#Psatest

Recent news of former US President Joseph Biden’s advanced prostate cancer has reignited global debate, including among Thai health professionals and men, about the value of prostate-specific antigen (PSA) blood tests for the early detection of prostate cancer. Prostate cancer, the most commonly diagnosed cancer among men in the United States and an important concern worldwide, presents a unique challenge: distinguishing aggressive, potentially deadly tumors from slow-growing ones that may never pose harm. This ongoing health debate holds particular significance for Thai men, as prostate cancer incidence in Thailand has gradually risen—mirroring trends in the West as life expectancy increases and populations age. Understanding the evolving research on PSA testing can help Thai families make informed decisions about their own health.

Prostate cancer is the most frequently diagnosed cancer among men in the United States and a growing concern worldwide. In Thailand, as life expectancy rises and the population ages, prostate cancer incidence is also increasing. The key question for Thai families: how should PSA screening fit into health decisions in midlife and beyond?

PSA tests measure a protein produced by the prostate in the blood. High PSA can signal cancer, but it can also trigger unnecessary biopsies and treatments for cancers that may never cause harm. Autopsy studies in the United States show that many older men harbor indolent cancers. This highlights a broader challenge: balancing early detection with avoiding overtreatment that can cause impotence, urinary incontinence, and bowel issues. Experts emphasize that PSA testing alone is not enough to establish a clear screening strategy.
