Heart announced on Tuesday (July 2) that the group is postponing the remainder of its North American tour dates headlining Royal Flush Tour and Journey/Def Leppard Stadium tour, due to frontwoman Ann Wilson’s recent health issues.

“I underwent an operation to remove something that, as it turns out, was cancerous,” Wilson shared in a press statement. “The operation was successful & I’m feeling great but my doctors are now advising me to undergo a course of preventive chemotherapy & I’ve decided to do it. And so my doctors are instructing me to take the rest of the year away from the stage in order to fully recover. To the ticket buyers, I really do wish we could do these gigs. Please know that I absolutely plan to be back on stage in 2025. My team is getting those details sorted & we’ll let you know the plan as soon as we can.”

Wilson concluded by noting, “This is merely a pause. I’ve much more to sing.”

Fans are encouraged to hold on to their tickets for the upcoming postponed dates. In May, Heart canceled their European tour dates.

Started by sisters Ann and Nancy Wilson in 1974, Heart’s Royal Flush tour marks the band’s return to the road for the first time in five years. The North America leg kicked off April 20 in Greenville, South Carolina, with Cheap Trick as support on most dates, while Squeeze was set to open on a handful of those now-canceled summer European dates.

Recognized as the first female-fronted hard rock band, Heart took their place among the greats when they were inducted into the Rock And Roll Hall of Fame in 2013.
