On a hot summer day in 2006, an African-American woman walked into the emergency room at Grady Memorial Hospital in Atlanta complaining of a large sore on her breast. Her family had urged her to go to the hospital, she said, because the stench from the infected wound had become intolerable. Doctors discovered a cancerous tumor so large it had burst through her skin.

When Otis Brawley, then medical director of the hospital's cancer center, asked the woman when she had first noticed a lump in her breast, she recalled that her son had been in second grade. He was now a high school junior. Even after the tumor first broke through her skin, she admitted waiting nearly two more years to seek treatment. She had no health insurance, she explained. Apparently she hadn't realized that, as a public hospital, Grady accepts and treats the uninsured. Despite the intense treatment that followed—a mastectomy, along with radiation and chemotherapy—her cancer was already so advanced that she was dead within a year.

Her case might seem extreme, but Brawley says at Grady's cancer center, where the majority of patients are minorities and many are uninsured, "that sort of thing happens several times a year." When he examined hospital records, he found that, on average, about 40 percent of the breast cancer patients treated there have already reached stage IV, for which the five-year survival rate is just 20 percent (versus nearly 100 percent for those diagnosed at stage 1). By comparison, only a small percentage of the patients he saw at Emory University's cancer institute, which serves a largely white, middle-class population, had progressed to a late stage when they were diagnosed.
