ARCHBISHOP Desmond Tutu will be admitted to hospital in Atlanta on Tuesday for further prostate cancer treatment. Tutu is to undergo cryosurgery, a procedure during which liquid nitrogen is used to freeze the prostate in order to destroy the cancer cells. The treatment will be carried out at the Emory University Hospital. 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. He is expected to be in hospital for one or two days.
