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.

Numbness is wearing off, and I am beginning to feel twinges of pain surrounding the area where my port was once located. I can't see what was done to me today -- because the area is carefully bandaged -- but I know from what I feel that my skin has been cut and sewn back together. I feel the skin tightening, stretching, pulsing and while it's not terribly comfortable, it's pretty minor compared to the pain of so many other cancer procedures -- like my lumpectomy, my chemotherapy, my nausea, my neutropenia, my allergic reactions to various medications.

So I am fine, following my port removal that was predicted to last a few hours but somehow took most of the day. The actual procedure took just one hour, and the twilight drug that kept me in a peaceful funk allowed me to relax while the port that was tunneled into the tissue underneath my skin was precisely taken from my body. It was an uneventful experience -- except for a few tears that dripped from my eyes during the final moments before my surgery. I think it may have been the power of the moment -- the moment signaling the end of my active cancer journey. Or it may have been the power of support offered by my sister and my three-year-old son who accompanied me today. Or it may have been the power of the response I gave a nurse who had just seen my little guy and asked me if I planned to have more children. My response -- probably not, because of cancer -- seemed a little too final, a little too sad.

It may have been the combination of everything, all adding up over the past two years, that brought tears to my eyes today. But for now, the tears are gone. And the port is gone. For now, my cancer is gone.

Coletta Barrett believed her stomach pains were caused by a gall bladder attack after eating greasy fried food. She excused a tightening in her lower abdomen as irritable bowel syndrome, and she explained blood in her stool as a response to stress. Only after a referral to a gastroenterologist led to a colonoscopy did she learn that the upper portion of her colon was almost completely blocked by a large tumor -- a cancerous tumor. Barrett was diagnosed with colon cancer. Her colonoscopy saved her life.

Barrett never once predicted she might have colon cancer. She thought the disease mostly struck older people. She was just 42. Screening tests are not even recommended until the age of 50. She had no family history of this cancer and had no typical risk factors associated with the disease. She did not smoke, was not overweight, and drank very little. But she did in fact have colon cancer -- shocking as it was -- and doctors believed her tumor had been growing for 18 months before detected. Fortunately, Barrett learned that her cancer had not spread. And she learned a few other things that she now shares as advice -- from her survivor point of view. These tips come from an article about Barrett in the August 1 Women's Day magazine.

• Barrett says, "know your body." And don't ignore or dismiss any changes that occur.
• Don't let embarrassment stop you from seeking help. Some symptoms can be difficult to discuss -- such as change in size and frequency of bowel movements, bloody stool, cramping, and bloating -- but still ask your doctor about them. Early detection is critical, she says.
• If diagnosed with colon cancer, learn as much as you can about the disease -- a well-informed patient has a better chance at a better outcome.

Barrett offers sound advice. And I think it is global advice. Knowing your body, discussing symptoms, and education after diagnosis are key for anyone. For everyone.
