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.

Ovarian cysts:
Causes
(Professional Guide to Diseases (Eighth Edition))
Follicular cysts are generally very small and arise from follicles that overdistend. When such cysts persist into menopause, they secrete excessive amounts of estrogen in response to the hypersecretion of follicle-stimulating hormone and luteinizing hormone that normally occurs during menopause. (See Follicular cyst.)
Granulosa-lutein cysts, which occur within the corpus luteum, are functional, nonneoplastic enlargements of the ovaries caused by excessive accumulation of blood during the hemorrhagic phase of the menstrual cycle. Theca-lutein cysts are commonly bilateral and filled with clear, straw-colored fluid; they’re often associated with hydatidiform mole, choriocarcinoma, or hormone therapy (with human chorionic gonadotropin [hCG] or clomiphene citrate).
Polycystic ovarian disease is part of the Stein-Leventhal syndrome and stems from endocrine abnormalities.

Ovarian cancer:
Causes
(Handbook of Diseases)
The exact cause of ovarian cancer is unknown, but its incidence is noticeably higher in women of upper socioeconomic levels between the ages of 20 and 54. However, it can occur during childhood. Certain genes, including BRCA1 and BRCA2, may increase risk. Other contributing factors include age at menopause; infertility; celibacy; high-fat diet; exposure to asbestos, talc, and industrial pollutants; nulliparity; familial tendency; and history of breast or uterine cancer.
Primary epithelial tumors arise in the müllerian epithelium; germ cell tumors, in the ovum itself; and sex cord tumors, in the ovarian stroma (the ovary’s supporting framework).
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 types of metastasis are rare.

Ovarian cysts:
Causes
(Handbook of Diseases)
Follicular cysts are generally small and arise from follicles that overdistend instead of going through the atretic stage of the menstrual cycle. When such cysts persist into menopause, they secrete excessive amounts of estrogen in response to the hypersecretion of follicle-stimulating hormone and luteinizing hormone that normally occurs during menopause.
Granulosa-lutein cysts, which occur within the corpus luteum, are functional, nonneoplastic enlargements of the ovaries caused by excessive accumulation of blood during the hemorrhagic phase of the menstrual cycle.

Chronic fatigue and immune dysfunction syndrome:
Causes
(Handbook of Diseases)
Although the cause of CFIDS is unknown, researchers suspect that it may be found in human herpesvirus 6 or in other herpesviruses, enteroviruses, or retroviruses. Rising levels of antibodies to EBV, once thought to implicate EBV infection as the cause of CFIDS, are now considered a result of this disease.
CFIDS may be associated with a reaction to viral illness that’s complicated by dysfunctional immune response and by other factors that may include sex, age, genetic disposition, prior illness, stress, and environment.
