‘SURVIVOR’ ETHAN ZOHN’S CANCER RETURNS

Even as he was enjoying his 20th month of remission from Hodgkin's lymphoma, Ethan Zohn worried about a relapse.

"I don't want fear or cancer to define me, but it's always in the back of your mind," the former Survivor winner tells PEOPLE in a new interview.

His fears were confirmed on Sept. 14, when doctors told him the cancer had returned in his chest.
