Former Mets catcher Gary Carter, suffering from brain cancer, underwent his first radiation treatment Tuesday, according to an ESPN.com report.

“I am happy to report that it went very well,” Carter’s daughter, Kimmy Bloemers, wrote on a family website, http://sports.espn.go.com/new-york/mlb/news/story?id=6637795

Carter, 57, was diagnosed last month. His tumors are inoperable.

Bloemers wrote Carter was “pretty alert” and “feeling good with no pain.” Being treated in Florida, the Hall of Famer also began chemotherapy in pill form.

“Each day we are getting closer to a solid daily routine for dad filled with appointments, exercise, time with friends, rest, etc. so it is helpful for everyone,” Bloemers wrote.
