Despite cancer costing Americans a staggering $87.8 billion in 2014, just about 5 percent of that tab, or $4.4 billion, came out of patients pocketbooks, according to government figures. Though insurance coverages can vary widely from case to case, the most common types of coverage – employer-based, Medicare and individual market plans – remain critical for cancer patients, according to a new report from the American Cancer Society Cancer Action Network (ACS CAN), the advocacy affiliate of the nation's largest non-government, not-profit funding source of cancer research.
