Singer Sheryl Crow has had to postpone her US tour after undergoing surgery for breast cancer.
Following the "minimally invasive" operation at a Los Angeles hospital on Wednesday, Crow will now have radiation therapy.
But doctors are confident they have caught the disease early enough and the 44-year-old will make a full recovery.
Crow's publicist says in a statement on her website,
"Sheryl Crow underwent successful minimally invasive surgery for breast cancer. Her doctors confirm her prognosis as excellent and she will receive radiation treatment as a precaution." 
Her publicist adds,
"With much regret, she must postpone her complete tour of North America which was scheduled for March/April. It is Sheryl's intention to reschedule as much of the tour as reasonably possible."
