The 74-year-old shared the news on Instagram, revealing that she recently underwent a successful operation to remove something cancerous and will now undergo preventative chemotherapy. As a result, the tour, which included over 50 shows in the US and Canada alongside bands like Def Leppard and Journey, will be rescheduled to 2025. Wilson expressed her regret to fans and promised to return to the stage in the future. With a career spanning decades and numerous hits, Heart has had a profound influence on rock music and was even honored with a lifetime achievement award in 2023. Despite this setback, Wilson remains optimistic and determined to continue making music.
