The American Cancer Society in Louisville says more volunteers are needed to drive cancer patients to their treatment appointments.The organization's Paige Vollmer says there were nearly 1,200 requests for transportation during a recent one-year period, but only about two-thirds of them could be filled."There are a lot of folks in the community that just don't have any other way to get to their treatment because of their diagnosis, they might just be weak or their caregiver or family member just can't take off another day of work in order to transport a patient to and from treatment," she said.Vollmer says some patients could require dozens of trips to treatment over the course of several weeks.Information about the program, called Road to Recovery, is available by contacting United Way at 2-1-1 or by clicking here.
