What are the types of testicular cancer? What are the types of testicular cancer?

Testicular cancer is divided into primary testicular cancer and secondary testicular cancer according to the cause of the disease. According to the degree of cell differentiation, germ cell tumors can be divided into two categories: seminoma and non-seminoma. Non-germ cell tumors include interstitial cell tumors, supporting cell tumors, gonadal stromal tumors and mixed tumors.

1. Classification by Cause

The cause of primary testicular cancer is unclear. It may be caused by poor living and eating habits, orchitis or immune deficiency. Secondary testicular cancer is usually caused by other diseases. The vast majority of testicular cancers are primary, and secondary testicular cancer is relatively rare. Primary testicular cancer is divided into germ cell tumors and non-germ cell tumors.

2. Classification by degree of cell differentiation

Germ cell tumors can be divided into two categories: seminomas and non-seminomas. The latter include embryonal carcinoma, teratoma, teratocarcinoma, yolk sac tumor, and choriocarcinoma. Non-germ cell tumors include Leydig cell tumors, Sertoli cell tumors, gonadal stromal tumors, and mixed tumors.
