Study: Significant increase in prostate cancer rates expected

According to a study published in the Lancet, prostate cancer rates are expected to increase significantly in the coming years in various parts of the world, particularly in less affluent countries.

The authors of the study, published today, concluded that based on the expansion of currently recorded population changes, “the annual number of new cases, which reached 1.4 million in 2020, will double to 2.9 million in 2040.”

The researchers attributed the rise to “increasing life expectancy and changes in age pyramids.”

Prostate cancer is the most common type of cancer in men, accounting for 15 percent of all cases, and most cases occur in men over the age of fifty. The frequency of cases gradually increases in the age group above this limit.

As many poor or developing countries are in the process of partially closing the life expectancy gap compared to their developed counterparts, the number of prostate cancer cases is expected to increase automatically.

The researchers added: “Unlike other major problems such as lung cancer or cardiovascular disease, it is not possible through public health policies to avoid an increase in these cases.”

In fact, prevention may not be as effective in reducing risk factors for prostate cancer, genetics, height, etc., as smoking cessation, for example, is for lung cancer. Only an association between prostate cancer and overweight has been proven, but it is unclear whether the relationship is causal.

However, the study authors believe that several measures can reduce the incidence of prostate cancer.

For example, they called for early diagnosis to be sought in less affluent countries, where prostate cancers are diagnosed too late to be effectively treated.

On the other hand, they warned of the risk of “overdiagnosis and overtreatment” in developed countries.
