 The lead singer of the rock band Heart says she has cancer. Ann Wilson says she had surgery to remove a cancerous growth and is recovering steadily. But she says her doctors urged her to undergo preventive chemotherapy and take time off from performing in order to fully recover. That means the rest of the shows on Heart's North American tour will be postponed to dates in 2025. Over 50 shows at stadiums and arenas in dozens of cities across the U.S. and Canada are impacted. Best of luck to her.
