The researchers responsible for the study say that the expected increase in the number of prostate cancer cases is linked to an increase in life expectancy and changes in the age pyramid around the world.

As published Lanceta peer-reviewed medical scientific journal, the number of new cases of prostate cancer worldwide will double over the next two decades as poor countries catch up with the aging of rich countries.

Our findings suggest that the number of new annual cases will rise from 1.4 million in 2020 to 2.9 million in 2040.

It was read in the Lancet, based on a study on demographic changes, according to Science Alert.
The researchers responsible for the study point out that the increase in the number of cases is linked to an increase in life expectancy and changes in the age pyramid around the world.
Prostate cancer is the most common type of cancer in men, accounting for about 15% of cases.  It appears mainly after the age of 50 and becomes more common as men age.  Therefore, the researchers explain that as life expectancy improves in developing countries, the number of prostate cancer cases also increases.

Unlike what happens with cancers such as lung cancer or heart disease, public health policies cannot change this.  Moreover, genetic factors are much less controllable than, for example, smoking causing lung cancer.
Although there is a relationship between weight and weight, it is not yet known whether this is a direct cause of prostate cancer.
The researchers also said health authorities should encourage early screening in developing countries, where the disease is often diagnosed too late to allow effective treatment.
