During a prostate exam, Mr. Watson, age 65, learns that his prostate appears to be abnormal. The family physician conducting the exam, Dr. Kleinman, informs Mr. Watson that he may have prostate cancer. Mr. Watson agrees to a variety of tests, including blood tests, bone scans, ultrasound scanning, and a biopsy. After learning about this possible diagnosis and these tests, Mr. Watson surfs the Web for information about prostate cancer and gathers data from many different sources, including the National Cancer Society, the National Institutes of Health, Johns Hopkins University, the Mayo Clinic, and “alternative” medicine sites. He also searches for information from medical journals using MEDLINE, visits several chat rooms on prostate cancer, and joins some e-mail lists. He arrives in Dr. Kleinman's office for a follow-up appointment with a stack of material and many questions. Dr. Kleinman is surprised, irritated, and offended. He recommends that Mr. Watson have a prostatectomy followed by radiation, but Mr. Watson does not want this operation. He would rather receive a form of radiation therapy recently approved by the FDA that he learned about through his own research. Dr. Kleinman admits that he does not know much about this new treatment, but he says that he would read up on it and consult an oncologist.
