Half of all new diagnoses are in people aged 66 and over, the report said.
In the report, the American Cancer Society found that the medieval age of people diagnosed with colorectal cancer in 1989 was 72૨. It remained that way until the early 2000s and then dropped to 66 by 2016.
“This report is very important because it provides a quick overview of the current colorectal cancer burden, but also provides a window into the future,” she added, adding that if the increase in young adults continues, doctors should be aware of the unique. Challenges in this patient population – such as the need to maintain reproductive and sexual function, as well as the risk of long-term treatment effects due to their longevity. “
An epidemic of obesity can be a factor
The report includes data from colorectal cancer cases and others, including data from the National Cancer Institute and the US Centers for Disease Control and Prevention.
Based on the analysis of the data, the researchers found that cases of colorectal cancer have been increasing in people under the age of 50 since the mid-1990s.
From 2012 to 2011, the incidence rate in that age group increased by 7.5% year-on-year and included tumors from both the colon and rectum, the study found.
Researchers have found that the incidence of colorectal cancer in adolescents between the ages of 20 and 64 decreased during the 2000s, then relaunched and increased by 1% annually between 2011 and 2016. In adults 65 and older, the study found that the incidence of colorectal cancer decreased rapidly. It remained the same during the 2000s and declined to 3.3% per annum from 2011 to 2016.
Siegel said the decline in older adults is largely due to increased screening, but the cause of the growing incidence in younger age groups is still unknown.
“The obesity epidemic is probably contributing, but it doesn’t seem to be the only cause,” he said. “Diet has a big impact on the risk of colorectal cancer and a lot of research is going on looking at how we consume a variety of things, including drugs like antibiotics that affect intestinal health, especially their role in determining the microorganisms that make up our microbes. . “
Doctors should proceed with younger patients
The analysis from 2008-2017 found that colorectal cancer mortality rate was 65% for adults aged 65 and over, and 0.6% for adults aged 64 to 0 – but increased to 1.3% for those under 50 years of age.
According to statistics, between 2015 and 2016, the Asian / Pacific Islands had rates of 30 cases per 100,000 people and whites 38.6, blacks 45.7 and Alaska 89 people.
The research had some limitations and scientists were unable to determine exactly why there was a definite decrease or increase in colorectal cancer in certain age groups.
Although researchers were able to make some predictions about future trends, an estimated 7% of deaths from colorectal cancer in 2020 could be estimated at 50%, or 6,640 deaths, in adults younger than 0 years.
In this analysis, the U.S. The estimated 147,950 cases of newly diagnosed colorectal cancer in India are also about 12%, or 17,930 cases, diagnosed in adults under 50.
Siegel said the analysis could “create more consensus to start screening at age 50.”
“In addition, this should be a wake-up call for clinicians about the timely follow-up of younger patients present with clinical cancer symptoms,” he said.
