Rosie O'Donnell's Cancer Scare

It's a cancer scare for Rosie O'Donnell, who reveals she's awaiting biopsy results after doctors found a lump in both of her breasts.

O'Donnell's mother died of breast cancer at age 39, but she remained upbeat when sharing the news on her Sirius Satellite Radio show.

"The doctors said it was very low suspicion, that they only took them out with MRI-guided needle biopsies because of my family history. But I'm okay, and I'm going to know probably on Thursday so I'll let you guys know, but I'm sure it's nothing and don't worry," she told listeners.

The 48-year-old says she had another cancer scare that proved to be benign, writing on her blog:

"I had my first lump removed at 30/thumb sized fatty tissue/I went alone/I was living in Los Angeles."

O'Donnell also said during her show, "People are very kind, but many people have been through it before."

Today, thanks to early detection, there are two and a half million breast cancer survivors in the United States.
