New studies confirm that in seven countries, including Canada, the influx of adults under 50 years of age develops colon and rectal cancer.
World Health Organization researchers surveyed colorectal cancer among 143 million people in seven high-income countries (Australia, Canada, Denmark, Norway, New Zealand, Ireland and the United Kingdom) and found that the incidence of diseases had declined overall. over the past 10 years, but has risen dramatically among people under the age of 50.
Colorectal cancer refers to both colon cancer and rectal cancer. This is the third largest cancer in the world, with 1.8 million new cases reported worldwide in 2018.
The findings recently published in the The Lancet, showed a 3.4% increase in colorectal cancer among Canadians under 50 and a decrease of 1.9% among subjects aged 50 to 74 years. The study shows that promotions are more noticeable among women and girls.
This is the case with Christine Benson, 38, from Port Hope, Ontario, who was diagnosed with Stage 3 colon cancer two years ago.
"I think the doctors were definitely surprised just because of my age and I had no family history," she told CTV News. "They were definitely shocked and I was more shocked."
For Dr. Shadi Ashamala, a surgical oncologist at the Sunnybrook Health Center in Toronto, which specializes in colorectal cancer among younger patients, the study confirms what he sees on a regular basis.
"My youngest patient was 18 years old, but I managed to deal with patients in their late teens, their number in the 1920s and a stunning number in the 1930s and 1940s," he said.
Researchers suggest that obesity, red meat consumption, smoking and physical activity may be responsible for the increase in colorectal cancer among young people, but further research is needed to confirm these assumptions. For Benson, worries are not real explanations.
"The main concern is that no one can tell us why or where it comes from," she said. "People would say," They eat well and you are fit and trained, "and I do not actually have parts of my lifestyle that would lead to cancer in my life. That's a little concerned. "
In Canada, screening for colorectal cancer usually begins at age 50, but researchers are proposing to review the guidelines to screen young people at a younger age. They also suggest that people should remain vigilant at any age and look for any changes in bowel movements, signs of rectal bleeding or lump in the abdomen, all of which are potential symptoms of colorectal cancer.
"We need vigilance from each individual to pay attention to their symptoms, see their stools, not to worry about making changes to the stools or their gut habits to their doctors and investigating them," Ashmail said. treating this disease better results we get. "
Ashamalla adds doctors play a role in keeping the eye for the symptoms among younger patients and treatment should be tailored to younger patients.
"We have to take these symptoms as seriously at the age of 35 as it is in the age of 60," he said. "Understanding what is unusual and understanding that abnormal can mean colorectal cancer, despite the age of the patients and the study."
