Obesity-related cancers, typically seen in older adults, are becoming more prevalent among young people in the United States, according to a US study. Moreover, they are developing more and more early.
In the United States, obesity-related cancers are reported to be increasing and appearing earlier and earlier. This is the alarming finding of a study by the American Cancer Society published in The Lancet Public Health on Monday, February 4th. Researchers examined data on 12 obesity-related cancers and 18 non-obesity-related cancers. They found an upward trend among adults aged 24 to 49 between 1995 and 2014.
The scientists have analyzed twenty years of data on the incidence of 30 cancers in 25 states, based on the Cancer in North America database, covering 67% of cases in the US population. In the end, the risk of cancer has increased among young adults for half of obesity-related cancers: colorectal cancer, endometrial cancer, gall bladder cancer, kidney cancer, bone marrow cancer, pancreatic cancer and pancreatic cancer and multiple myeloma. Most of his illnesses are usually seen in older patients in their 60s.
For example, the risk of colorectal, endometrial, pancreatic and gallbladder cancer in Millennials was about twice as high as that of baby boomers at the same age. “The risk of cancer is increasing in young adults for half of the obesity-related cancers, with the increase steeper in progressively younger ages,” said Ahmedin Jemal, lead author of the study interviewed by CNN.
In contrast, among the youngest, rates of non-obesity-related cancers have decreased or stabilized, including those associated with smoking and infections. Only gastrointestinal cancer and leukemia have increased in these age groups.
“Excess weight is a known carcinogen, associated with more than a dozen cancers and suspected to promote several others,” say the researchers in a statement. Increasing evidence supports an association between childhood and adolescent obesity and the increased risk of colorectal, endometrial, pancreatic and multiple myeloma cancers. The World Health Organization (WHO) has described obesity as a “growing epidemic,” with nearly two billion adults considered overweight worldwide.
A poor diet, rich in processed foods, and a lack of physical activity have contributed to the fact that the young people weigh more and more heavily with the generations. According to British research, 7 in 10 people born between the early 1980s and the mid-1990s will probably be overweight or obese by mid-thirties or mid-forties. Only 5 out of 10 baby boomers were at the same age.
