Cancer cases soared 79% globally among young adults over past 3 decades: study
Global News
While cancer tends to be more common in older people, the evidence suggests that cases among the under 50s have been rising in many parts of the world since the 1990s.
A surge in global cancer cases for people under the age of 50 has raised urgent concerns about the shifting landscape of this disease among younger populations, according to new research.
The study, published Tuesday in the journal BMJ Oncology, found that in 2019 new cases of early-onset cancers (people aged 15 to 49 years) were 3.26 million, a 79.1-per cent increase from 1990.
While breast cancer made up the highest number of cases in this age group, the fastest-rising cancers since 1990 have been those of the windpipe (nasopharynx) and prostate, the study found.
The researchers found that new cancer cases cancer with the heaviest death toll for young adults were breast, windpipe, lung, bowel and stomach.
“Cancers historically perceived to be more common in older age groups are now being diagnosed in younger adults, including colorectal, breast, oesophageal, gastric and pancreatic cancers, among others,” said Dr. Ashleigh Hamilton, a clinical lecturer at the Centre for Public Health at Queen’s University Belfast, U.K., in an editorial piece on the study. She was not involved in the research.
“It is important to educate both the public and healthcare professionals regarding the possibility of certain cancers in younger adults to allow earlier diagnosis, which in turn improves outcomes.”
In order to find the results, the researchers of the study, based in China, used data from the Global Burden of Disease 2019 Study for 29 cancers in 204 countries and regions.
They then looked at new cancer cases, deaths, health consequences and risk factors for people aged 14 to 49 in order to estimate annual percentage changes between 1990 and 2019.
