In just three decades, the number of people under 50 with cancer has increased by 80%

This is the first study to look at the issue and its risk factors for young people on a global scale. In this work, researchers analyzed data from 204 countries on 29 types of cancer, The Guardian reported.

Experts looked at new cases, deaths, health effects and contributing factors for people aged 14 to 49, to estimate changes from 1990 to 2019.

According to the report, cases of early-onset cancer worldwide increased from 1.82 million in 1990 to 3.26 million in 2019. Meanwhile, cancer deaths among adults aged 40, 30 and younger increased by 27%. The study found that more than 1 million people under 50 die from the disease each year.

During the period 1990-2019, breast cancer accounted for the largest number of cases and deaths, at 13.7 and 3.5 per 100,000 of the global population, respectively. Meanwhile, cases of early-onset tracheal and prostate cancers increased the fastest over the same period, with estimated rates of 2.28% and 2.23% per year, respectively.

The encouraging sign is that early-onset liver cancer cases have decreased by about 2.88% per year.

The highest rates of early-onset cancer in 2019 were in North America, Oceania and Western Europe. Low- and middle-income countries in Oceania, Eastern Europe and Central Asia were also affected. In these regions, early-onset cancer has a greater impact on women than men due to poorer health.

Based on observed trends, the researchers estimate that global early-onset cancer cases and deaths will increase by 31% and 21%, respectively, by 2030, with people in their 40s at highest risk.

Experts are still investigating the reasons behind the rise in cases. Poor diet, alcohol and tobacco use, physical inactivity and obesity may be among the factors, the study authors said in a paper published in BMJ Oncology .

“Encouraging a healthy lifestyle, including a healthy diet, limited tobacco and alcohol consumption, and appropriate outdoor activity, can reduce the risk of early-onset cancer, the report said.

The Times of India quoted Dr. Devi Shetty, Chairman of Narayana Health Hospital (India), who was not involved in the study, also noting that environmental factors such as pollution, dietary habits and reduced physical activity cannot be overlooked.
