Millennials Getting More Obesity-Related Cancers, Study Finds

Obesity-linked cancers on the rise in young adults 'Shocking' rise in obesity-related cancers among young adults

Meanwhile a separate study by Erasmus University Rotterdam into bowel cancer past year found soaring rates in younger people across Europe - with scientists saying rising obestity levels were most likely to be the reason for the jump.

These included multiple myeloma, colorectal, uterine corpus, gallbladder, kidney and pancreatic cancers.

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).

During the period examined, the incidence of pancreatic cancer, for example, increased by about one percent per year for adults aged 45 to 49.

The American Cancer Society believes this shift could impede the progress recently made in battling cancer.

Professor Sanchia Aranda, CEO Cancer Council Australia said, "With more than two thirds of adults considered overweight or obese, and almost half insufficiently active, these results show we have the potential to prevent a significant number of cancers in Australia and potentially save thousands of lives".

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

"The risk of developing an obesity-related cancer seems to be increasing in a stepwise manner in successively younger birth cohorts in the U.S.", writes the team.

But certain cancers are becoming more common among younger Americans, and researchers think obesity may be to blame, finds a new report from the American Cancer Society and the National Cancer Institute.

Fowler overcomes odd triple bogey for Phoenix crown
PGA Tour rules official Slugger White determined Fowler's ball was in play after the drop, so he was assessed a one-shot penalty. Johnson, the American star ranked No. 3 in the world, birdied the final two holes at Royal Greens to reach 19-under 261.

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

"Cancer trends in young adults often serve as a sentinel for the future disease burden in older adults, among whom most cancer occurs", Jemal said. They cite figures which show that the prevalence of obesity or being overweight increased by more than 100 percent (from 14.7 percent to 33.4 percent) between 1980 and 2014 among USA children and adolescents.

"Although the absolute risk of these cancers is small in younger adults, these findings have important public health implications", said Ahmedin Jemal, DVM Ph.D., scientific vice president of surveillance & health services research and senior/corresponding author of the paper.

Rates of six different cancers that are associated with obesity increased among adults ages 25-49 between 1995 and 2014, according to the research, which was published in the journal Lancet Public Health and based on information in the Cancer in North America database.

The link between obesity and cancer is of growing concern.

UN's International Agency for Research on Cancer (IARC) did not show similar increases.

The labels have been added to this press release as part of a project run by the Academy of Medical Sciences seeking to improve the communication of evidence. They looked at 30 types of cancers, including 12 that are considered obesity-related. For incidence rate ratios please see Tables S5 (12 obesity-related cancers) and S6 (18 additional cancers) in the appendix.
