WASHINGTON (CNN) -- Singer Sheryl Crow appeared on Capitol Hill Wednesday to support Senate Majority Leader Harry Reid's legislation that provides funding for research seeking the connection between breast cancer and the environment.

"What we're asking for is more money," Crow said at a press conference. "The war on cancer needs to really -- it needs to be won." (Watch video: Crow on the Hill)

The legislation has been pending for over eight years.

Crow was diagnosed with breast cancer a little more than a year ago but calls herself cancer free after a lumpectomy and radiation treatment.

Crow told CNN's Soledad O'Brien Wednesday on America Morning that she "was one of those people that that really felt, look, I'm healthy, I'm on the go, I treat myself pretty healthy and, yet, here I have breast cancer."

Crow's appearance on Capitol Hill comes less than a week after Elizabeth Edwards, wife of Democratic presidential candidate John Edwards, announced that her breast cancer had returned.
