Litsa Menounos was diagnosed with stage 4 brain cancer in 2016. Menounos said in a YouTube video in April that both of her parents were hospitalized after testing positive for COVID-19 and that her mom's brain tumor was growing.
"My mom was healthy until August of 2016 when she was diagnosed with stage 4 brain cancer, otherwise known as glioblastoma," Menounos said.
"It's been a crazy few years for us but mom has been a total miracle," she added. "We don't listen to statistics in this house but they all said she had an average of six to twelve months [left to live]. Well, here we are almost five years later and she's had quality years."
Menounos is known for hosting Extra and E! News. She joined the WWE as an ambassador in 2013.
