Ann Wilson, lead singer of the band Heart, has announced that she underwent an operation to remove a cancerous growth and is now undergoing preventive chemotherapy. As a result, all remaining North American tour dates for the band's 'Royal Flush Tour' have been postponed. Wilson, 74, expressed gratitude for the support and stated her intention to return to the stage in 2025, emphasizing that this health setback is just a temporary pause in her career. Preventive chemotherapy is aimed at preventing cancer recurrence after initial treatment. The band previously canceled European tour dates due to a routine medical procedure Wilson underwent, necessitating a recovery period.
