This statement is false. Primary carcinoma of the seminal vesicles is exceedingly rare. The seminal vesicles are much more commonly involved secondarily by direct extension from advanced prostate cancer or, less commonly, from bladder or rectal cancer. Prostate cancer is one of the most common cancers in men worldwide. Therefore, finding a tumor mass in the region of the seminal vesicles is far more likely to represent spread from a prostate primary than a primary seminal vesicle carcinoma. Primary seminal vesicle cancer is so uncommon that its diagnosis requires strict pathological criteria to exclude invasion from a neighboring organ.
