Ovarian cancer:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Exactly what causes ovarian cancer isn't known, but the greatest number of cases occurs in the fifth decade of life. However, it can occur during childhood. Other contributing factors include infertility; nulliparity; familial tendency; ovarian dysfunction; irregular menses; and possible exposure to asbestos, talc, and industrial pollutants.
Primary epithelial tumors arise in the ovarian surface epithelium; germ cell tumors, in the ovum itself; and sex cord tumors, in the ovarian stroma. Ovarian tumors spread rapidly intraperitoneally by local extension or surface seeding and, occasionally, through the lymphatics and the bloodstream. Generally, extraperitoneal spread is through the diaphragm into the chest cavity, which may cause pleural effusions. Other metastasis is rare.

About prevalence and incidence statistics:
The term 'prevalence' of Polycystic ovary syndrome usually refers to the estimated population
of people who are managing Polycystic ovary syndrome at any given time.
The term 'incidence' of Polycystic ovary syndrome refers to the annual diagnosis rate,
or the number of new cases of Polycystic ovary syndrome diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
