Sheryl Crow recently underwent surgery for breast cancer, she revealed on her Web site Friday (February 24).

The post on SherylCrow.com said doctors expect her to make a full recovery from Wednesday's "minimally invasive" procedure, but that she will receive radiation treatment as a precaution.

Meanwhile, the singer's North American tour, slated for March and April, has been put on hold. Her Web site said Crow plans to reschedule as soon as possible.

"Approximately one in seven American women will be diagnosed with breast cancer in their lifetime, and more than 2 million American are living with breast cancer today," Crow said in the statement. "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," she continued. "I am inspired by the brave women who have faced this battle before me and grateful for the support of family and friends."

Earlier this month, Crow announced that she and fiance Lance Armstrong, a cancer survivor, had split up. The pro cyclist was diagnosed with testicular cancer in 1996 that had spread to his brain and lungs. The following year he founded the Lance Armstrong Foundation to help battle the disease. In recent years, the foundation has been raising money and awareness via the popular yellow "LiveStrong" wristbands. Crow concludes her statement by informing cancer survivors they can get assistance, education and counseling by calling the LiveStrong SurvivorCare hotline at (866) 235-7205.
