“In September of 2018, I was diagnosed with advanced prostate cancer, which had spread to my bones,” he told host Craig Melvin.
According to Tyler, doctors discovered his cancer during a routine physical when he was 56. He was treated with hormone therapy.
The special, which aired on HBO Max, saw the main cast — Courteney Cox, David Schwimmer, Jennifer Aniston, Lisa Kudrow, Matt LeBlanc, and Matthew Perry — revisit some of the biggest on-screen moments and discuss their memories of the show.
Asked whether the “Friends” cast already knew about his illness, Tyler said the show’s producers had been aware “for a long time” and that Schwimmer had corresponded with him on Instagram.
Tyler said his disease started “mutating” during the coronavirus pandemic, causing tumors up and down his spine. He can no longer walk.
“Of course, it’s stage 4. Late-stage cancer. So eventually, you know, it’s gonna probably get me,” he said.
Fighting back tears, he said earlier detection is key and that he regretted not listening to “my wonderful wife”.
Tyler urged viewers to “ask your doctor for a PSA (prostate-specific antigen) test” next time they go in for an examination or check-up, adding that “caught early (it is) 99% treatable.”
CNN has contacted Tyler’s representatives for further comment.
