Prostate cancer diagnoses, deaths decreasing worldwide, study says



Researchers looked at the World Health Organization data from five continents from 1980 to 2012 and saw an encouraging trend. In most parts of the world, the rate of men diagnosed with and dying of prostate cancer decreased or stabilized, according to the study, presented Tuesday at the American Association of Cancer Research Meeting in Atlanta.

A walnut-shaped gland under the bladder, the prostate secretes seminal fluid, which provides nutrition for and allows the transport of sperm.

Dr. Alex Krist, vice president of the US Preventive Services Task Force and professor of family medicine and population health at Virginia Commonwealth University, who was not involved in the study, explained that prostate cancer is one of the most common cancers that affects men. , prostate cancer grows slowly. "

The survival rate of patients with prostate cancer depends on factors such as how far it has spread.

The new study notes that prostate cancer is the second leading cause of cancer diagnosis and the sixth most common cause of cancer death among men worldwide. The authors also note that, since 201

2, prostate cancer has led to a male cancer incidence or new diagnosis in 96 countries, and is the most common cause of death among men in 51 countries.

 More men with low-risk prostate cancer are forgoing treatment, study finds

"By comparing rates from different countries, "MaryBeth Freeman, lead study author and senior associate research scientist at the American Cancer Society, said in a statement. "Previous studies have shown significant variation in prostate cancer rates, due to factors including detection practices, availability of treatment, and genetic factors."

Prostate cancer diagnosis rates decreased in seven countries from 2008 to 2012, and 33 countries showed a stabilization in diagnosis rates, the study found. From 2008 to 2012, the United States had the largest decrease in the number of men diagnosed with prostate cancer.

Freeman and her colleagues found these results encouraging and believe that research supports the use of prostate-specific antigen screening

This test was approved by the US Food and Drug Administration in 1986 to monitor prostate cancer, and Freeman says its increased use has resulted in a decline in the diagnosis from the 2000s to 2015. In countries with low prevalence, screening is less available, later diagnoses and increased mortality rates are more common, she noted. cancer from 2008 to 2012 were Brazil, Lithuania, and Australia. The highest mortality rates from prostate cancer include Caribbean countries such as Barbados, Trinidad and Tobago, Cuba and South Africa, Lithuania, Estonia and Latvia. ” data-src-mini=”//cdn.cnn.com/cnnnext/dam/assets/170411112431-prostate-exam-stock-small-169.jpg” data-src-xsmall=”//cdn.cnn.com/cnnnext/dam/assets/170411112431-prostate-exam-stock-medium-plus-169.jpg” data-src-small=”http://cdn.cnn.com/cnnnext/dam/assets/170411112431-prostate-exam-stock-large-169.jpg” data-src-medium=”//cdn.cnn.com/cnnnext/dam/assets/170411112431-prostate-exam-stock-exlarge-169.jpg” data-src-large=”//cdn.cnn.com/cnnnext/dam/assets/170411112431-prostate-exam-stock-super-169.jpg” data-src-full16x9=”//cdn.cnn.com/cnnnext/dam/assets/170411112431-prostate-exam-stock-full-169.jpg” data-src-mini1x1=”//cdn.cnn.com/cnnnext/dam/assets/170411112431-prostate-exam-stock-small-11.jpg” data-demand-load=”not-loaded” data-eq-pts=”mini: 0, xsmall: 221, small: 308, medium: 461, large: 781″ src=”data:image/gif;base64,R0lGODlhEAAJAJEAAAAAAP///////wAAACH5BAEAAAIALAAAAAAQAAkAAAIKlI+py+0Po5yUFQA7″/>
