NEW YORK, Dec 27: A survey of cancer doctors finds that some believe they get paid more when they administer their patients’ chemotherapy and other drugs, raising concerns about conflict of interest and the potential for overtreatment. Researchers found that oncologists, surgeons and other cancer specialists who get paid based on the number of services they provide were seven times more likely to say their pay increases when they oversee their patients’ chemotherapy treatments, compared to doctors who are paid a flat rate or salary.
