The incidence of colorectal cancer – colorectal simply encompasses the terms colon and rectal, meaning colorectal cancer affects either one or both of these parts of the body – in young, generally healthy people around the world’s most well-developed countries has increased substantially in recent years.
A new peer-reviewed academic work published by JAMA Network Open, one of the most popular journals in its class, indicates that the incidence of colorectal cancer diagnoses in Canadian males under the age of 50 has shot up an alarming 3.5 percent from 2006 to 2015.
Further, according to the same study mentioned above, which was published by the well-trusted journal earlier today, on Wednesday, July 31, 2019, the incidence of colorectal cancer in Canadian women under the age of 50 rose 4.5 percent from 2010 to 2015.
This study’s findings are nothing short of an anomaly, as colorectal cancer typically only strikes people over the age of 50. What’s even more hard to believe is that the rates of colorectal cancer in Canadian men and women over the age of 50 – not under 50; you read that correctly – have dropped in recent years. The study’s authors credit two reasons for this positive change in older Canadian populations: first, colonoscopies are steadily becoming more accepted as a regular part of older people’s lives, at least if they want to stay healthy; second, thanks to public health campaigns and a general thirst for knowledge from Canadian citizens, older Canadians are becoming increasingly aware of colorectal disease, thereby making them much more likely than ever before to make healthy lifestyle changes and subject themselves to screenings more frequently than in the past.
Canadians aren’t the only people to have experienced such increases in their young people’s rates of colorectal cancer. Last week, a study hailing from researchers at the University of Texas at Austin found that the proportion of new diagnoses of colorectal cancer in people aged less than 50 years as compared to their older, above-50-years-of-age counterparts was just 10 percent in 2004, though it rose significantly by 2015, all the way up to 12.2 percent.
Further, the study published by the University of Texas at Austin faculty found that younger people who suffer from colorectal cancer are more likely to suffer from more advanced, rapidly-spreading forms of colorectal cancer than their older counterparts.
A lack of fiber in people’s diets, obesity, and leading sedentary lives are three things that are currently more common than in previous generations, each of which is known to increase the risk of colorectal cancer.
