[NTD, Pechino, 12 settembre 2022]A new study finds that since 1990 adults under the age of 50 around the world have suffered fromcancerThe number of people has increased dramatically.
cancerThat prevalence is increasing in modern society is not a revolutionary idea.According to ScienceAlert, a team of researchers at Harvard University realized that since the 1940s and 1950s, patients withlate-onset cancernumber has increased. Late-onset cancer is cancer that develops after age 50.
But what the research team wanted to study was,early onset cancerCancer rates among people under 50 are also on the rise. To do this, they looked at people born in the 1950s and 1960s and looked at their cancer rates since the 1990s.
They looked at data from 14 cancers: breast, colon (CRC), endometrial, esophageal, extrahepatic bile duct, gallbladder, head and neck, kidney, liver, bone marrow, pancreas, prostate cancer, gastric and thyroid cancer.
Global cancer data shows that the prevalence of all of these cancers increased between 2000 and 2012 among adults under the age of 50.
“The incidence of late-onset colon cancer (people born in the late 19th and early 20th centuries) began to increase in the 1950s, while the incidence of early-onset colon cancer (people born in mid-20th century) did not begin to increase, until the early 1990s, ”the researchers wrote in their paper.
So what changed that made post-90s 50s more susceptibleearly onset cancerWool cloth?
One of the biggest changes is the increase in screening, which has undoubtedly helped improve the detection rate of early-onset cancers.
But that alone doesn’t seem to fully explain the change, especially since some early-onset cancers are on the rise even in countries without screening programs, the team noted.
“There also appears to be a real increase in early-onset incidence in different types of cancer,” the team wrote in the paper.
In addition to being better at detecting early-onset cancers now, there is evidence that the “transition” in cancer rates actually happened earlier, around the middle of the last century.
In fact, it’s no secret that people’s lives have changed a lot since then, especially with the rise of highly processed foods – clues that show how diet, lifestyle, weight, environmental exposures, and the microbiome play a role. a role in certain combinations.
“Eight of the 14 cancers that were on the rise in our study were related to the digestive system,” explains Tomotaka Ugai, an epidemiologist at Harvard Medical School.
“The food we eat feeds the microbes in our gut, diet and directly affects the composition of the microbiome and ultimately these changes affect disease risk and outcomes.”
Other risk factors include sugary drinks, type 2 diabetes, obesity, a sedentary lifestyle, and alcohol consumption, all of which have increased significantly since the 1950s.
Interestingly, the team noted that while adults’ sleep duration hasn’t changed much over the past few decades, babies sleep far less than they did a few decades ago.
Of course, this study is far from conclusive, but rather a review of existing research. Therefore, the team cannot make changes here and measure the impact directly.
They also don’t have much data from low- and middle-income countries to continue studying, but suggest that “early-onset cancer incidence in these countries could become increasingly important, potentially contributing to a global early-onset cancer pandemic. “.
The team is now continuing their work and hopes to establish longitudinal cohort studies, which will involve the follow-up of young children for decades.
