Cancer care has a new side effect. Along with the distress of a cancer diagnosis and the discomforts of treatment, patients now have to deal with “financial toxicity,” the expense and anxiety confronting those who face large, unpredictable costs, often compounded by decreased ability to work. The cost of health care in the United States is rising faster than the gross domestic product. The cost of cancer care is rising faster than the cost of health care, and the cost of new cancer drugs is rising faster than the cost of overall cancer care.
