Following can cause endometrial cancer:: (A) Metropathia hemorrhagica, (B) Gynandroblastoma, (C) Dysgerminoma, (D) All of the above
Answer is A. Endometrial cancer is mainly caused by excessive estrogen

Metropathia hemorrhagica is the same as cystic glandular hyperplasia and is a causative factor for endometrial cancer. Ref Dutta Gynae 5th /ed p 184
Gynandroblastoma is a virilising tumor which secretes androgens (not estrogens) and so does not lead to endometrial cancer  Ref. Shaw 14th /ed p 34
Dysgerminoma is a neutral tumor which does not secrete either male or female sex hormones but secretes placental alkaline phosphates, LDH and BHCG and therefore does not lead to endometrial cancer. - Ref Shaw 14th /ed 3386
