Celebrities who have battled breast cancer

11 of 15: Robin Roberts, co-anchor of the ABC show 'Good Morning America,' revealed on the program in July 2007 that she had been diagnosed with an early form of breast cancer. She said she discovered a lump in her breast during a self-examination.

Roberts underwent months of chemotherapy. She told People magazine that her 84-year-old mother and two big sisters flew to New York to be with her. Roberts placed the hand of one of her sisters, Dorothy McEwen, on her right breast to feel her lump.

'It was like marble, like a rock," McEwen told the magazine. 'I thought, 'Oh, my God.'

Roberts told People her cancer was a 'very aggressive type called triple-negative that happens in a lot of African-American women.'

Roberts' hair fell out as a result of the chemotherapy.

'Emotionally, it was devastating and draining,' Roberts said in a blog post on 'Good Morning America's website in November 2007. 'And as so many who have traveled this path before me had encouraged, as hard as it was, I knew what I had to do. I shaved it all off.'

In March 2011, Roberts told Prevention magazine that although she has been cancer-free, the disease could return and that she has been working with a nutritionist to maintain a healthier lifestyle so that it has less of a chances of doing so.

'I am convinced that the amount of red meat I consumed contributed to it,' she said. 'I would justify it, saying it wasn't like junk food. But it was also all the sodium in canned foods I ate too.'

On June 11, 2012, Roberts revealed on 'Good Morning America' that she has been diagnosed with a blood disorder called myelodysplastic syndrome (MDS) and that her breast cancer treatment had helped cause it. She went on medical leave from the show in late August 2012 and underwent chemotherapy and received a bone marrow transplant that September. Her sister Sally-Ann was her donor. Roberts returned to the series on Feb. 20, 2013.
