- 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结果在4-10之间,你该怎么办?25%的概率,做不做活检?如果做,四个人里有三个不是癌,另外一个确诊是癌,但大多数病情发展缓慢,可以不做过多的干预。
PSA结果小于4呢?有15%的癌症概率。(你是不是现在就开始焦虑了?)
