Heart postpones tour as Ann Wilson shares health issues

July 2 (UPI) -- Heart is postponing its tour amid news lead singer Ann Wilson will undergo cancer treatment.

Wilson, 74, said in a statement Tuesday 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," the singer said. "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," the star added.
