to-the-minute scientific research, meds and where to get help. It shows how Nancy Fox and her husband Woody Weingarten coped with breast cancer, its treatments and its aftermath - and how you can as well. Almost 250,000 new breast cancer cases are diagnosed annually. Male caregivers (husbands, boyfriends, fathers, sons and brothers) typically become a forgotten part of the equation. Yet they, too, need support. "Rollercoaster" can help provide it. Weingarten, a prize-winning journalist pro for 50 years, has led a male partners' group for two decades. Though he became an expert reluctantly, he now unflinchingly shares what he's learned.
