No: Testicular cancers, particularly mixed malignant germ cell tumors, of which choriocarcinoma falls into, are not generally inherited but occur sporadically.

Somatic mutations: This would be a great time for you to brush up on basic tumor biology. All tumors (benign and malignant / cancer) result from mutations that take place after we're already multicellular organisms. At most, one of these is inherited ("cancer family" genes). I'm glad you have an inquiring mind. Best wishes.
