"Why Routine Screening Is Discouraged After 70Slow-Growing Tumors:
Most prostate cancers diagnosed in older men are indolent, meaning they grow very
slowly. Competing Causes of Death: Statistically, a 70-year-old man is far more likely to
die of other natural causes (like heart disease or stroke) before a slow-growing prostate
tumor ever causes symptoms or shortens his life. Experts note most older men die with
prostate cancer rather than from it.
High Risk of Overdiagnosis: Routine testing frequently uncovers low-risk, non-lethal
tumors that never would have caused health problems if left undetected.
Harms of Overtreatment: When a PSA test comes back high, it often triggers a cascade
of invasive medical interventions. Treatments like surgery or radiation carry heavy risks
for older men, including permanent urinary incontinence, erectile dysfunction, and bowel
problems."
