Study: Millennials face greater risk of some cancers due to obesity

Six of the 12 obesity-related cancers — colorectal, uterine corpus (endometrial), gallbladder, kidney, multiple myeloma, and pancreatic — showed increased incidences in young adults and in successively younger birth groups in a stepwise manner.

The risk of colorectal, uterine corpus, pancreatic and gall bladder cancers in millennials is about double the rate baby boomers had at the same age, per the report.

But, for almost all (16 out of 18) of the non-obesity related cancers (exception was gastric non-cardia cancer and leukaemia), cancers dropped or stabilized in successively younger generations — meaning the absolute risk of all cancers is lower for the youngest age groups. This included cancers related to HIV infections or smoking.
