The number of under-50s being diagnosed with bowel cancer is increasing worldwide, according to research that also reveals rates are rising faster in England than almost any other country. For the first time, global data suggests doctors are seeing more young adults develop early-onset bowel cancer, from Europe and North America to Asia and Oceania. An increase in rates was reported in 27 of the 50 countries examined, with the greatest annual increases seen in New Zealand (4%), Chile (4%), Puerto Rico (3.8%), and England (3.6%). Experts are still in the early stages of understanding the reasons behind the rise.
