HEART has postponed its “Royal Flush” tour so that singer Ann Wilson can undergo cancer treatment.

The 74-year-old musician said in a statement Tuesday (July 2) that she recently underwent an operation to remove “something that, as it turns out, was cancerous.”

“The operation was successful & I’m feeling great but my doctors are now advising me to undergo a course of preventative chemotherapy & I’ve decided to do it,” she added. “And so my doctors are instructing me to take the rest of the year away from the stage in order to fully recover.”

Wilson said she “absolutely” plans to return to the stage in 2025 and will share details with fans “as soon as we can.”

“Thank you for all the support. This is merely a pause. I’ve much more to sing,” Ann concluded.

HEART announced on social media that it was postponing the remainder of the tour “due to medical reasons.” The band said tickets will be honored for the rescheduled dates, with more information to be announced in the coming weeks.
