9．When it comes to medical care，many patients and doctors believe"more is better．"But what they do not realize is that overtreatment-too many scans，too many blood tests，too many procedures-may bring harm．Sometimes a test leads you down a path to more and more testing，some of which may be invasive（侵入性的），or to treatment for things that should be left alone．
Terrence Power，for example，complained that after his wife learned she had Wegener's disease，an uncommon disorder of the immune system，they found it difficult to refuse testing recommended by her doctor．The doctor insisted on office visits every three weeks，even when she was feeling well．He frequently ordered blood tests and Xrays，and repeatedly referred her to specialists for even minor complaints．Even when tests came back negative，more were ordered，and she was hospitalized as prevention when she developed a cold．She had as many as 25doctor visits during one sixmonth period．The couple was spending about $30，000a year for her care．
After several years of physical suffering and near financial ruin from the medical costs，the couple began questioning the treatment after discussing with other patients in online support groups．"It's a really hard thing to determine when they've crossed the line，"Mr．Power said．"You think she's getting the best care in the world，but after a while you start to wonder：What is the purpose？"Mr．Power then spoke with his own primary care doctor，who advised him to find a new specialist to oversee Mrs．Power's care．Under the new doctor's care，the regular testing stopped and Mrs．Power's condition stabilized．Now she sees the doctor only four or five times a year．
