There are 100 lymph nodes in the neck region. That's what my radiation oncologist told me during my recent follow-up exam. At any given time, one or more of these nodes may be palpable. This isn't always bad news. A cold, allergies, even dental work can cause them to react. This is good news for me.

When I saw my medical oncologist eight weeks ago, he felt a swollen lymph node on the right side of my neck. He wasn't worried about it. I was. So we talked, and I learned that changes in lymph nodes are normal. He would know -- one of his primary diseases of study is lymphoma -- so I set my fears aside.

My enlarged lymph node slowly disappeared. At times, though, I'll feel it resurface. It's small when it presents itself, but it's still there. My radiation oncologist agreed: it's there. But it's elongated. It's not swollen in a round, tight, puffy way. These are the nodes that signal cancer.

I'm never quite sure what to do about vitamin supplements. Should I take them? Or should I leave them?

Sometimes I think supplements could surely help me with whatever I'm lacking in my diet. Other times I don't want to mess with what might be working just fine in my body. Now if a doctor tells me my iron is low, I'll take a supplement to boost my levels. But if there is nothing apparently off kilter in my system, I tend to just leave things alone.

I'm glad at the moment for my current plan. Because nutritionists now suspect that high doses of vitamins and minerals -- believed by some to prevent cancer -- might actually be harmful.

Think about this:

The American Medical Association journal JAMA recently reported that high doses of antioxidant supplements can be harmful. Vitamin advocates challenged the analysis, saying it excluded large studies from China and Italy showing antioxidant supplements lowered mortality risk.

Consumers still should read labels carefully.

"Some of the things called daily vitamins can be higher than what we think is desirable," says one researcher who urges consumers to look for something about 100 percent of the daily value. That's really all people need, she declares. But a healthy diet is still most important and can prevent the need for supplements altogether. Yet for those who are sick, don't have access to nutritious food or for some other reason cannot eat well, the 100-percent rule is a good guide.

Aspirin and painkillers such as ibuprofen have been deemed too risky for use in the prevention of colon cancer, according to a federal task force.

The risk of intestinal bleeding, stroke, kidney failure, and other health problems led the US Preventative Services Task Force to conclude that taking more than 300 milligrams per day of drugs like Motrin, Advil, and Aleve is just too risky to outweigh the potential benefits of preventing cancer. And while taking less than 100 milligrams of such drugs can reduce the risk of heart disease, it does nothing to lower the rate of colon cancer.

Details about this task force study are published in Monday's issue of the Annals of Internal Medicine.

It is no secret that our culture has a fascination with celebrities. In attempting to figure out exactly why, I have come to the conclusion it might be no more of a mystery other than they are people we all know in common. As human beings, we are naturally intrigued by other human beings. But if I try to talk to you about my neighbor, and you do not live in my neighborhood, you will have no idea who I am talking about or how to relate information I am sharing about that person because you have no point of reference. However, celebrities are people we all know of -- they become familiar in that we hear about them every day -- we see images of them every day in the news.

Before being diagnosed with breast cancer, a woman might not have paid much attention to breast cancer. Oh yes, the breast cancer awareness campaigns are raising awareness, but we do not really like to spent too much time dwelling on potentially life-threatening events unless we are compelled to do so -- usually with a breast cancer diagnosis.

Over at Silicon Valley Moms Blog, Tekla blogged the top ten things this group of moms have learned since they began blogging seven months ago in Moms boobs and other lessons learned. Interestingly, and unfortunately accurate, number six on the list is:

"6. If you talk about breast cancer, your blog stats go way down for days and days. Everyone knows it's something women need to deal with, but clearly no one wants to read about it."

And so, if you are newly-diagnosed with breast cancer, or know someone who is, and haven't spent much time focused on breast cancer before diagnosis, there are many women we all know in common who have been diagnosed with breast cancer and many of them as breast cancer survivors. In time, you will personally meet other breast cancer survivors and realize you are not alone and be inspired by their hope, strength, courage and companionship. Until then, you can read an extensive list of 100 famous women who have faced breast cancer down and gone on -- here.

Someone raced for the cure -- in celebration of me. I am honored and flattered and so thrilled to have received in the mail today a t-shirt and the crumpled piece of pink paper than hung from my aunt's back -- with my name on it -- as she ran this 5K race in Aspen, Colorado on July 15. It was the 16th annual Susan G. Komen Race for the Cure in Aspen, and my aunt has run for me for two years now. I have a t-shirt and pink piece of paper from last year too. Maybe one day I will run it for myself. First, I have to master the whole running thing.

The Susan G. Komen Breast Cancer Foundation Race for the Cure began in 1983 with 800 participants. Today the Komen Race for the Cure is the largest 5K event in the world. And in 2005, more than one million people participated in more than 100 races designed not only to raise funds but to also educate the public about early detection -- about how it is the most effective method of surviving this life-threatening disease. The five-year survival rate is 95 percent when the disease is discovered while still confined to the breast. I'm proud to have found my own lump early, before it had spread outside my breast. And I am proud to have been a part of a race -- even in name only -- that might make this early discovery possible for many more women to come.

There is no doubt that the new cervical cancer vaccine -- Gardasil -- is revolutionary. But writer Peter Sprigg, vice president for policy at the Family Research Council, shared yesterday on the washingtonpost.com that the public should consider two cautions when digesting the news of this breakthrough medical advance. He urges us, first, to understand that the vaccine is not 100 percent effective. It is 100 percent effective for the strains of human papillomavirus (HPV) it targets -- but it leaves 30 percent of HPV strains that cause cervical cancer untouched. And it does not prevent all cases of genital warts either. So it is largely effective. But it does not completely eradicate the disease.

Sprigg also believes that parents should determine whether or not their young girls get the vaccine -- that it should not be mandatory. Mandating the vaccine might be in order if HPV was spread through blood or casual contact. But it is not -- it is spread by sexual contact. And families of young girls might best address this issue through education on behavioral issues alone, without interference from the government.

The wonder of the cervical cancer vaccine is not in question by this writer and the council he represents. But there is often a full picture that lingers behind good news and sensational headlines. And Peter Sprigg offers his take on what he believes lingers behind.

My brother-in-law came up to me tonight with his iPod and handed me his headsets. A cue to put them on, I guessed -- and so I did. A song played and right away I liked what I heard. It was the exact type of music I like -- with a grungy, rock kind of sound. I figured Jack knows what I like and was sharing a new song with me. Which he was -- but there was something more to it. It wasn't just a good song -- it was a good song about cancer, with a message of hope and strength and living through the struggles of a life that has been shaken. Written by Scott Leger of the Austin-based band wideawake, Maybe Tonight, Maybe Tomorrow is dedicated to the millions of people affected by cancer -- those who have lost, those who have survived, those who fight and volunteer and support and research and raise awareness and give and inspire. And for those without cancer too really. For anyone who is faced with forces that threaten the most precious of assets -- time.

Lori is driving across the country trying to raise money -- $9,490 to be exact -- for breast cancer research. One dollar for every day that her mother battled breast cancer. And she is close. She has already raised $8,629.40 through sponsors and donations and has traveled a whopping 6,874 miles since she first hit the road in May. She's been through California and Nevada and North Dakota and Utah and Wyoming -- among other places. She camps and hikes and canoes and stops to see friends along the way. Like the friend she will visit today in Minnesota -- a friend who is surviving breast cancer. She stops at roadside attractions and restaurants and charming little overnight resorts. She stops for photos and to write on her blog -- and through it all, she reflects on the mother she lost almost one year ago. And she raises hope for others fighting breast cancer by giving 100 percent of her donations to The Breast Cancer Research Foundation. I am impressed. I am honored. I am in awe of what Lori is doing. Because I know I could never do it.

I don't like to travel -- and anything more than a three-hour trek in any direction, by any mode of transportation, is too much for me. And while I have traveled in my life to faraway places -- England, France, Germany, Italy, and more -- I do not enjoy any part of the process that gets me to and from my destinations. I'm not sure why. I just don't like it. But I admire those who venture to distant lands. And those who find excitement in a spontaneous trip. And those who tackle the long road across state lines for the pure thrill of it. And those -- like Lori -- who do it so others can benefit. So others can survive the disease that takes so many lives. The disease that took Lori's mom.
