Obesity-linked cancer risk rises in young

Obesity-linked cancer risk rises in young

Researchers from the American Cancer Society studied cancer data covering half of the U.S. population between 1995 and 2014.

Even though cancer most often strikes older adults, the sharpest increases were found in younger age groups. In 2016, the International Agency for Research on Cancer (a branch of the World Health Organization) published a report linking obesity to a higher risk of 12 cancers: Colorectal, esophageal, gallbladder, gastric cardia (a type of stomach cancer), kidney, liver and bile duct, multiple myeloma (a type of bone marrow cancer), pancreatic and thyroid cancer; and, in women, endometrial, breast and ovarian cancer.

The study found there were steep rises in the number of people in younger generations suffering from the cancers.

Young adults in the US are experiencing higher rates of obesity-related cancers than their predecessors did at their age, a new American Cancer Society study finds.

But the researchers conclude that their findings have significant public health implications, particularly for health care providers and policy makers, and provide a stepping stone for future research on the relationship between the present obesity epidemic and early onset cancer.

Pancreatic cancer cases rose by 4.34 per cent a year among 25 to 29-year-olds over the last two decades.


The age category that experienced the greatest increase in frequency for four of the other five cancers was also those between 25 to 29.

The obesity epidemic may be contributing to an increase in certain cancers among millennials in the USA, a new study suggests.

Obese people will not definitely develop cancer but they are at a higher risk than people who are a healthy weight.

Rates of cancers caused by obesity are rising fastest in the young, American scientists say. Rates of some of these same cancers also increased among older adults, but the increases were much smaller, the researchers said. By 2014, obesity accounted for 60% of endometrial cancers, 36% of gallbladder cancers, 33% of kidney cancers, 17% of pancreatic cancers and 11% of multiple myeloma among adults ages 30 and older, the new paper says.

Dr Jemal said: 'Over the past few decades, death rates have been in decline for most cancers, but in the future obesity could reverse that progress, barring any interventions.

Researchers analyzed 20 years of incidence data for 30 cancers - 12 of which are associated with obesity and excess body weight - among adults ages 25 to 84 in 25 states from the North American Association of Central Cancer Registries' Cancer in North America database.
