The prostate cancer test has turned into a costly public health disaster, according to a discoverer on Wednesday. The PSA screening cost more than $3 billion in a year.

"The test's popularity has led to a hugely expensive public health disaster”, said Dr. Richard Ablin of the University of Arizona.

Prostate cancer is the second leading widespread cancer in men globally after lung cancer, which kills around 254,000 men per year.

Doctors have regularly suggested PSA screening to men aged 50 with the belief that early treatment can cure prostate cancer.

Prostate cancer treatments can often end up causing incontinent and sexual dysfunction in around a third of patients. Many men also face inflammatory bowel diseases.

Ablin revealed that the medical community is gradually decreasing the use of PSA screening. Ablin forced the medical community "confront reality and stop the inappropriate use of PSA screening”.
