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."

Fred Thompson, actor and former United States Senator from Tennessee, made the announcement today that he was diagnosed with lymphoma a few years ago and now is in remission.

Thompson added to that announcement that he was considering running in the 2008 Presidential Election. He stated today on Fox News, "I have had no illness from it, or even any symptoms. I am in remission, and it is very treatable with drugs if treatment is needed in the future -- and with no debilitating side effects".

You can find Thompson playing a district attorney Arthur Branch on the NBC drama Law and Order.

Presidential candidate John Edwards and his wife Elizabeth will appear tonight on 60 Minutes where they will publicly discuss with Katie Couric Elizabeth's newest cancer diagnosis and their decision to continue on in the presidential race.

Elizabeth, 57 and first diagnosed with breast cancer in November 2004, shared Thursday that her cancer has returned, this time in her bones. Considered stage four and treatable -- but not curable -- her cancer has generated much discussion and awareness about the workings of this life-threatening disease.

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.

Lance Armstrong means business. He says his new race is finding a cure for a disease that kills 600,000 people a year. Lance is a ten year testicular cancer survivor and was diagnosed at the age of 25.

Yesterday, Lance urged Iowans to support a presidential candidate who's dedicated to expanding cancer research. In a speech to 1,500 guests of the Greater Des Moines Partnership's annual dinner, the seven time Tour de France Champion described the power Iowa holds as the nation's lead-off state in the presidential nominating process.

"The cancer question has to be asked, and it has to be on the agenda for the most powerful man in the world", Armstrong said.

Go Lance!

Just before my treatment for breast cancer began and during a consultation about what chemotherapy drugs I was about to receive, my oncologist stepped away from my exam room to check on something. When she returned to the room, she told me that she was determining whether or not I qualified for a clinical trial. I had no idea what this meant at the time. All I knew was what she told me -- that my prognosis was too good at that moment to qualify for anything currently under study. I did not fit a profile for anything. I was not a candidate for a clinical trial.

I now know that clinical trials are a critical component of research -- they validate a drug's success or weakness and they provide hope for many who may be at the end of their treatment rope and need something new to consider. A clinical trial is a comparison of standard treatments to newer treatments in an effort to discover better methods for the diagnosis and treatment of cancer. Doctors, scientists, and other health professionals conduct these tests according to strict guidelines set by the Food and Drug Administration -- which establishes mandatory guidelines to ensure the maximum safety of the patient.

Clinical trials rely on volunteers -- and sadly, there is a current shortage of patients willing to participate in trials. Experts say that, for the past few decades, just five to 10 percent of all cancer patients in the United States have joined a clinical trial. There is an urgent need -- because the demand for willing, eligible participants far exceeds the supply. Some experts are even recommending that the small pool of candidates that does exist be rationed to only the most important cancer studies -- leaving other studies with no hope for completion. There is no good solution in sight. But the reasons for the shortage are becoming apparent. It's not that patients are unwilling to join. It's that they are unaware, uninformed, not even sure this opportunity is possible -- because doctors are not suggesting trials to their patients. Treatment on a protocol is more demanding for doctors than routine medical care. And it costs doctors to submit to a trial. And trials burden doctors with regulations and paperwork. And some doctors worry about litigation if something experimental goes wrong. So they often don't approach the topic -- and the result is that a wonder drug may sit in a dark freezer because there are not enough people to test it. This potential wonder drug may never show promise, may never save a life, may never see the light of day.

So I guess my oncologist was ahead of the game in this matter -- she compared my diagnosis and prognosis with the needs of all available clinical trials and found that there was not match. Had she not done this, I would have never thought to ask about the possibility -- which is exactly what patients should do instead of waiting for a doctor to make the suggestion. Because it may never happen.

I clearly remember reading a pamphlet about a test that might determine with pretty good accuracy whether or not I would benefit from chemotherapy for breast cancer. This was more than a year ago and I hoped, prayed, wished upon a star that I would be a candidate for this test -- and that the result would reveal that I did not need the toxic chemotherapy that I feared with every fiber of my being. But I did not qualify for this test because it's only effective for tumors that are estrogen receptor positive -- and I am negative. So I received chemotherapy and while I've survived it, there still remains an important issue -- did I need it?
