According to a new study, cancer incidence and mortality rates are projected to increase rapidly in men by 2050. Researchers said that the greatest impact of this increase will be seen in men aged 65 years and above.

Globally, cancer is the second leading cause of death after heart disease. However, a new study predicts it will become the leading cause of death by the end of this century.

Cancer not only puts a strain on health care systems, but also has a huge economic burden, with an estimated cumulative cost of $25.2 trillion between 2020 and 2050.

The new study, published in the journal Cancer, was carried out by Australian researchers who analysed 2022 data covering 185 types of cancer in 30 countries and territories to forecast future trends.

The study estimates that cancer cases in men will rise from 10.3 million in 2022 to 19 million by 2050, an increase of 84%.

Cancer deaths are expected to nearly double, from 5.4 million in 2022 to 10.5 million in 2050, an increase of 93%.

The estimated increase in cancer deaths for men aged 65 and older is even greater, 117%.

The study also found that countries with low income levels and shorter life expectancy are likely to see the greatest increase in cancer deaths among men.

In particular, cancer cases and deaths in Africa and the Eastern Mediterranean are projected to increase 2.5-fold between 2022 and 2050. In contrast, Europe is expected to have a more modest increase of around 50%.

Men currently have a greater risk of dying from cancer than women, mainly due to smoking, alcohol consumption, and exposure to carcinogens in the workplace.

Another reason for this is that men are less likely to participate in cancer screening programs.

Lung cancer, which was the leading cause of cancer and cancer deaths in men in 2022, is expected to remain the biggest threat in 2050.

The cancers with the highest projected increases in men include cases of mesothelioma (tumors of the tissues lining the lungs, abdomen, heart and other organs) and deaths from prostate cancer.

The researchers highlighted the need for stronger healthcare systems to reduce this rising burden.

“Strengthening health infrastructure, enhancing workforce quality and access, promoting national and international collaboration, and promoting universal health coverage are critical to reduce cancer disparities and ensure cancer equity among men globally,” the researchers wrote.
