Former Rolling Stones bassist Bill Wyman has been diagnosed with prostate cancer, his spokesperson has confirmed.

“He is undergoing treatment and is expected to make a full recovery as it was caught in the early stages. The Wyman family has asked for their privacy during this time,” the 79-year-old’s rep said in a statement on Tuesday.

The musician was one of the founding members of the iconic rock band along with Mick Jagger and Keith Richards in 1962. He left the group three decades later, in 1993, citing exhaustion from the band’s gruelling tour schedule. “I really don’t want to do it anymore,” Wyman said at the time.

“I have many special memories. It’s been wonderful. But I thought the last two tours with them were the best we have ever done, so I was quite happy to stop after that.”

The star was last seen in public just days ago at the wedding of Rupert Murdoch and Jerry Hall in London’s Fleet Street. He and his wife Suzanne Accosta posed for photos alongside fellow rocker Bob Geldof and his wife Jeanne Marine.

It is understood Wyman and his wife decided to announce he was suffering from cancer before fans began to notice the effect of the disease and the treatment he is receiving.
