Malignant disease conditions 

Ovarian cancer is a malignant neoplasm arising from the ovary and is one of the most lethal gynecological cancers. Epithelial tumors account for approximately 90% of all ovarian malignancies. Due to the deep anatomical location of the ovaries and the absence of specific early symptoms, most patients present with advanced disease.

Choriocarcinoma is a highly malignant form of gestational trophoblastic neoplasia characterized by aggressive trophoblastic proliferation and early hematogenous spread. It may occur following a hydatidiform mole, spontaneous abortion, ectopic pregnancy, or term pregnancy.

Hydatidiform mole is a form of gestational trophoblastic disease characterized by abnormal proliferation of trophoblastic tissue and swelling of chorionic villi. It results from abnormal fertilization and is classified into two main types: complete hydatidiform mole and partial hydatidiform mole.

Cancer of the uterine cervix is a malignant disease arising from the cervical epithelium and is strongly associated with persistent infection by high-risk types of human papillomavirus (HPV). It is one of the most common cancers affecting women, particularly in low- and middle-income countries.

Endometrial cancer is a malignant neoplasm arising from the endometrial lining of the uterus and is one of the most common gynecological malignancies in women. It predominantly affects postmenopausal women, although it may occur in younger women with specific risk factors.
