- 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?)
