Caregivers in the United States face significant economic loss and stress to care for their families and friends during and after medical treatment, a fact that highlights a "gaping hole" in the U.S. health care system, Aaron Carroll, a professor of pediatrics at Indiana University School of Medicine, writes for the New York Times' "The Upshot." Another study published in Cancer in 2009 found that two-year caregiving costs exceeded $72,000 for lung cancer, $66,000 for ovarian cancer, $59,000 for lymphoma, and $38,000 for breast cancer. The U.S. Family and Medical Leave Act grants up to 12 workweeks of leave for employees to care for a family member with a health problem, "[b]ut that leave is unpaid," Carroll writes.
