Cancer experts have spotted a grim new trend. Despite the decline in cancer rates among people over the age of 50, cancer rates among young people have risen sharply in recent years.
The biggest increase was in people aged 30 to 39, whose cancer incidence increased by almost 20% between 2010 and 2019. According to new research published in JAMA Network Open.
And most of the increase occurred among women, with a 4.4% increase in early-onset cancers among women, but an almost 5% decrease in cases among men.
“We’re already seeing young patients,” says Dr. John Rich, director of colorectal surgery at Long Island Jewish Medical Center in Great Neck, New York. told HealthDay.
“In the past, people in their 40s were said to be extremely abnormal, but it is definitely on the rise. [cases] It’s more 30s than it used to be,” Rich added.
The study authors found that certain cancers accounted for most of the increase in young people. For example, breast cancer cases increased by about 8% during the study period.
However, gastrointestinal cancers, including colon, appendix, bile duct and pancreatic cancers, increased by a staggering 15% during the decade of the study, making it the fastest growing type of cancer. It has become.
These new discoveries confirm earlier findings from a March study. Published in Science magazineThe results show that the incidence of colorectal cancer has increased significantly in recent years.
“Since the 1990s, the age-adjusted incidence of young-onset colorectal cancer has increased at a staggering 2-4% per year in many countries, and even more rapidly among those under 30 years of age.” study authors wrote.
And the recent surge in early-onset cancers is due to familiar factors such as obesity, alcohol, smoking, and a sedentary lifestyle.
“Suspicious risk factors may involve an increase in obesity in children and adolescents. It’s also having an impact on social changes,” Hyuna Song, a cancer surveillance researcher at the American Cancer Society, told Healthday.
Another study published last month found that 18 different cancers are associated with obesity or overweight. Specifically, researchers found that people who were overweight in early adulthood (ages 18 to 40) had an increased risk of cancer.
Song also pointed out that lack of physical activity contributes to cancer. In fact, a recent study found that young men with high levels of fitness were more likely to develop cancers later in life, including esophageal, stomach, pancreatic, liver, bowel, kidney, and lung cancers. is known to be low.
Researchers are concerned that as more young people develop cancer at an increasing rate, cancer could pose a problem when they get older, or in the future. .
“The rise in cancer among young adults is significant,” said Sung, who was not involved in the new study. “This should be considered as a precursor to future trends.”
“More efforts are needed to combat early-onset cancer risk factors such as obesity, heavy drinking and smoking,” said study co-author Daniel Q. Huang, Ph.D., assistant professor of medicine at the National University of Singapore. health day.
