The Rolling Stones' 63-year-old drummer Charlie Watts is suffering from throat cancer but should recover after radiotherapy, a band spokesman said on Saturday.
Watts was diagnosed in June after a minor operation and is now reaching the end of his treatment at a London hospital, the spokesman said in a statement to British media.
"He's expected to make a full recovery and start work with the rest of the band later in the year," he added.
Watts, who has a reputation as the quietest member of the legendary British band, gave up smoking decades ago.
"He's very positive because he's been told he has every chance of being completely cured," a family friend was quoted as saying in The Mail on Sunday newspaper.
"The last thing he wants is everyone calling and making a fuss, thinking he's going to die."
The spokesman said Watt's treatment had not interfered with any of the Stones' tour or recording plans. The rest of the group were "relaxing between work commitments," he said.
