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%.
实际上区别没有那么大，不过是早几年焦虑自己得了癌症而已。
前列腺癌症做不做手术5年生存率都在90%以上，主要是看术后个人感觉如何，有些人排尿有改善，有些人反而更差，都是有一定概率的。有些人不是筛查发现了前列腺肿瘤，根本就不知道自己得了这个病，因为没有任何症状，所以是否手术需要根据自己的情况来决定。

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？）
