Willie Zinnerman of Valrico has his blood drawn by community health coordinator Helen Alvarez of St. Joseph's Hospital during the fourth annual African-American Men's Health Forum at Hillsborough Community College's Dale Mabry campus on Saturday. The forum is designed to promote awareness of prostate cancer and good health among black men. More than 500 people attended workshops on prostate cancer, diabetes and other health problems that disproportionately affect African-Americans. "People need to know," said Ricky Reynolds, 38, a former Tampa Bay Buccaneers and New England Patriots football player. "Especially young people." The American Cancer Society says prostate cancer is the No. 1 cancer to strike black men, and that African-American men have a 50 percent higher incidence of the disease than white men and are twice as likely to die from it.
