Low incidence and death of prostate cancer in the United States

A medical study showed that rates of death and death from prostate cancer were lower in many countries, while the United States allowed these countries to experience the largest decline in infection rates.

"Previous studies indicate significant variation in prostate cancer rates, due to factors such as detection practices, availability of treatment, and genetic factors," said Maribee Freeman, researcher at the American Society. for Cancer Research (AACR).

"By comparing infection rates in different countries, we can assess the differences between detection practices and treatment improvements," she said in a press release.

Researchers looked at short- and long-term data from 44 countries for which data were available on infection and 71 countries for data on prostate cancer deaths. Of the 44 countries evaluated, prostate cancer rates increased in four countries and decreased in seven countries, United States. Rates remained stable in 33 other countries, of the 71 countries evaluated for prostate cancer mortality, there were decreases in 14 countries, increases in three countries and no change in 54 countries.

In 2012, prostate cancer was the most common type of cancer in men in 96 countries and the leading cause of death in 51 countries, according to the study.

Freeman said the results confirm the benefits of screening for prostate-specific antigen: in the United States, infection rates increased between the 1980s and the early 1990s, and then dropped between the middle of 2000 and 2015, mainly due to increased use of PSA.

This type of screening is less available in poor countries, which means that men are more likely to be diagnosed in the late stages of prostate cancer and more likely to die, noting that some countries are considering reducing the recommendations. in PSA testing because of fears of overtreatment of prostate cancer. The symptoms will never be the cause.
