Singer Sheryl Crow has postponed her US tour after undergoing surgery for breast cancer.

Following the "minimally invasive" operation at a Los Angeles hospital on Wednesday (22FEB06), 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."

Crow adds in her own words, "Approximately 1 in 7 American women will be diagnosed with breast cancer in their lifetime and more than 2 million American are living with breast cancer today. I am joining the more than 200,000 women who will be diagnosed with breast cancer this year.

"We are a testament to the importance of early detection and new treatments. I encourage all women everywhere to advocate for themselves and for their future - see your doctor and be proactive about your health.

"More than 10 million Americans are living with cancer, and they demonstrate the ever-increasing possibility of living beyond cancer. I am inspired by the brave women who have faced this battle before me and grateful for the support of family and friends."

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."
