The incidences of Bowel cancer is rising among young adults, according to studies conducted in Europe and high-income countries.

They show declines in the overall incidence among people aged 50 years or above.

One study, published in the journal Gut, analyses data from 143.7 million people aged 20-49 years from 20 European countries, of whom 0.13 per cent were diagnosed with colorectal cancer (CRC).

It points to an increase of 8 per cent in CRC incidence per year from 2004 to 2016 among people aged between 20 to 29 years, and 5 per cent increase in the age group of 30 to 39 years from 2005 to 2016.

The increase in the age group of 40 to 49 years was 1.6 per year from 2004 to 2016.

The study suggests to elucidate the cause of this trend and reconsider the screening guidelines.

A second study, published in the Lancet Gastroenterology and Hepatology journal, found an overall decline or stabilisation in the colon and rectal cancer incidents but underlined a significant increase in CRC incidences among younger adults in four countries, including the UK.

The rate increase in the incidences of colon cancer among UK’s younger adults was 1.8 per cent, while it was 1.4 per cent for rectal cancer.

It also calls for further studies to find the root cause and develop better prevention and early detection strategies.
