Scientists reveal reason behind ‘steep’ increase in colon cancer cases among young people

According to a new study, the incidence rates of colon cancer in the United States increased by about 50 percent per year.

An investigation by the American Cancer Association (ACS) found that the diagnosis of local stage colorectal cancer (CRC) in adults aged 45 to 49 years in the USA between 2019-2022 after a stable tendency of 15 years found that the diagnosis of local cancer (CRC) increased significantly.

Cases between this age group increased by one percent annually from 2004 to 2019, but this increase increased from 2019 to 12 percent per year.

In people aged 20 to 39 years, CRC incidence has increased by 1.6 percent and 40 to 44 and 50 to 54 years since 2004 since 2004, two percent and 2.6 percent since 2012.

In general, there was a 50 percent relative increase in diagnoses from 2021 to 2022 and rose from 11.7 per 100,000 to 17.5 cases per 100,000 people.

This upright increase was directed by the detection of local stage tumors, which increased 19 percent for colon cancer from 2019 to 2022.

Elizabeth Schafer, the chief author of the study, attributed the increase in colon cancer diagnoses to new suggestions that reduce the screening age of the disease.

The recommended age to start CRC scan was reduced from 50 to 45 by ACS in 2018 and followed by the US Preventive Services Mission Force (USPSTF) in 2021.

Local or early stages indicate that cancer is limited to the original region, indicating that the cancer begins, not spread to other parts of the body and usually does not have symptoms.

If the colon cancer is detected in the early stages and treated, the five -year survival rate is approximately 90 percent, while it is around 60 percent if it is diagnosed in advanced stages.

Canada, where the US has already been set to 50 years, has a lower colon cancer screening age than some other Western countries, including England in the UK and the UK, which reduced it from 60 to 50 years in 2021.

Early starting colorectal cancer has become the leading cause of cancer -related deaths for men under 50 years of age and the second leader of women under 50 years of age.

More than 50,000 Americans are expected to die of colorectal cancer this year, while 150,000 will be diagnosed with disease.

Although it is known that the disease is linked to obesity, experts stated that the disease occurs in harmony and healthy patients.

Some experts believe that the statement should be in the environmental factors that young people are exposed to more than previous generations.

Although there is no ‘cigarette weapon’, there is more than one theory. Among them, modern chemicals, germs, pollution and a recent study of diets, even found the increase in exposure to E. Coli in foods.

For the last ACS work published on Monday American Medical Association Magazine (Jama)The researchers analyzed the CRC cases identified between 2004-2022 among adults between the ages of 20 to 54 in 21 geographical regions of the National Cancer Institute’s surveillance, epidemiology and recent results (Seer).

Cases are listed according to the age of cancer and according to diagnosis.

Advanced stage disease has continued to increase upright in the last twenty years.

Advanced CRC incidence has risen from 1.7 percent to 2.9 percent since 2004, among the adults under 45 years of age, and faster in the last decade of 45 to 54 years.

To support these findings, another ACS LED work published today Jama Among the adults aged 45 to 49, CRC screening increased by 62 percent from 2019 to 2023.

Jessica Star, the chief writer, who is the assistant of cancer risk factors and screening surveillance research in ACS, said, not to see the increase in colorectal cancer screening among young adults, but also how to rise in the previous stage diagnosis, as stated in other ACS LED paper. ”

However, we still have a long way. Colorectal cancer screening was insufficient at the age of 45-49 and did not increase equally with both the education and insurance status. ‘

For this study, scientists analyzed the data of more than 50,000 individuals from the National Health Interview Research and compared the changes in CRC screening from 2019 to 2023 in the 40 to 44 age group; 45 to 49; 50 to 54; 55 to 64; and 65 to 75 years.

Data were set by age, gender, race/ethnic origin, education and region.

Monica, who did not give her surname, found it difficult for doctors to listen to health worries. Australia, who still lives in Croatia, was diagnosed with stage 4 colon cancer at the age of 31 last year.

Researchers found that the current CRC screening increased by 20 percent in 2021 and 37 percent in 2023.

The results of the study showed that colonoscopy screening between 45-49 years increased by 43 percent and stool-based tests increased from 2019 to 2023.

Scanning has increased significantly from 2019 to 2023 in every racial and ethnic group, but remained less than high school education and remained unused.

Lisa A. Lacasse, President of ACS’s defender subsidiary, Lisa A. Lacasse, President of the American Cancer Association Cancer Action Network (ACS CAN), said, “These studies also show the importance of people who have access to comprehensive health insurance covering evidence -based preventive services”.

When more than 2 million people are expected to be diagnosed in cancer in the United States in 2025, it is more important to ensure that everyone can reach the necessary demonstrations.

‘ACS will continue to defend at the state and federal level to expand access to everyone, because it is not just a good policy, but a life -saving.’

Doctors say that those who have symptoms of colon cancer or who are worried about the disease and who are under 45 years of age can still be screened in health insurance.

The insurance will see the scanning of tests for this group as a test to investigate certain symptoms instead of a preventive scan.

The cost of colonoscopy from mobile is between $ 1,250 and $ 4,800-but this situation changes significantly by the state.
