   A new study is raising questions about the reliability of breast cancer biopsies, stating 1 in 4 biopsies are incorrectly diagnosed. The Journal of the American Medical Association asked an expert panel to review 240 biopsies, labeling each biopsy sample "benign" or "malignant." In the study, pathologists missed 13 percent of the cases involving Ductal Carcinoma, 35 percent of abnormal pre-cancerous cells, and over-diagnosed 17 percent of the cases.
   Local pathologist, Dr. JJ Sreenan, says he wasn't surprised by the results of the study, stating the data is misleading. Dr. Sreenan says, the malignant and benign cases were often clear cut, but a problem arose with those cases in the middle of the spectrum. In the study, experts were only allowed to look at one biopsy sample, and could not get a second opinion from another expert. Dr. Sreenan says, at St. Rita's Medical Center, he looks at multiple samples before he makes a diagnosis. He also says, if the diagnosis isn't clear, other experts will be called in for their opinions.
   Doctor Sreenan says people shouldn't be discouraged by the study. He says, unlike the study, at St. Rita's Medical Center, he and other pathologists review biopsies thoroughly.
