Twisted Sister have canceled their plans for a 2026 50th anniversary reunion tour due to newly revealed health concerns about singer and songwriter Dee Snider.

The band posted two statements about the cancellation on their official Facebook page Thursday night. You can read them both below.

In September 2025, Twisted Sister announced their plans to return to the road for a limited number of shows, nearly 10 years after concluding their 40 and F– it farewell tour in November of 2016.

“If you’re lucky enough to be in a band that people still want to see after fifty years(!), how can you not answer the call?,” Snider declared in a press release announcing the band’s return. “In 2026, Twisted F—ing Sister will hit stages around the world because WE STILL WANNA ROCK!!”

The tour was scheduled to begin on April 25 in Sao Paulo, Brazil. But in their statement announcing the cancellation, it was revealed that Snider has been battling degenerative arthritis and undergoing multiple surgeries in recent years.

“Adding insult to injury, Dee has recently found out the level of intensity he has dedicated
to his life’s work has taken its toll on his heart as well,” the statement continues.

“He can no longer push the boundaries of rock ‘n’ roll fury like he has done for decades. … ‘I’d rather walk away than be a shadow of my former self,’ the band concludes. You can read both of the statements below.

****************************************
A lifetime of legendarily aggressive performing has taken its toll on Dee Snider’s body
and soul. Unbeknownst to the public (until now), Snider (70) suffers from degenerative arthritis and has had several surgeries over the years just to keep going, able to only perform a few songs at a time in pain.

Adding insult to injury, Dee has recently found out the level of intensity he has dedicated
to his life’s work has taken its toll on his heart as well. He can no longer push the boundaries of rock ‘n’ roll fury like he has done for decades.

Says Snider, “I don’t know of any other way to rock. The idea of slowing down is unacceptable to me. I’d rather walk away than be a shadow of my former self.”

In the immortal words of Dirty Harry, “A man’s got to know his limitations.” Sadly, Dee
Snider now knows his.
