Screening for colon cancer should begin earlier, at the age of 45 instead of 50, due to an increase in colorectal tumors in younger people, said the American Cancer Society on Wednesday.

The new guidelines came after research in patients under the age of 50 had shown an increase in colorectal cancer by 51

percent since 1994 and a concomitant increase in mortality rates.

"When we started this guideline update, we initially focused on screening should begin earlier in racial subgroups with higher colorectal cancer incidence, which some organizations already recommend," said Richard Wender, senior cancer control officer of the American Cancer Society.

Groups known to suffer disproportionately high levels of colorectal cancer are African Americans

"However, as we saw data suggesting a continued trend of increasing colorectal cancer incidence among younger adults, including the American Cancer Society Research that pointed out that this effect would progress with age, we decided to redetermine age to initiate screening in all adults in the US. "

The new guidelines do not specify what kind but includes options such as a traditional colonoscopy – which should be performed every 10 years – or a highly sensitive stool analysis, which could be performed every year to every three years depending on the type.

Regular screening should continue until the next day 75 years old, and "clinicians should discourage individuals over 85 to continue their colorectal cancer screening," as the risk of complications outweighs the benefits at that age

Mysterious increase in cancer

Experts say that it is unclear why colon cancer rates are increasing in younger people.

Studies show that adults born around 1990 have twice the risk of colon cancer and four times the risk of colon cancer have the least risk, the report said in CA: A Cancer Journal for Clinicians, a peer-reviewed journal the American Cancer Society.

Meanwhile, colon cancer rates in humans are over 55 years old, mainly for the treatment and removal of precancerous polyps

According to Elena Ivanina, a gastroenterologist at Lenox Hill Hospital in New York, the 51% increase in colorectal cancer is among the under-50s since 1994 has been an "alarming" trend.

The reason for the increase is currently unknown but may be linked to obesity and sedentary lifestyles, heavy alcohol consumption and chronic inflammatory conditions, all of which are on the rise, "said Ivanina, who was not involved in the preparation of the guidelines.

19659005] She applauded the move to earlier screening, saying that it "will benefit the general public."

Another widely respected medical group issuing screening recommendations, USPSTF, decided in 2016 not to recommend colon cancer screening at 45 , say that any additional benefit would be "modest."

The American Cancer Society urged people to talk with their doctors about what type of screening to do based on risk factors such as family history, diet, alcohol intake, and exercise patterns.

"I would say an actual colonoscopy would consist of several Grounds the best, "said David Bernstein, chief of hepatology at Northwell Health in New York, AFP

" It's the only one of these tests that actually prevents cancer. It allows you to find polyps before they turn into cancer. "
