Sheryl Crow undergoes surgery for cancer

St Etienne (France): Grammy winner Sheryl Crow had surgery for breast cancer and postponed a North American tour scheduled to start next month, the singer announced on her website on Friday.

Crow's website said she underwent a successful surgery on Wednesday and described the procedure as "minimally invasive."

Doctors said her prognosis was excellent and she would have radiation treatments as a precaution.

"I am joining the more than 2,00,000 women who will be diagnosed with breast cancer this year," Crow said.

"We are a testament to the importance of early detection and new treatments. I am inspired by the brave women who have faced this battle before me and grateful for the support of my family and friends," Crow added.

Last month, Crow, 44, and Lance Armstrong, seven-time winner of the Tour de France cycling race and a survivor of testicular, brain and lung cancer, announced they were scrapping plans to get married after a two-year relationship.

Crow is calling off her March-April tour but intends to reschedule her tour.

The Missouri native was a school teacher before starting a singing career that led to a job as a backup singer to Michael Jackson and later to nine Grammy Awards.

Her hits include All I Wanna Do, Everyday is a Winding Road, If it Makes You Happy and Soak Up the Sun.
