Researches at the Baylor College of Medicine identified and defined three types of invasion of prostatic cancer into seminal vesicles.
|Type I||direct spread of prostate cancer along the ejaculatory duct complex into the seminal vesicles|
|Type II||invasion through the prostatic capsule into the seminal vesicles
|Type III||prostate cancer metastases in the seminal vesicles with no direct connection to the primary focus|
