Cancer: Under-50s cancer cases surge 79% in 30 years; here's what causing it

A new study published in BMJ Oncology found that the number of cancer cases among the under-50s around the world appears to have risen sharply in the past 30 years. In 2019, there had been 3.26 million cases - 79% more than in 1990. Here is everything you need to know about what is causing this spike in cancer cases among people below 50.

According to the researchers, lifestyle factors like excess weight, diets high in red meat and salt as well as physical inactivity could be behind the rise in cancer cases among 14- to 49-year-olds. Genetic factors could also be playing a role. The researchers added that more work was needed for a "full understanding" of the rise in cases. Still, it is important to improve detection and prevention of cancer in younger adults.

According to the findings of the study, the regions with the highest rates of early-onset disease were North America, Australasia and Western Europe. More research is needed to determine the exact cause.

When it comes to death rate, cancers of the digestive system, skin and breast were the most common. According to the data, cancer killed more than a million under-50s, a rise of over 25%. It is important to note that 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.

Experts have cautioned against reading too much into the findings. The research did not take into account a 40% rise in the total population. The team of experts from around the world, including the US, China and the UK, agreed no firm conclusions could be drawn.

The study does shed light on being aware of your lifestyle choices. If you are worried about cancer risk, there are lots of ways to reduce this. Some healthy habits include not smoking, a balanced diet, getting plenty of exercise and staying safe in the sun. If you feel unwell or notice any suspicious symptoms, it is important to consult your doctor for a proper diagnosis.
