JPMorgan's Jamie Dimon Has Throat Cancer

``Jamie Dimon, the chairman and chief executive officer of JPMorgan Chase (JPM), announced on Tuesday night that he has been diagnosed with throat cancer. "The good news is that the prognosis from my doctors is excellent, the cancer was caught quickly, and my condition is curable," the 58-year-old Dimon said in a statement. "Importantly, there is no evidence of cancer elsewhere in my body." Dimon said he would likely begin an eight-week course of radiation and chemotherapy treatments at Memorial Sloan Kettering Hospital.''
