Suppose that, during your next doctor's visit, you look at your medical record and your doctor has written "53- year-old diabetic white female, here today for a check-up." Would you be bothered by that description? Probably not. Your doctor is just discussing your medical condition, right? But what if, instead of "diabetic" the note read "53-year-old obese white female?" How would you feel now? Hurt? Angry? Sad? Would you think, "Why is my doctor being so mean?"
For many, the term "obese" brings to mind a massively overweight individual (like "Fat Albert" in the old Saturday morning cartoons). In reality most obese people don't look like Albert.
Obesity is a medical term
Obesity is actually a precise medical term that is based on a measure of body fat called the Body Mass Index (BMI). The BMI is calculated from a person's height and weight. In general, a higher BMI indicates a higher amount of body fat. Adults with a BMI between 18 and 25 are in the "healthy" body fat/weight category. People with a BMI between 25 and 30 are considered overweight, and a BMI greater than 30 signifies obesity. Many people who view themselves as having a "normal weight" (or at most "pleasingly plump") are shocked when they do this calculation and realize that 180 pounds on their 5 feet 6 inch frame means they are medically obese.
Our obsession with body image creates an emotional context for obesity that doesn't exist for most other medical issues. But make no mistake about it - obesity is a medical condition, and like other medical problems it has important long-term implications for health and well-being. More...

How often do you think a family conversation about cancer occurs? The truth is, not nearly often enough.
Colorectal cancer (often called simply "colon cancer") is cancer that develops in the colon or the rectum, and it's the third most common cancer in the U.S. While most people diagnosed with colon cancer do not have a family history the disease, people who have this cancer in their family have a significantly higher chance of being diagnosed. The good news is that colon cancer is one of the most preventable cancers, and this prevention can work even for people who are at high risk of the disease. More...

Did you hear the one about the hot dog and the rotisserie chicken? Recent news reports suggest that, at least when it comes to cancer, the hot dog may be the better choice.
But don't reach for the mustard and relish just yet.
Researchers at Kansas State University, with funding in part from the American Meat Institute and the National Pork Board Check-off, tested the heterocyclic amine (HCA) levels of a variety of popular ready-to-eat meat products: hot dogs, deli meats, bacon, pepperoni and rotisserie chicken. HCAs are chemicals that are formed in meats when they are cooked at very high temperatures. Studies show that these chemicals can damage DNA and cause cancer in animals. It's not clear how much they may contribute to cancer risk in people. Even so, the American Cancer Society recommends cooking meats with methods that create fewer HCAs, such as baking or poaching.

There's been a lot of news lately about cancer-sniffing dogs after a new study by Japanese researcher Hideto Sonoda and his colleagues was published in the medical journal Gut. So we couldn't help but wonder, is that possible?
If you haven't heard about it, the recent study suggests that specially-trained dogs can identify the scent of volatile chemicals (those that evaporate into the air at room temperature) present in colon cancer. More...

Embarrassing! Painful! Disgusting!!
These are some of the words that come to mind for lots of folks when they think about getting tested for colorectal cancer. Let's face it - this involves a part of the body and bodily functions that people don't talk about in polite conversation. Hopefully I can convince you that they (and you) need to get past this attitude and get on with testing.
Cancers of the colon and the rectum (the last sections of the digestive system) are extremely common. In fact, they're the third most common cancer in US men and women. The good news is the rates of this disease have been falling steadily over the past 20 years, and a big part of the decrease is directly related to testing for colorectal cancer. You see, not only can testing help find the disease early, when it's highly treatable, but testing can actually help to prevent the disease! That's because most colorectal cancers start as a small, non-cancerous growth called a polyp. Finding and removing these polyps stops cancer before it starts.
