While sitting in the lobby of my hospital's MRI center on Friday -- time for the annual breast MRI -- I found myself a bit irritated by an appointment mix-up that kept me waiting much too long for a procedure that in and of itself is no real treat.

As I waited to bare my breasts and dangle them through square cut-outs on an MRI table, I flipped through a few ancient magazines -- why are lobby offerings so old? -- and as is usually the case when I read just about any publication, out jumped some cancer news.

So maybe the wait was worth it. Without it, I wouldn't have found this enlightening bit of information, this thought for today.

Now I warn you -- this item I am about to share comes from an October 2005 issue of Parenting magazine, so it's a bit outdated. But it still holds some truth. And if you remember nothing else from this message, I hope you'll take to heart this one lesson -- women tend to overestimate their chances of developing breast cancer.

Think about this:

• 46%: What women estimate is their lifetime risk of getting breast cancer
• 13%: Their actual risk

Someone asked me the other day how I continue to come up with topics for my posts. I wish I could say it was a chore to find material on cancer, but it isn't. There is always something to write about -- so much to write about, in fact, that if I had the time and energy, I could write volumes each day.

I find my topics in newspapers, in magazines, and in books. I spot them on television, on the radio, on the internet. I draw from personal experience and from others' experiences. I write and write and write because cancer just keeps on appearing in my life. I wish it didn't.

Cancer is everywhere. And it offers me an endless reserve of material that just keeps stacking up. So how do I come up with topics for my posts? I don't. The topics come to me.

Radioactive cancer patients attending this weekend's Super Bowl in Miami could be in for an alarming experience when they pass through radiation detectors designed to signal the presence of dirty bombs. Such cancer patients -- who have received treatment using radioisotopes and still may have tiny amounts of radioactive material in their bodies -- may want to come armed with letters from their doctors explaining their precarious set of circumstances.

The use of radioisotopes in medicine is growing -- and so is the use of radiation detectors in our security-conscious nation, which means patients are triggering alarms when they are not even aware they are being scanned, doctors and security officials say.

Nearly 60,000 people a day in the United States undergo treatment or tests that leave traces of radioactive material in their bodies, according to the Society of Nuclear Medicine. These traces are not enough to hurt anyone, but they are enough to trigger radiation alarms for up to three months.

Radioisotopes are commonly used to diagnose and treat certain cancers and thyroid disorders, to analyze heart function, and to scan bones and lungs. And many doctors already know to equip their patients with travel cards because of the problems they can encounter in public places.

Nearly 20 million nuclear medical procedures were performed in the United States in 2005 -- up 15 percent from 2001. Clearly, the number of people who could be mistaken for terrorists is quite large. So if you are one of these people -- with the power to create a buzz in a public setting -- get your papers in order so you can quickly confirm your identity as nothing more than a cancer patient.

The technique, known as radioembolization or intra-arterial brachytherapy, uses the vascular system to deliver targeted treatment to the tumor. The tiny glass bubbles filled with radioactive material deliver high doses of tumor-killing radiation directly to the liver tumors.

Liver tumors use a supply of blood that is largely separate from the blood that nourishes normal liver tissue, so very few of the bubbles end up in the healthy liver.

The bubbles are smaller than the diameter of a human hair. The outpatient procedure takes about an hour to complete. The bubbles release over 10-14 days.

Patients may be candidates for this procedure if they are not able to get a liver transplant. Mayo Clinic radiation oncologists are now using this procedure.

I love it when seven of something lands before me, offering me potential material for the Sunday Seven series. In fact, it just happened. And I can't wait to start writing about the Seven Levels of Healing common to cancer patients and those who love them.

I have a new book. It's called The Journey Through Cancer: Healing and Transforming the Whole Person by Jeremy Geffen, MD.

Dr. Geffen knows cancer. He lost his father just three months after a stomach cancer diagnosis. He became an oncologist. He founded a cancer research center. He travels and speaks and writes about health and wellness. And inside the pages of his newly revised and updated paperback, he details the Seven Levels of Healing -- a blend of conventional and complementary principles-- and the true stories of cancer patients who have directly experienced them.

It occurred to me while first flipping through this book that I might read it in its entirety and then write a review of the material. Then I determined it would take much too long for this approach. With two small children, a few jobs, an exercise routine I must revisit, and all the other bits and pieces of life that keep me occupied, this would be quite an undertaking -- the actual reading, the remembering, the writing. Somehow, this would be too much to manage. But small steps. I think I can handle small steps. So this is how it's going to work.

I will present to you in this post the Seven Levels of Healing. I don't know much about them yet -- although by title alone, I am sure I have lived most of them in my own cancer journey. So I will simply lay the groundwork. And then I will start reading. And as I read, I will write. This will be my own one-woman book club -- with an open invitation for new members. Read my posts and reflect on them. Agree. Disagree. Leave comments. Buy your own book. Read with me. Apply what you learn to your own life. Share what you learn with others. The possibilities are endless as I journey my way through this new book in search of peace, clarity, and comfort -- all of which flow from these seven levels.

Level One: Education & Information
Level Two: Connection with Others
Level Three: The Body as Garden
Level Four: Emotional Healing
Level Five: The Nature of Mind
Level Six: Life Assessment
Level Seven: The Nature of Spirit

And so that's what I have to offer for now. I'm sorry to keep you hanging. But rest assured, I am hanging right along with you, eager to find a moment to dive into this book. To sink my teeth into the words, sentences, paragraphs, chapters. To relay it all to you. I can't wait -- to really understand the Seven Levels of Healing.

The Journey Through Cancer: Introduction

I have made on-line visits to Wikipedia many times -- mostly for information on cancer. And what I've found are endless resources, thoroughly-covered topics, and material that is easy to read and easy to understand. Wikipedia, a free on-line encyclopedia -- where readers can participate in editing and changing content -- offers information on just about any topic you can imagine. And here are seven stops you might make in pursuit of cancer-related material.

A chemical found in hard plastics -- such as CD cases, baby bottles, food-storage containers, and even electronics parts -- has been loosely linked to incidences of breast cancer. Popular opinion cautions that if we were not worried about this news yesterday, we should not be worried about it today -- because studies are preliminary and nothing is definitive at this point. But there are definitely two sides to the debate over how harmful these hard plastics may be.

The chemical in question -- a pseudo-estrogen called bisphenol-A (BPA) -- appears to be absorbed by breast tumor cells, according to a new study published in the August 28 issue of Chemistry & Biology. Previous studies have linked small exposures of BPA to prostate abnormalities in mice that suggest a link between the plastic chemical and human prostate cancer. Some studies even theorize that embryonic and fetal exposure might influence mental retardation and birth defects. And because this pseudo-estrogen is a synthetic material that in human cells can trigger estrogenic effects, breast cancer now comes up as a disease that may result from this questionable chemical.

Critics say that average levels of the chemical found in urine is infinitesimally small -- about one part per billion. Some say the results of this research come from in-vitro studies that one expert says can never fully explain human disease. Yet the real crux of the matter, according to another expert, is that we are surrounded by all sorts of chemicals that are pseudo-estrogenic -- not just BPA -- and it's the cumulative effects that we do need to worry about.

I've been wearing a breast cancer bracelet that jingles with charms in the shapes of hearts, with inspiring little messages like Go with your heart. One of the heart charms is a watch. My friend sent me this shortly after my breast cancer diagnosis. I love this bracelet. So I was sad the other day when the glass piece covering the watch somehow cracked and shattered. I only realized this when I tried to check the time and learned that my watch was not actually telling time anymore. So I went for my back-up -- another watch, exactly the same and also given to me as a gift. I replaced my old watch with the new watch and then days later, my new watch was not working. I think water got inside the glass and damaged the battery or the mechanisms -- or something. I'm sure I could repair the watches -- and I considered this -- but then it entered my mind that maybe this is a message that I am okay now without all my breast cancer gear.

A friend of mine told me last year about her friend who was featured in a newspaper article about a program called Buddy Check 12. I read the article online and cataloged the gist of the story in my head. But I didn't do much with the information as I was in the midst of treatment for breast cancer and thought perhaps at a later date, I could better sort through the abundance of resources that were sent my way.
