“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. These cancers include multiple myeloma, colorectal, endometrial, gallbladder, kidney and pancreatic.
Even though cancer most often strikes older adults, the sharpest increases were found in younger age groups. Pancreatic cancer exemplifies the pattern: Between 1995 and 2014, incidence of the disease rose by 0.77% annually among adults ages 45-49; by 2.47% among those ages 30-34; and by 4.34% among those ages 25-29. Kidney cancer had the sharpest annual increase for young Americans: 6.23% between 1995 and 2014.“
Some Cancers Are Rising in Millennials. Obesity Might Be Why
Findings
From 1995 to 2014 there were 14 672 409 incident cases for 30 types of cancer. Incidence significantly increased for six of 12 obesity-related cancers (multiple myeloma, colorectal, uterine corpus, gallbladder, kidney, and pancreatic cancer) in young adults (25–49 years) with steeper rises in successively younger generations. Annual increases ranged from 1·44% (95% CI −0·60 to 3·53) for multiple myeloma to 6·23% (5·32–7·14) for kidney cancer at age 25–29 years, and ranged from 0·37% (0·03–0·72) for uterine corpus cancer to 2·95% (2·74–3·16) for kidney cancer at age 45–49 years. Compared with people born around 1950, IRRs for those born around 1985 ranged from 1·59 (95% CI 1·14–2·21) for multiple myeloma to 4·91 (4·27–5·65) for kidney cancer. Conversely, incidence in young adults increased in successively younger generations for only two cancers (gastric non-cardia cancer and leukaemia), and decreased for eight of the 18 additional cancers, including smoking and HIV infection-associated cancers.
Interpretation
The risk of developing an obesity-related cancer seems to be increasing in a stepwise manner in successively younger birth cohorts in the USA. Further studies are needed to elucidate exposures responsible for these emerging trends, including excess bodyweight and other risk factors.
