It is one of the many volunteer-based patient service programs offered by the American Cancer Society. The program relies on volunteer drivers to take cancer patients to and from their treatments. Lack of transportation is often a major problem for cancer patients; many undergo daily or weekly treatment, often over a period of months, and simply have no transportation or are too ill to drive. Family and friends may help, but are not always available.
