PanARMENIAN.Net – Rise colon the younger cases seen in the United States are also found in richer countries around the world, according to WebMD.
In the decade leading up to 2014, the number of cases of colon cancer among people under 50 years of age increased by 3% per year in Denmark, New Zealand, Australia and Canada and 1% per year in the UK.
The increase is most pronounced among those aged 20-29, a team led by Dr. Marzie Aragiby the International Agency for Cancer Research in Lyon, France.
Among twenty-one cases, cases of colorectal cancer increased by 18% per year in Denmark and 11% in Norway, according to a study published on May 16th in Lancet's gastroenterology and haematology.
"Although the incidence of colorectal cancer in adults under the age of 50 is much lower than in older adults, our findings are a concern and emphasize the need for action to counteract the growing severity of the disease in younger adults. news message.
The increase in the incidence of young people contradicts the reduction of colorectal cancer among people over 50 years of age, the researchers said. For example, between 2004 and 2014, cases of colorectal cancer fall every year among people over 50 – 2% in Australia and Canada, 3% in New Zealand, and 1% in the UK.
Colon cancer remains a major global killer. According to the research team, nearly 2 million cases of colorectal cancer have been diagnosed in 2018 alone, and the disease has claimed 881,000 lives worldwide.
But why does it invade the young? According to Araghi, the increase is probably due in part to an increase in some risk factors, particularly obesity and poor nutrition.
On the other hand, he said, reducing colon cancer in people over the age of 50 is most likely due to better screening tests or a colonoscopy that wounds tumors early.
Dr. David Bernstein is the head of haematology and gastrointestinal specialist at Lenox Hill Hospital in New York. Reviewing the new report, he said that such data has already changed medical practice in the United States.
