Obesity-linked cancers on the rise in adults

A sharp increase in the rate of obesity-linked cancers among young adults in the United States could foreshadow a reversal in the overall decline in cancer mortality, researchers warned yesterday.

In a sweeping study covering two-thirds of the US population, they showed that half a dozen cancers for which obesity is a known risk factor became more frequent from 1995 to 2015 among women and men under 50.

The younger the age bracket, the more quickly these cancers gained ground, they reported in The Lancet, a medical journal.

During the period examined, the incidence of pancreatic cancer, for example, increased by about one percent per year for adults aged 45 to 49. Among 30 to 34-year-olds, the average annual percent increase was more than twice that high.

And among 25 to 29-year-olds, the rate jumped by 4.4 percent per year.

Comparing five-year age brackets from 25 to 80, the annual hike was similarly highest among the 25 to 29 cohort for four other obesity-linked cancers: kidney (6.23 percent), gallbladder (3.71 percent), uterine (3.35 percent), and colon (2.41 percent).

"Our findings expose a recent change that could serve as a warning of an increased burden of obesity-related cancers to come in older adults," said co-author Ahmedin Jemal of the American Cancer Society, USA.
