John Tesh has outlived his prognosis by nearly eight years after doctors told him in 2015 he had only 18 months to live, Page Six reports.

The former “Entertainment Tonight” co-host told reporters in a recent interview that he continues to battle a rare form of metastatic prostate cancer through an unconventional treatment approach.

“I’ve been fighting cancer successfully, still fighting it. It’s still under treatment, on and off,” Tesh said.

His medical team at MD Anderson Cancer Center in Houston uses a “pulsing” method that alternates between active treatment and allowing the cancer to grow slightly before resuming therapy, he added. Tesh is considered stable rather than in remission.

“They will let it grow for a little bit, and then get me back on treatment, back and forth,” Tesh explained. “It’s scary until you get used to it because it’s like, ‘why am I living with cancer?’”

Tesh attributed his survival to three factors: his medical team, his wife of 34 years Connie Sellecca, and his Christian faith.

“Without my wife Connie, who has been my advocate over the years, I wouldn’t be talking,” he said. “I’d be dead. I would have been dead in 2015.”

The 72-year-old said biblical passages about healing have been significant to his journey, particularly Mark 11:23, which he has tattooed on his arm.

Tesh left television hosting in 1996 to pursue music full time. He recently performed his NBA on NBC theme song “Roundball Rock” at the All-Star Game and continues hosting “Intelligence for Your Life,” a radio program broadcast on 350 stations.
