老帖在此：
经版友推荐， 上星期到这里的一个大学泌尿科教授/ 专家那里咨询3rd opinion. 他同意上一位专科医生的说法， 认为目前not valuable for biopsy， 同时又进一步给出了这些理由：
1. Your have numerous times PSA free pretty high. That means risk is very, very low,
2. Although your PSA is high, your PSA density is low, less than 0.1. Say if normal prostate volume is 30 and PSA value 4.0, then, the normal PSA density should be 0.1333.
3. Suggest to do a 4K score and exosome test, if both are normal, then you are just like a regular people. If abnormal, then, do MRI.
4. Take both Proscar and Tamsulosin for 6 months, then, do PSA, PSA Free and TRUS again. Your PSA should drop about in half. Your prostate volume should be shrink about 1/3.
现在2比1了， 应该没事了吧？ 头疼的是找不到地方去做4K score and exosome test， 还要自掏腰包.
各位怎么看呢？谢啦！
