PSA檢查的虛警率太高

Here's a breakdown of PSA levels and their potential implications:

• PSA below 4 ng/mL: Approximately 15% of men with this PSA level will have prostate cancer if a biopsy is performed, according to the American Cancer Society. 
   
• PSA between 4 and 10 ng/mL (borderline range): About 25% of men in this range have prostate cancer. 
   
• PSA above 10 ng/mL: The probability of prostate cancer is greater than 50%. 

 

如果PSA結果在4-10之間，你該怎麽辦？25%的概率，做不做活檢？如果做，四個人裏有三個不是癌，另外一個確診是癌，但大多數病情發展緩慢，可以不做過多的幹預。

 

PSA結果小於4呢？有15%的癌症概率。（你是不是現在就開始焦慮了？）
