Caution over study suggesting under-50 cancer surge

Mar 21,2023 2:10 pm

The Number of cancer cases among the under-50s around The World appears to have risen sharply in The Past 30 years, a study suggests.

Research published in BMJ Oncology found there had been 3. 26 million cases in 2019 - 79% More Than in 1990.

But experts cautioned against reading too much into the findings.

The research did not take into account a 40% rise in the total population, while factors such as better reporting may also have played a role.

The Team , of experts from around The World , including the US, China and the UK, agreed no firm conclusions could be drawn.

But they were concerned lifestyle factors - including excess weight, diets high in Red Meat and salt and physical inactivity - could be pushing cancer cases up among 14- to 49-year-olds.

Genetic factors could also be playing a role, they added.

Death rate

Cancers of the Digestive System , skin and breast were The Most common.

Cancer killed More Than A Million under-50s in 2019, a rise of over 25% - But with the 40% population rise, this could actually indicate a falling death rate.

The data was taken from the Global Burden of Disease dataset, which covers More Than 200 countries.

The researchers said more work was needed for a " full understanding" of The Rise in cases But it suggested efforts were needed to improve detection and prevention in younger adults.

Prof Dorothy Bennett, a cell-biology expert at the University of London, agreed it was " not possible" to draw detailed conclusions.

Cancer Research UK said there was some evidence of rising cancer rates among 18- to 49-year-olds in the UK.

But Dr Claire Knight , of CRUK, added: " However alarming this might seem, cancer is primarily a disease of older age, with the majority of new cancer cases worldwide being diagnosed in those aged 50 and above. "
