Embryonal carcinoma is a type of cancer that primarily affects young men, often occurring in the testicles. It is classified as a germ cell tumor, which means it originates from the cells that develop into sperm. This cancer can grow quickly and may spread to other parts of the body if not treated promptly. Treatment for embryonal carcinoma typically involves surgery to remove the tumor, followed by chemotherapy or radiation therapy to eliminate any remaining cancer cells. Early detection is crucial for improving outcomes, and regular self-examinations can help identify any unusual changes in the testicles.
