"Bill Wyman, former member of the Rolling Stones, has been diagnosed with prostate cancer. He is undergoing treatment and is expected to make a full recovery as it was caught in the early stages," the Rolling Stones' rep said in a statement. "The Wyman family has asked for their privacy during this time. No further comment will be made at this point."
After joining the group in 1962, Wyman served as the Rolling Stones' bassist until his 1993 departure from the band following their Steel Wheels tour. In November 2012, Wyman briefly reunited with his former band mates at the Stones' London concert, performing "It's Only Rock 'n Roll" and "Honky Tonk Women" with the group. Wyman was inducted into the Rock and Roll Hall of Fame with the group in 1989.
Since his exit from the Stones, Wyman has fronted his own group the Rhythm Kings. The 79-year-old Wyman's latest solo LP Back to Basics was released in June 2015. He's also penned two books about his time with the Stones: 1997's Stand Alone and 2002's Rolling With the Stones.
On Saturday, Wyman attended the London wedding of Rupert Murdoch and Jerry Hall, Mick Jagger's ex-wife. According to the Guardian, Wyman showed no signs of illness and mingled with guests.
The Rolling Stones are currently on tour in South America. They recently announced they would perform a free concert in Cuba on March 25th, marking the first time a British rock group has performed on the island since their 1959 revolution.
