Adam Rubin of ESPN NY, An MRI exam at Duke University revealed positive news in Hall of Fame catcher Gary Carter's battle with cancerous brain tumors, daughter Kimmy Bloemers wrote in an online journal.
Carter's doctors informed the family that the tumors have shrunk 10 percent from a previous MRI exam, and approximately 75 percent since the initial detection.
"Parts of the tumors are actually dying," Bloemers wrote in the private journal, to which the family has granted access to ESPNNewYork.com.
Also, headaches recently experienced by Carter on the side of his head are the result of modest swelling -- possibly caused by radiation treatments as opposed to internal bleeding, which the family had feared, according to Bloemers.
Carter, 57, performed well on balance and memory tests at Duke. Doctors also were pleased with an examination of his vital signs.
He will need to continue to inject himself in the stomach daily until further notice to combat blood clotting.
"Physically, dad will push harder to exercise," Bloemers wrote. "It will be challenging, but dad is determined. He will also go to physical therapy three days a week and coach every day for his college baseball team."
Carter is head baseball coach at Palm Beach Atlantic University. Former major league pitcher Kent Bottenfield has been hired as associate head coach to assist in the duties.
Carter played 18 seasons in the big leagues, most notably for the New York Mets and Montreal Expos.
