Sheryl Crow to Fully Recover from Breast Cancer Surgery

Sheryl Crow says she is heading toward a full recovery from breast cancer surgery last week. News of Crow's cancer battle was broken on Friday on her website and confirmed by her publicist, Dave Tomberlin, who announced the 44-year-old singer suffered a successful surgery on Wednesday.

"Her doctors think her prognosis is excellent," Tomberlin said. The nine-time Grammy winner, who described the procedure as "minimally invasive," will now begin precautionary radiation treatment, according to a statement on sherylcrow.com.

"I am joining the more than 200,000 women who will be diagnosed with breast cancer this year," Crow says on the site, adding the cancer was detected early. "I am inspired by the brave women who have faced this battle before me and grateful for the support of family and friends."

To allow time for rest and recuperation, Crow has scrapped her North American tour, which was scheduled to kick off next month and run through April in support of her recent album, the Grammy-nominated "Wildflower". Crow says she hopes to make up the dates as soon as possible.

Everyday in February must seem like a winding road to Crow. The cancer announcement comes exactly three weeks after she made public her split with Lance Armstrong. The 34-year-old Armstrong was also diagnosed with cancer in 1996 - testicular cancer. "Once again I'm reminded of just how pervasive this illness is, as it has now touched someone I love deeply," he said in a statement on Friday.
