前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)大(da)不一定(ding)是(shi)(shi)前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)增(zeng)(zeng)生(sheng)。前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)增(zeng)(zeng)生(sheng)是(shi)(shi)一個病理學名詞，以前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)間質及(ji)上(shang)皮細(xi)胞增(zeng)(zeng)生(sheng)為其特(te)征。組織學的(de)前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)增(zeng)(zeng)生(sheng)可以只表現(xian)為顯微鏡下(xia)的(de)增(zeng)(zeng)生(sheng)而不導致(zhi)前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)體(ti)(ti)積(ji)的(de)改變。某些前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)的(de)其他疾病，例如急性細(xi)菌性前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)炎(yan)，因前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)管(guan)及(ji)其周(zhou)圍間質組織充血、水(shui)腫(zhong)，前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)小(xiao)管(guan)和腺(xian)(xian)(xian)泡膨脹，臨床(chuang)上(shang)直腸(chang)指診或B超檢查可發(fa)現(xian)前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)腫(zhong)脹增(zeng)(zeng)大(da)，但這(zhe)種前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)體(ti)(ti)積(ji)的(de)增(zeng)(zeng)大(da)并(bing)非是(shi)(shi)前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)間質及(ji)上(shang)皮細(xi)胞增(zeng)(zeng)生(sheng)導致(zhi)，所以不是(shi)(shi)前(qian)(qian)(qian)(qian)列腺(xian)(xian)(xian)增(zeng)(zeng)生(sheng)。

另外(wai)，因為(wei)個體(ti)差異的(de)原(yuan)因，就如每個人高矮、胖瘦(shou)不同一樣(yang)，男性前(qian)(qian)列(lie)(lie)(lie)腺的(de)大小也(ye)存(cun)在(zai)差異。不能機械地(di)(di)看待前(qian)(qian)列(lie)(lie)(lie)腺的(de)大小，一定要(yao)結(jie)合年齡、是否(fou)對身體(ti)造成影(ying)響，是否(fou)存(cun)在(zai)其他疾病等多(duo)方面因素綜合地(di)(di)對待前(qian)(qian)列(lie)(lie)(lie)腺大小的(de)問題，不能簡單(dan)地(di)(di)認為(wei)前(qian)(qian)列(lie)(lie)(lie)腺體(ti)積大就是前(qian)(qian)列(lie)(lie)(lie)腺增生。

有些(xie)中青年(nian)(nian)男(nan)性體(ti)檢時B超檢查發現前列(lie)腺(xian)體(ti)積(ji)較大，就認為是前列(lie)腺(xian)增生，很是緊張(zhang)，這是一個典型的(de)誤區(qu)，對于中青年(nian)(nian)男(nan)性，前列(lie)腺(xian)體(ti)積(ji)大小沒有意義。
