Under 50? Have a colon?

A U.S. study on colorectal cancer suggests earlier screening for younger adults

The January 2016 study published in the medical journal Cancer found that one in seven, or 14 percent, of colon and rectal cancers in the U.S. are diagnosed in patients younger than the age of 50. That’s the age when most Americans (and Canadians) are advised to begin routine screenings. The authors of the study suggested U.S. adults may want to consider screening earlier. Critics of the study said the yield of screening will be low since young people are less likely to get colorectal cancer than older people.

At the end of the day, it’s all about choice. You are in control of your own health and you have the option to get screened when it is right for you.

Canadians and colorectal cancer

Colorectal cancer is the third most commonly diagnosed cancer in Canada, the second leading cause of cancer death in men, and the third in women.

The good news: colorectal cancer is one of the most responsive cancers to early treatment, with a five-year survival rate of 90 percent. Even better, when a polyp is detected early (a polyp is the small growth on the lining of colon or rectum), your medical team can stop the cancer before it starts.

Younger Canadians and colon cancer

In Ontario, 8.8 percent of all male colorectal cancer cases occur in men under age 50. The statistics are similar for Ontario women. Individuals in these age groups are generally not eligible for provincially-funded screening unless they have symptoms or have an affected first degree relative.  This is interesting since U.S. screening guidelines start at age 45 for certain high-risk groups. These groups have lower cancer rates than certain populations in Ontario, even though the province’s screening guidelines* remain at 50.

Medcan respectfully maintains its position as a destination for early cancer detection with colonoscopies for individuals above and below age 50.

How to conquer your colonoscopy

Here are a few tips to help you prepare for the experience:

Better prep, better visibility for your doctor. This means there is a better chance you will find something, if there is something to be found.

No need to overdo the laxatives. The quantity of laxatives has decreased significantly in recent years: only three 5 ounce servings.

They are more tolerable now, too. Most clients don’t find the taste to be unpleasant. Sucking on a hard candy or rinsing with mouthwash can also make it more palatable.

You can drink a beer. You’ll have to drink at least two liters of clear liquid while taking the laxatives like apple juice, sports drinks or any drink you can see through (that’s not red). If you’d like to enjoy a beer or glass of white wine, that’s okay. But one is enough as the prep will dehydrate you.

Your nurse loves to talk polyps. We welcome all sorts of questions as you prepare ahead of the procedure.

*New guidelines, do they apply to you?

The screening guidelines for Canadians under the age of 50 with a family history (first degree relative) is every five years, with initial screening recommended 10 years prior to the age the first degree relative was diagnosed.

The updated guidelines released last month in the Canadian Medical Association Journal apply to adults ages 50 to 74 and recommend patients undergo fecal occult blood testing (FOBT) every two years, or a flexible sigmoidoscopy every 10 years (this procedure reviews only the lower portion of the colon and rectum, whereas a colonoscopy reviews the entire colon).

Outlook: DNA technology

We are monitoring the development of emerging technologies, including non-invasive colon cancer screening tests based on stool DNA, which may address the inconsistencies and unreliability of the FOBT. At this time, in terms of prevention, a colonoscopy remains the gold standard for all ages.

The value of flavour

It’s time to take back flavour and, in doing so, our well-being

As much as we know certain foods are better than others, we gravitate to food that tastes good. Flavour is a huge driver behind our choices. Before the evolution of processed food and other modern agricultural practices, food that tasted good was also good for us nutritionally. But in the past 80 years, real food has lost flavour and synthetic additives have hijacked our brain and taste buds.

I became more aware of this issue when I attended a University of Toronto seminar on nutritional science. Mark Schatzker, the award-winning journalist of The Dorito Effect, provided an eye-opening exposé on why we crave what we do.  His arguments were so compelling that it went on to spur a dietitian-wide book club at Medcan.

Schatzker says that flavour is nature’s way of telling us what is nutritionally valuable – he calls this concept nutritional wisdom.  Flavour molecules are associated with certain nutrients, which our body uses as a map to guide us back to what we need.  But with the growth of ultra-processed foods, our bodies have lost this wisdom. We now crave flavours that are linked to foods of no value. Grapes, for example are nutritious, but grape soda is not.  As a species, we are lost and confused.

Pledge to eat more flavourful food

While we may feel the odds are stacked against us, there are ways we can reclaim flavour – and the nutrition we need for our well being:

Detox slowly from the junk and read labels

Many unhelpful food cravings are acquired and you can like healthier options in time.  If salt and sugar are an issue for you, reduce their intake gradually. The less you have, the less you crave.  Read labels to avoid artificial sweeteners and flavours.  It’s unfair competition to pit fruit against an artificial sweetener, which can be up to 600 times chemically sweeter than sugar.

Purchase heirloom fruits and vegetables

Heirloom fruits and vegetables have been farmed using open-pollination instead of intentional hybrid/cross-breeding techniques.  Through natural selection, the strongest genes are carried forward, resulting in a variety of flavours and colours.  Try heirloom tomatoes or heirloom purple carrots for a different spin on a salad – see if you can taste the difference.

Spice things up

Herbs and spices contain secondary plant compounds, which are chemicals that protect plants from parasites, insects, and animals. These chemicals, although toxic to some organisms, are advantageous to us and help ward off damage to our cells.  Oregano has strong antibiotic and antifungal properties; rosemary and thyme marinades can reduce cancer-causing compounds, such as HCAs and PHAs found in charred and grilled meats.  As Hippocrates is quoted as saying, let food be thy medicine.

Each March, the Dietitians of Canada celebrate nutrition month.  This year’s theme is to take the 100-meal journey, transforming small, sustainable changes into life-long, healthy behaviours.

Pleasure and purpose: It's time to demand flavour in our food to feed our well-being

In the past 80 years, real food has lost flavour and synthetic additives have hijacked our brain and taste buds.   Flavour molecules are associated with certain nutrients, which our body uses as a map to guide us back to what we need.  But with the growth of ultra-processed foods, our bodies have lost this wisdom.
