AND SAYS THE YOUNGEST PERSON HE’S TREATED FOR COLON CANCER WAS 27. COLON CANCER DEATHS ARE ON THE RISE IN YOUNGER ADULTS MAINLY BECAUSE THEY DON’T GET TESTED SOON ENOUGH. >> STUDIES SHOW THAT YOUNGER PEOPLE ARE LIKELY TO BE DIAGNOSED WITH LATER STAGE COLORECTAL CANCER BECAUSE THEY ASSUME THEIR SYMPTOMS ARE ASSOCIATED WITH SOMETHING ELSE AND THEIR CANCER TYPICALLY PROGRESSES. >> COLON CANCER DEVELOPS IN THE RECTUM AND EFFECTS THE DIGESTIVE TRACT SYMPTOMS INCLUDE RECTAL BLEEDING AND ABDOMINAL COMFORT. SIGNS THAT PEOPLE MIGHT ASSOCIATE WITH OTHER ILLNESSES WHICH IS WHY DR. BHAGWANDIN IS STRESSING THE IMPORTANCE OF EARLY SCREENING ESPECIALLY FOR AT RISK INDIVIDUALS. >> BLACK PATIENTS ARE 20% MORE LIKELY TO DEVELOP COLON CANCER AND NEARLY 40% WILL ULTIMATELY DIE FROM IT SO I THINK IDENTIFYING HIGHER RISK POPULATIONS IS IMPORTANT ON WHEN TO SCREE >> THE AMERICAN CANCER SOCIETY RECOMMENDS PEOPLE TO START SCREENINGS AT THE AGE OF 45 BUT DR. BHAGWANDIN SAYS IF YOUHAVE ANY SYMPTOMS YOU SHOULD REACH OUT TO YOUR DOCTOR AS SOON AS POSSIBLE.

Here’s how much physical activity a day cuts your risk of colon cancer

How much exercise you were logging during your teen years matters, too.

Think back to what you were doing as a teen. Were you on the pounding the trails on the cross-country team? Maybe sprinting back and forth on the soccer field?How active you were then — and how you’ve maintained it now — is important when gauging your risk of colorectal cancer, a recent study suggests. Physical activity during adolescence can lower risk of the disease, and if you continue moderate, daily physical exercise well into adulthood, the results are particularly dramatic. Published in the British Journal of Cancer, the research looked at data from the Nurses’ Health Study II, one of the largest investigations into major chronic disease risk. Researchers analyzed data on 28,250 women aged 25 to 42, examining the long-term effects of physical activity, nutrition, and hormones, among other health factors.They found that those who reported at least an hour of physical activity per day from age 12 to 22 had reduced risk of adenoma — polyps considered a precursor of colorectal cancer —by 7%, compared to those with lower activity amounts.Physical activity that started in adulthood reduced risk by 9%.But for those who started being active as teens and continued that hour-plus-daily activity streak? They had the biggest benefit of all: They reduced their adenoma risk by 24%. The takeaway here is that there’s a cumulative effect of physical activity as you age, according to study co-author Leandro Rezende, D.Sc., Ph.D.(c), of the University of Sao Paulo in Brazil.Starting physical activity at any age is advantageous for numerous reasons, including better colorectal health, he told Runner’s World, and the longer you maintain that activity, the better off you’ll be.“Physical activity reduces the risk of colon cancer by several biological mechanisms,” he said. “Weight management and control are likely the most important, because it impacts insulin resistance and inflammation that are involved in the promotion and progression of cancer.” Although this study didn’t look at whether activity intensity or frequency made a bigger difference, Rezende said previous studies have shown that moderate-to-vigorous activity is associated with lower bowel cancer risks, as well as lower risk for breast and endometrium cancers. Plus, recent studies suggest you don’t need to get your exercise in big exercise blocks, or even in 10-minute-plus increments, as previously believed. Even small bursts of activity can add up.“The more activity you get, especially if you do it every day, and at higher levels, the more of an impact on cancer prevention you’re likely to see,” said Rezende.
