Celebrities who have battled breast cancer

4 of 15: Rock musician Sheryl Crow was diagnosed with stage one breast cancer in February 2006, weeks after she and Tour de France champion Lance Armstrong announced they were ending their engagement. The singer, who was 44 at the time, said on CNN show 'Larry King Live' in August of that year that she was cancer-free.

'Obviously, there's always that fear that there's going to be one radical cell out there floating around,' she said. 'But I feel great. I went through seven weeks of radiation. And I feel - I feel back to normal. In fact, I probably feel better than I did before.'

Crow said she underwent a lumpectomy had a needle biopsy performed on her other breast, adding: 'I had ductal carcinoma in situ in the left breast and the right, just, atypia which are cells that you want to keep an eye on.'

In 2011, Crow revealed that her cancer experience prompted her to changed her diet to include seasonal, organic, sustainable foods, and 'cancer-fighting spices.' She released a cookbook, 'If It Makes You healthy,' which was co-authored with chef Chuck White.
