Washington, 7 Sep (PTI): The incidence of cancers diagnosed before the age of 50 has dramatically increased around the world, with this rise beginning around 1990, according to a study.<\/p>\n
These early onset cancers include cancers of the breast, colon, esophagus, kidney, liver, and pancreas among others, the researchers said.<\/p>\n
Possible risk factors for early-onset cancer include alcohol consumption, sleep deprivation, smoking, obesity, and eating highly processed foods, the researchers said.<\/p>\n
While adult sleep duration has not drastically changed over the several decades, children are getting far less sleep today than they were decades ago, they said.<\/p>\n
Risk factors such as highly-processed foods, sugary beverages, obesity, type 2 diabetes, sedentary lifestyle, and alcohol consumption have all significantly increased since the 1950s, which researchers speculate has accompanied altered microbiome.<\/p>\n
“From our data, we observed something called the birth cohort effect,” said Shuji Ogino, a professor at the Brigham and Women’s Hospital, US.<\/p>\n
“This effect shows that each successive group of people born at a later time (e.g., decade-later) have a higher risk of developing cancer later in life, likely due to risk factors they were exposed to at a young age,” Ogino said.<\/p>\n
The study, published recently in the journal Nature Reviews Clinical Oncology, found that the risk is increasing with each generation.<\/p>\n
For instance, people born in 1960 experienced higher cancer risk before they turn 50 than people born in 1950.<\/p>\n
The researchers predict that this risk level will continue to climb in successive generations.<\/p>\n
They first analysed global data describing the incidence of 14 different cancer types that showed increased incidence in adults before age 50 from 2000 to 2012.<\/p>\n
The team then searched for available studies that examined trends of possible risk factors including early life exposures in the general populations.<\/p>\n
The researchers found that the early life exposome, which encompasses one’s diet, lifestyle, weight, environmental exposures, and microbiome, has changed substantially in the last several decades.<\/p>\n
They hypothesised that factors like the westernised diet and lifestyle may be contributing to the early-onset cancer epidemic.<\/p>\n
The team acknowledged that this increased incidence of certain cancer types is, in part, due to early detection through cancer screening programs.<\/p>\n
The researchers couldn’t precisely measure what proportion of this growing prevalence could solely be attributed to screening and early detection.<\/p>\n
However, they noted that increased incidence of many of the 14 cancer types is unlikely solely due to enhanced screening alone. (PTI)<\/p>\n","protected":false},"excerpt":{"rendered":"
