TEXAS, July 23 – A new US study shows that colorectal cancer rates among US adults under 50 are on the rise.
Conducted by researchers from the University of Texas at Austin, this new study examined information gathered from the national cancer database registry, which includes more than 70% of new cancer cases in the United States. United, to examine trends in colorectal cancer. since 1970.
The results, published in CANCER, a peer-reviewed journal of the American Cancer Society, has shown that the number of American adults diagnosed with colorectal cancer in the under-50s has continued to increase over the last decade from 10% in 2004 to 12.2% in 2015.
In addition, 51.6% of people under age 50 were diagnosed with colorectal cancer at a later stage (stage III / IV), compared to 40% of people over 50 years of age.
African-American and Hispanic adults younger than 50 years also had higher rates of colorectal cancer than non-Hispanic whites.
Colorectal cancer diagnosis rates among young adults have also increased based on income levels, although the highest rates of diagnosis are in the highest income category.
"Several studies have shown that the rate of colorectal cancer in young adults has been increasing slowly in the United States since the 1970s, but for practicing physicians, it appears that we are seeing more and more young people with colorectal cancer now even 10 years ago. a long time ago, "said Dr. Boone Goodgame, lead author. "Until last year, the guidelines recommended screening for colon cancer from the age of 50. Today, many guidelines recommend screening at age 45, but most doctors and patients do not seem to follow these recommendations. "
Dr. Goodgame pointed out that the cause of the increase in colorectal cancer rates in the under-50s was still unclear, but he pointed out that new research suggested that this might be due to a combination of increased body weight and changes in gastrointestinal bacteria.
Previous research has also linked colorectal cancer with too much sedentary time, especially television, too much alcohol, too much processed meat and a lack of exercise.
A healthy and balanced diet, including nuts and lots of whole grains, increased physical activity and low alcohol consumption, has been badociated with lower risk.
The American Cancer Society guidelines suggest that middle-aged adults aged 45 and over be screened for colorectal cancer on a regular basis. – AFP-Relaxnews
