A tumor on former Mets Hall of Fame catcher Gary Carter's brain "appears to be malignant," according to doctors at Duke University. "Following a thorough examination and assessment of Gary Carter, biopsies were performed (Friday) morning from a tumor located in Mr. Carter's brain," Dr. Allan H. Friedman and Dr. Henry S. Friedman, co-deputy directors of The Preston Robert Tisch Brian Tumor Center at Duke, said in a statement. "The preliminary results are that his tumor appears to be malignant. Once the pathology report is available, which will take several days, we will discuss treatment options with Mr. Carter and his family. "In the meantime, Mr. Carter is in excellent spirits and good physical condition. He is resting comfortably, surrounded by his family. We hope that his friends and fans will continue to pray for Mr. Carter and his family during this time." Carter, 57, who just completed his second season as Palm Beach Atlantic University's baseball coach, announced last Saturday that an MRI had revealed four small tumors on his brain.
