Ann Wilson, lead singer of Heart, announced that she is undergoing preventive chemotherapy after successfully removing cancerous cells. The band has postponed remaining tour dates on the North American leg of the "Royal Flush Tour" to allow Wilson to focus on her health. She plans to be back on stage in 2025 and is grateful for her fans' support during this challenging time. The specific form of cancer was not disclosed. Preventive chemotherapy is being recommended by her doctors to prevent a recurrence. This announcement comes after a previous cancellation of the European tour due to a medical procedure. Wilson's message assures fans that this is just a temporary setback and thanks them for their understanding. Tickets will be honored for rescheduled dates once determined.
