Ann Wilson, the lead singer of rock band Heart, has announced that she has been diagnosed with cancer.

The 74-year-old wrote in an Instagram post: “I recently underwent an operation to remove something that, as it turns out, was cancerous. The operation was successful & I’m feeling great but my doctors are now advising me to undergo a course of preventive chemotherapy & 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.”

Heart have therefore cancelled their next tour, entitled Royal Flush, which was due to have visited 48 cities across the US and Canada during the autumn. In May, Heart cancelled their UK and Europe summer tour, which included six UK arena dates, citing Wilson’s operation.

In her Instagram post, Wilson added that she intended to be back on stage in 2025, writing: “This is merely a pause. I’ve much more to sing.”
