A new study of American Cancer Society revealed that young adults were experiencing increasing rates of cancers badociated with obesity in the United States.
The research published today in The Lancet Public Health shows that millennia are now twice as likely to contract certain types of cancer as the generations that preceded them and that the risk of developing these cancers seems to increase with each new generation.
The new study examined two decades of incidence data collected from 1995 to 2014 for 30 cancer types in 25 states, collectively covering two-thirds of the US population. They found that for half of the types of cancer known to be linked to obesity, including colorectal, renal and pancreatic cancers, the incidence was increasing among young adults at an alarming rate, the younger generations continuing to see more cases than the previous generation.
Comparing these data to other types of cancer whose link to obesity is not currently known, the risk of young adults being affected remains stable or decreases in 16 of the 18 types of cancer over the course of time. l & # 39; study.
"Although the absolute risk of these cancers is low among young adults, these findings have important implications for public health," Ahmedin Jemal, Ph.D., Scientific Vice President of Surveillance & amp; Health Services Research at the American Cancer Society and lead author of the paper.
More worrisome perhaps, researchers believe that this increase in certain types of cancers in young adults may indicate future problems when these generations will become older adults.
"Cancer trends in young adults often serve as a wake-up call for the future burden of disease in older adults, where cancer occurs most often," says Jemal.
National Cancer Institute lists 13 defined types of cancer where obesity increases the risk of being touched, even if it is likely that others will be added to the list in the future. It is not currently known how obesity increases the risk of developing a type of cancer, but there is several theories.
First, obesity is often badociated with higher levels of inflammation, a risk factor for certain types of cancer. Another is that fat cells produce hormones such as estrogen, which can alter the normal functioning of & nbsp; certain types of cells develop, increasing the risk of cancers such as bad, endometrial and ovarian cancers.
"Given the strong increase in the prevalence of overweight and obesity among youth and the increasing risk of obesity-related cancers in current birth cohorts, the future burden of these cancers could worsen as age cohorts age, potentially interrupting or reversing the progress made in reducing cancer mortality in recent decades, "says Jemal.
