As we reported on May 21st, Gary Carter was found to have four tumors in his brain. We held off speculating and reporting until further information was available.
It was revealed that the the tumors in Carter's brain are believed to be malignant, but 100% confirmation won't be available for another week or so.
The tumors are inoperable since "it is like a snake of tumors that are connected across the back of the brain" (quoted from Carter's daughter Kimmy).
ESPN has been given the privilege of covering Carter's journey with access to daily journals. Some of the excerpts of interest are from his daughter Kimmy:
Although the tumors are inoperable, Dr. Friedman of Duke University Medical Center plans not to prolong Carter's life, but to cure him of the Grade 4 Glioblastoma.
The Carter family is appreciative of the love and support from such notable stars as: Duke Head Coach Mike Krzyzewski and former players Bert Blyleven, Jerry Royster, Howard Johnson, Hank Bower, Phil Niekro, Buddy Bell, and Tommy Hutton.
The Carter family is also appreciative of the support, prayers and well wishes of fans; the one's who cheered for him as a ballplayer, and those who pray for him to win the biggest game...life.
