At the top of his daily briefing for White House reporters, Press Secretary Tony Snow said the White House's thoughts and prayers are with Elizabeth Edwards.
To Elizabeth Edwards he said, "Good going, our prayers are with you."
"As someone who has been through it, she is setting a powerful example for a lot of people," said Snow, who has survived his own battle with colon cancer. "A good and positive example."
Cancer Diagnosis Impacted Edwards Campaign
This was to be the week John Edwards unveiled what he calls a "bold" energy plan for America.
He began campaigning on the issue in Iowa on Tuesday afternoon, however by Tuesday evening, a scheduled event in Indianola, Iowa was cancelled and Edwards headed to Chapel Hill, North Carolina.
This week, the Edwards campaign issued a statement saying, "Mrs. Edwards is having a follow-up medical appointment tomorrow to a routine test she had on Monday. She's had similar follow-ups in the past and they've all resulted in a clean bill of health."
The canceled event gave birth to the rumor mill, and some were speculating that Edwards would suspend his campaign due to Mrs. Edwards's health.
In an interview with ABC News' George Stephanopoulos in May 2006, Edwards said the only thing that could stop him from running in 2008 is, "Elizabeth having her health problems come back."
However, Edwards put those rumors to rest today, saying the "campaign goes on."
Breast Cancer Survivor
In 2004, a day after he lost his bid for vice president, Americans learned that Elizabeth Edwards was battling breast cancer.
Mrs. Edwards was diagnosed with the disease and was thought to have successfully undergone chemotherapy. Doctors gave Mrs. Edwards a good prognosis and she has been regularly monitoring her health ever since.
Elizabeth Edwards proudly shaved her head before her hair could fall out. In her memoir "Saving Graces" she described her battle and the support she received from her husband.
'He Was a Great Writer'
Together, the couple had already weathered heartbreak with the death of their beloved 16-year old son, Wade, who died in a car accident in 1996.
"He was a great writer," Elizabeth Edwards said in a past interview. "He wrote one time, it was on Martin Luther King's birthday ... he said he learned you need to look at the inside of people and not the outside of people. He was seven when he said that."
