My gut hasn't always guided me through life's most difficult decisions and dilemmas. It wasn't until I felt a lump in my breast more than two years ago that my gut kicked into gear and told me something very important.

"It's cancer," my insides told me one week before the surgeon who did my biopsy called.

"It's cancer," the surgeon said. I didn't tell him, but I thought it: "I know."

I also knew prior to surgery that my cancer had not spread to my lymph nodes. My gut told me this too. It also told me the chemotherapy drug Taxol was not right for me -- since my cancer had not spread -- despite the urging of one oncologist that I accept this treatment. I would have gone on gut instinct alone in my rejection of this medication but another doctor weighed in and agreed with my gut, so I had solid backing on this decision.

Many have dismissed hunches like these and have written off those who believe in them as screwballs, says writer Chip Brown in the March 2007 issue of The Oprah Magazine. But as Brown shares after peering into the world of gut instinct, there are 100 million nerve cells in the gut. They run on autopilot, regulate digestion, play a critical role in the body's immune system, and control mood-altering neurotransmitters identical to those in the brain.

The gut is essentially a second brain. It was a "gut feeling" that led Fred Smith, founder of Federal Express, to begin exploring the possibilities of overnight delivery and Howard Schultz, founder of Starbucks, to begin mass marketing coffee. Wall Street professionals make millions on their gut feelings, sportscasters make startling predictions based on gut guidance, and entrepreneurs launch thriving businesses because of the inklings that rumble in their tummies.

You may or may not be a gut thinker yourself. But I've stumbled upon a gut exercise -- thanks to psychotherapist Nancy Napier --and I'd like for you to consider it the next time you find yourself stuck at a crossroads, unsure of where to turn. You never know, the direction you seek may be swirling around in your midsection, just waiting for a call to action.

Think about this:

You are wavering between two choices. Find yourself a quiet, serene place where there will be no disruptions. Now sit down. Take a moment to settle and focus on the issue you want to explore. Then choose one side. Think about this side and notice what happens in your gut. Do you feel a tightening and gripping or a softening and warming? Are the sensations pleasant or uncomfortable? Notice your thoughts. Are they positive or negative? Give yourself some time to feel your gut and your mind responding.

Now shift to the other side. Think about the previous questions, and try to chart what your body gut is saying.

While you may not get a gut answer at first, if you come back with the question several times, you'll likely hear just what your gut wants you to know.

Take it from Bob Greene, the supercoach who helped Oprah get into the best shape of her life, when he says we all can acquire great health and great fitness -- without calorie counting and deprivation and hardship. He details it all in his new book The Best Life Diet, and he shares a series of how-to guides in the January 2007 issue of Oprah Magazine.

One tool Greene offers as we take on the new year is a hunger scale -- to help us avoid eating mindlessly, to encourage us to get in touch with our hunger, to train us away from always watching calories.

The scale goes like this:

10: Stuffed. Approaching nausea.
9: Very uncomfortably full. Need to loosen clothing.
8: Uncomfortably full. Bloated.
7: Full. A bit uncomfortable.
6: Perfectly comfortable and satisfied.
5: Comfortable. More or less satisfied but could eat more.
4: Slightly uncomfortable. Beginning to feel signs of hunger.
3: Uncomfortably hungry. Stomach is rumbling.
2: Very uncomfortable, irritable, and unable to concentrate.
1: Weak and light-headed. Stomach acid is churning.

Greene says we should eat only when we find ourselves feeling 1, 2, 3, or 4. He instructs us to put our forks down at 5 and 6 and wait for our next scheduled meal. For those trying to lose weight, he says stop eating at 5. This is the point at which you're eating less than your body is burning.

I didn't know what was coming when I plopped myself down in the waiting room of an Ear, Nose, and Throat clinic yesterday -- which is a good thing. Had I known what doctors would do to me, I may have run the other way. I may have learned to live with the pain I was experiencing each time I swallowed food. But I waited patiently, aware that doctors would "scope" my esophagus, mildly certain the procedure could be uncomfortable, completely unprepared for the full "scope" experience.

I swallowed a pill on Friday night -- not even a whole pill, just a half of one pill -- and it hurt when it went down my throat. I've had the feeling before, a sensation like the pill got stuck, but the discomfort has always gone away within a few hours. This time, it lasted. It hurt to swallow saliva. It hurt to swallow food. It just hurt. So after three days, I took myself to the clinic -- with the subtle worry that cancer was settling in my esophagus.

I know rationally that every ache and pain I experience is not cancer. But I've had cancer. And so I constantly battle a nagging fear lodged deep in my head that reminds me cancer is always a possibility, that cancer is often a shocking outcome of a routine little test for a simple little health concern.

I do not have cancer. I do not have cancer of the throat, voice box, esophagus, or stomach. That's the good news. The scope revealed -- via a tiny camera that traveled through my body -- nothing but healthy tissue. That makes me happy. The test did not make me happy.

I now know the scope is a long, thin tube that enters the body through one nostril. Ouch. It travels into the throat. Ouch. The patient swallows when it reaches the throat to assist in maneuvering it down further. Ouch. The scope then makes its way past the voice box, though the esophagus, and into the stomach. Ouch. Ouch. Ouch. The travels are all displayed on a monitor, and I actually got a glimpse of these body parts -- during the split second when I was able to control my gagging, loosen my grip on the arms of the exam chair, and open my clinched eyes. So I saw for myself that everything looks healthy -- just before the tube was pulled right back through all these parts, leaving me with a very sore throat.

Now that I am home and have talked with a few people, I hear that some patients are unconscious for this procedure. They are completely unaware of the horrors of the scope. I got a few sprays to numb my nose and throat and drank a thick cocktail of lidocaine -- but I did not get the luxury of unconsciousness. And in the end that is okay. I got to see what was happening. I got to hear the doctor's revelation that nothing major is wrong. I got to witness the wonder of medical technology. I got to prove to myself that I can handle a little discomfort in exchange for a clean bill of health. And I got to learn that I have a bit of acid reflux. And now I have to squash that nagging fear that reminds me of the literature out there suggesting a link between acid reflux and cancer.

Before my radiation for breast cancer, I heard horror stories about the treatment. I heard that I might be extremely tired and severely burned and that I might feel generally unwell for the time it would take to completely zap any and all traces of cancer surrounding my breast. But my own radiation wasn't all that bad -- and really, the worst part of the whole therapy for me was the drive to and from the cancer center every day for seven weeks. It was a hassle, a nuisance, a bother. There were other small annoyances throughout the course of my radiation, but they were minimal -- thanks to some secrets that were shared with me along the scorching path of radiation and beyond. And here are seven of them.
