I think all the time about how I'm treating my body. Just yesterday, while making a tuna sandwich I wondered if I was using too much light mayonnaise. I considered the fact that tuna contains mercury, that I should monitor how much of this product I consume.

How much is too much anyway?

I worried that my tuna was slathered on white bakery bread, a true diet no-no, and I found solace in only two items -- my hand-picked strawberries and the water I poured in my cup.

Wait, the strawberries were pretty plump, ripe, red, and juicy -- an indication they were possibly pumped full of hormones and sprayed with pesticides before I washed and gulped them down.

How did I do overall at lunch? I think maybe not so good. I did run 2.5 miles and completed 20 push-ups, a bunch of sit-ups, and few core exercises. Maybe I come out balanced in the end. Maybe not.

I think about this sort of stuff every day because of cancer. I've already had it -- and I don't want it again. So I try to eat right. I exercise. I don't smoke. I don't drink alcohol. But here's my dilemma: I did all this before my cancer diagnosis (with the exception of an occasional drink), and the disease still lived in my body -- maybe for many years before I knew it was there. What should I do differently now when I didn't do all that bad before?

Shall I exercise all day long? Eat only the most pure and untainted of foods? Somehow that doesn't seem much like living. So I suppose I'll keep on doing what I do every day -- living in moderation -- with hopes that I've had my one and only brush with cancer and that the bout I had was caused by something other than how I treat my body.

Here's my problem with health-related advice and wisdom -- it's always changing. And I'm never sure if I'm buying into the right practice. Should I eat low-fat foods, for example, or should I stick with moderate amounts of regular food? Is red meat a good source of protein and other goodies or a direct path to breast cancer recurrence? Will sunscreen save my life or cause malignant lesions to develop on my fair skin?

How about drinking eight glass of water a day? Maybe yes. Maybe no, according to experts who say we get water from sources other than diet alone and while we do need to replace water lost through breathing, urination, and sweating each day, our lost fluids do not total 64 ounces. And it seems we can drink too much water. This can lead to an imbalance of sodium and a condition called hyponatremia.

Vitamin supplements? Eat a good amount of fruits, veggies, whole grains, low-fat dairy, protein, and the right amount of calories and you don't need a multivitamin. But most of us don't eat right. So we probably need one.

OK. Now breathe. Take it all in. Filter it. Use it. Abandon it. As for me -- I'm going with the tactic mentioned above several times -- moderation. Seems to me this approach is the key to both health and happiness.

I had no idea my February 10 post Some children's bath products linked to cancer would spark such great debate. At the very moment I write, the post has received more than 64,000 hits and 70 comments.

I must admit when the comments started rolling in, I was a bit nervous. Even though I merely reported the facts on this topic, had no claim to any of the information, and didn't even share my opinion on the matter, the highly charged words written by so many well-meaning readers made me feel a bit like I was caught in the middle, like I started an argument and needed to jump back in, sort things out, and create harmony among those responding to my words.

But then I realized debate is not such a bad thing. It sheds light on all sorts of valid viewpoints. It educates. It raises awareness. And that's what cancer causes are all about.

Having read all the comments that now are officially assigned to this one post, I am so much more enlightened than when I summarized the story I came across revealing that some bath products contain a bit too much of a chemical called 1,4-dioxane, a probable human carcinogen that is already known to cause cancer in animals.

All I really knew at the time I wrote the post is that the FDA has no regulation over this chemical and that cosmetic companies must monitor themselves. Some don't do such a good job, and herein lies the debate.

Some readers say big deal, what's the harm really in a little extra dash of chemical in a whole tub of water. Perhaps if our children soaked all day for many days in this chemical, cancer might strike. But a quick bath with a tiny trace of 1,4-dioxane is not likely to do any harm. One reader wrote that we shouldn't stress so much about headlines that scare us into believing everything causes cancer, that we'll probably live a whole lot longer just living our lives free of constant worry.

Another camp of readers say a little bit of something bad is still too much. Over the course of a lifetime, how do we know our children won't pay for our mistaken belief that this hype is just -- hype. Some cancer surviving readers wonder if their cancer was caused by their plentiful childhood bubble baths. And some go to great lengths to find natural, organic, chemical-free products, whatever the financial cost.

A few consultants for these natural products left their own comments, claiming to help those consumed with anxiety. Others scolded these business people for capitalizing on the fears of others with products that have not been proved any safer.

There are advocates of moderation who wrote. And individuals seeking more information. And people who located resources for others to investigate.

There is indeed a rich commentary on the link between bath products and cancer that follows one short post I wrote late one night, after my own children were bathed -- with Dove soap and generic shampoo -- and put to bed. And I am indeed happy to know my small contribution on the topic has generated such a powerful windfall of thought and concern.

The International Agency for Research on Cancer researchers have concluded a study indicating that 3.6 percent of all cancer cases worldwide are related to alcohol drinking.

"A causal link has been established between alcohol drinking and cancers of the oral cavity, pharynx, esophagus, colon, rectum, liver, larynx, and breast," states lead researcher Dr. Paolo Boffetta. "For other cancers, a causal association is suspected." According to the researchers of Lyon, France, more than 60 percent of alcohol-related cancers in men were in the upper digestive tract, and approximately 60 percent of alcohol-associated cancers in women were breast cancer.

The researchers also point out that moderate alcohol drinking has been shown to be beneficial to heart health. The American Cancer Society advises that drinking be limited to one drink a day for women and two drinks a day for men to reduce the increased cancer risks associated with alcohol consumption.
