The number of cancer cases is increasing worldwide. In 2022, 20 million new cancer diagnoses will be made. That number is forecast to increase by 77 percent to 35 million diagnoses per year by 2050, the International Agency for Research on Cancer (IARC) reported on Thursday.
One in five people will develop cancer during their lifetime. One in nine men and one in twelve women die from it.
Causes of the expected increase include population growth and the fact that people are living longer, according to the IARC. In addition, there are increased risks due to lifestyle changes. Tobacco, alcohol and obesity play a role in this, as does air pollution.
The agency, based in the French city of Lyon, belongs to the World Health Organization (WHO) in Geneva, Switzerland. Two years earlier, in 2020, 19.3 million cancer diagnoses had been made, according to an earlier statement from the IARC. The comparison must take into account that the data collection methods have improved in the meantime.

Breast cancer is the most common in women, followed by lung and colon cancer. In men, lung cancer is the most common type, followed by prostate and colon cancer. The agency looked at data from 185 countries.
WHO Regional Director for Europe, Hans Kluge, said that in the European Region, which includes 53 countries in Europe and Central Asia, cancer deaths will increase by 38 percent by 2045, according to the IARC.
