ARCHBISHOP Desmond Tutu was treated for prostate cancer at Emory University Hospital in Atlanta in the United States on Tuesday. The hospital’s spokeswoman Rashel Stephenson said Tutu was treated with a minimally invasive procedure called cyrosurgery which enables physicians to freeze and destroy the prostrate gland without destroying surrounding tissue. She said that Tutu was expected to be released on Wednesday morning. Prostate cancer is the second most common cause of cancer-related deaths among men, but the disease is curable if detected early enough. Tutu was was first diagnosed with prostate cancer in 1997. Extensive further testing determined that the cancer had not spread beyond the prostate, after which doctors scheduled the cryosurgery.
