Testicular cancer originates in the testicles, the male reproductive glands that produce sperm and testosterone. It is the most common cancer in young men (ages 15–35) and is highly curable.
Main types:
• Seminoma – slow-growing, radiosensitive
• Non-seminoma – includes embryonal carcinoma, yolk sac tumor, choriocarcinoma, teratoma; tends to grow faster
