Ann Wilson has revealed that she's finished with chemotherapy and ready to prepare for Heart's rescheduled 2025 tour. The rockers were set to play additional North American dates this summer and fall but had to postpone the trek so Wilson could undergo treatment. "I underwent an operation to remove something that, as it turns out, was cancerous," Wilson announced in July. "The operation was successful and I'm feeling great but my doctors are now advising me to undergo a course of preventive chemotherapy and 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."
