It seems Elizabeth Edwards has a good amount of energy, despite her diagnosis of incurable cancer in March, following a previous battle with breast cancer. Perhaps her energy stems from the fact that she is asymptomatic and feeling quite well.

About her health and her husband's campaign, Edwards says, "I feel good and honestly, the campaign is more helpful. I don't sit at home and worry about what's going to happen to me a year from now, two years from now, 10 years from now. I take a pill in the morning and that's when I think about cancer. No other time of the day do I think about my cancer."

While she does admit she doesn't want to push herself too hard, she doesn't worry about the accompanying her husband, Democratic presidential candidate John Edwards, on his busy campaign trail. And she doesn't worry about what others might think of her decision to press forward.

It was all about the bike for Democratic presidential candidate John Edwards this past Wednesday. Decked out in spandex bike shorts, he pedaled with champion cyclist and cancer survivor Lance Armstrong on the Register's Annual Great Bike Race Across Iowa (RAGBRAI). Riding at an easy pace of 10 to 12 mph from Hampton to Cedar Falls, Edwards chatted with riders about their pressing issues, including their concern for his wife Elizabeth who was diagnosed with a recurrence of breast cancer this year.

About his bike trek, Edwards commented, "This is an accident waiting to happen."

Why did he take on the challenge? "Lance has become a friend," Edwards said. " Proud of what he's doing, particularly on the cancer issue. It's obviously very important to us personally. And I've heard about this race -- err, race -- this ride, ever since I'd been coming to Iowa so I wanted to see what it looked like."

California Democratic Rep. Juanita Millender-McDonald, subject of an April 20 post, died of cancer early Sunday. She was 68.

"Juanita Millender-McDonald was a trailblazer, always advocating for the full participation of all Americans in the success and prosperity of our country," said House Speaker Nancy Pelosi. "The dignity with which she faced her illness was an indication of the determination with which she always served the people of her district."

Millender-McDonald, a native of Birmingham, Alabama who served a district including Compton, Long Beach, and parts of Los Angeles, is the second member of Congress to die this year of cancer. Republican Rep. Charles Norwood Jr. of Georgia died in February after his battle with both cancer and lung disease.

Governor Arnold Schwarzenegger has 14 days to set a date for a special election to fill Millender-McDonald's seat.

The congresswoman is survived by her husband, James McDonald, Jr., and five adult children.

Elizabeth Edwards, wife of Democratic presidential candidate John Edwards, has had many routine medical follow-ups since her 2004 breast cancer diagnosis. And all of them -- until just a few days ago -- resulted in what is generally termed a clean bill of health.

The term doesn't always come with a sense of relief for those of us surviving breast cancer -- or any cancer for that matter -- because it only really defines what our bodies are telling us at one specific moment. There are no magic blood tests, no special body scans, no conclusive ways of determining whether or not cancerous cells have gone astray and will one day surface again.

I asked my oncologist after my first six-month follow-up how he would know if my cancer returns. He told me it's really up to me to determine whether it comes back. It's up to me to get mammograms and ultrasounds and MRIs. It's up to me to report any symptoms and suspicions. It's up to me to track my general well-being so that it will be clear when something feels not-so-right. If I have a persistent cough or headaches that won't subside, my doctor will take action with X-rays and scans and tests. But as long as I feel fine and nothing troubling presents itself, then I remain in the clean-bill-of-health club.

Edwards no longer has a clean bill of health. But she is determined to use her newest diagnosis -- stage four metastatic cancer of the bones, considered treatable but not curable -- to work toward the best health she can acquire for as long as she can hold onto it. And that is about as good as any of us can do.
