Harold Lederman, the always enthusiastic and affable “Unofficial Judge” for HBO boxing, just radiates his love for all fighters and every aspect of the sport. But Lederman, 71, has learned a new meaning for radiation, the literal meaning, as he has been getting regular treatments in his fight against prostate cancer. Despite having the physically draining therapy five days a week, Lederman continues with his HBO duties in his usual fashion. Lederman, who is also a licensed pharmacist, had such treatment on Wednesday and then came with wife Eileen to Joan Guzman’s comeback fight press conference at the dazzling Washington Heights area Lucky Seven’s Tapas Bar and Restaurant. “I went for my regular checkup with my doctor on my 71st birthday,” Lederman explained. “And I took a PSA test which flagged me for the prostate cancer. I’m not complaining and I’m not trying to hide it. “I’m going to just keep fighting on, getting all my treatments. The doctor tells me my prognosis is good, that there is a high success rate.” Lederman is headed next to Cancun, Mexico, for Saturday night’s Alfredo Angulo-James Kirkland sluggers matchup and he is typically pumped up for the telecast. “That’s got to be a real war,” Lederman said. “It might be like Hearns against Hagler. I don’t think anyone thinks it will go past three rounds.” Lederman is the father of excellent fight judge Julie Lederman.
