Reality TV Tragedies: The Saddest and Most Shocking Deaths
Jennifer Lyon, Survivor Palau
After finishing fourth in Survivor's 10th season, a then-33-year-old Lyon was diagnosed with stage three breast cancer in 2005. She underwent a double mastectomy and chemotherapy, but the cancer later metastasized, and she passed away at the age of 37 on Jan. 19, 2010. "Jenn did such a good job of showing me how to love someone who is dying," Survivor host Jeff Probst told Us of the reality contestant.
