RALEIGH, N.C. — Elizabeth Edwards underwent more tests Friday to determine how far her breast cancer has advanced. One breast cancer survivor said when a well-known person like Edwards goes public with her diagnosis, it can serve as a wake-up call for women everywhere.

Sandy Ogburn, a breast cancer survivor herself, said all of the races and all of the campaigns geared toward breast cancer awareness are, no doubt, helpful, but when a public figure like Edwards is diagnosed with the disease, it can really strike a chord with thousands.

"She's been living this active and vital life and all of the sudden, she gets this news. It reminds women, 'I do need to get a mammogram,'" she said.

Ogburn understands the strain Edwards may be under. When she was diagnosed 13 years ago, she was a City Council member. She said there is a pressure to keep up a public face.

"You learn a lot. It's a humbling experience because you learn you're not in control of as much as you thought you were in control (of)," she said.

Ogburn also said the outpouring of support taught her how good people are. Edwards is also learning that as well, as her husband's office is being flooded with calls of well-wishes and encouragement.

Edwards' friends said she is a practical, problem-solving person and she will do great.
