Just Saw The Oncologist - TESTICULAR CANCER
9Testicular cancer happens when cells in the testicle grow to form a tumor. This is rare. More than 90 percent of testicular cancers begin in the germ cells, which produce sperm. There are two types of germ cell cancers (GCTs). Seminoma can grow slowly and respond very well to radiation and chemotherapy. Non-seminoma can grow more quickly and can be less responsive to those treatments. There are a few types of non-seminomas: choriocarcinoma, embryonal carcinoma, teratoma and yolk sac tumors.
There are also rare testicular cancers that don’t form in the germ cells. Leydig cell tumors form from the Leydig cells that produce testosterone. Sertoli cell tumors arise from the Sertoli cells that support normal sperm growth. Testicular tumors can be made of more than one type of cell.
