Sheryl Crow says she is heading toward a full recovery from breast cancer surgery earlier this week.
News of Crow's cancer battle was broken Friday on her Website and confirmed by her publicist, Dave Tomberlin, who announced the 44-year-old singer-songwriter underwent 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 from Lance Armstrong.
The couple had been engaged for four months and romantically linked since 2003.
Armstrong, 34, was diagnosed with testicular cancer in 1996.
"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 Friday. "
Crow can take solace in knowing that after surgery and treatment, Armstrong was declared cancer-free and rebounded to win seven consecutive Tour de France titles.
