Ethan Zohn of 'Survivor' has cancer again

'Survivor' winner's cancer returns

Former "Survivor" winner Ethan Zohn's cancer has returned, The Associated Press reports. Zohn's publicist confirms doctors discovered cancer in his chest in September. News of the diagnosis was first reported by People.com. Zohn was diagnosed with Stage 2 Hodgkin's disease in 2009. Two rounds of chemotherapy didn't work, and he underwent a stem cell transplant. He was in remission until his latest diagnosis. The 37-year-old is undergoing a new form of chemotherapy called SGN-35, which involves an antibody drug that zeros in on cancer cells and is thought to be less toxic to the rest of the body.
