  schema:description "Spermatocytic tumour, once called spermatocytic seminoma, is a rare testicular germ cell tumour of older men that arises from maturing sperm precursors rather than from the fetal germ cells behind ordinary testicular cancer. It almost never spreads, so removing the testis is the whole treatment and no chemotherapy or radiotherapy is needed."@en ;
