Causes

Ovarian cancer is the fourth leading cause of cancer death in women, the leading cause of death from gynecologic malignancies and the second most commonly diagnosed gynecologic malignancy . It is idiopathic, meaning that the exact cause is unknown. The disease is more common in industrialized nations, with the exception of Japan. In the United States, females have a 1.4 % to 2.5 % (1 out of 40-60 women) lifelong chance of developing ovarian cancer.

Older women are at highest risk. More than half of the deaths from ovarian cancer occur in women between 55 and 74 years of age and approximately one quarter of ovarian cancer deaths occur in women between 35 and 54 years of age.

The risk for developing ovarian cancer appears to be affected by several factors. The more children a woman has, the lower her risk of ovarian cancer. Early age at first pregnancy, older ages of final pregnancy, and the use of some oral contraceptive pills have also been shown to have a protective effect. Ovarian cancer is reduced in women after tubal ligation.

The link to the use of fertility medication has been controversial. An analysis in 1991 raised the possibility that use of drugs tation may increase the risk for ovarian cancer. Several cohort studies and case-control studies have been conducted since then without providing conclusive evidence for such a link with the possible exception that prolonged use (> 1 year) of clomiphene citrate should be avoided.1 It will remain a complex topic to study as the infertile population differs in parity from the "normal" population.

There is good evidence that in some women genetic factors are important. Carriers of certain mutations of the BRCA1 or the BRCA2 gene (especially Ashkenazi Jewish women) are at a higher risk of both breast cancer and ovarian cancer, often at an earlier age than the general population. Patients with a personal history of breast cancer, or a family history of breast and/or ovarian cancer, may have an elevated risk. A strong family history of uterine cancer, colon cancer, or other gastrointestinal cancers may indicate the presence of a syndrome known as hereditary non-polyposis colon cancer (HNPCC), which confers a higher risk for developing ovarian cancer. Patients with strong genetic risk for ovarian cancer may consider the use of prophylactic oophorectomy after completion of child-bearing.

Other factors that have been investigated, such as talc use, asbestos exposure, high dietary fat content, and childhood mumps infection, are controversial and have not been definitively proven.

A study funded by American Cancer Society conducted at the H. Lee Moffitt Cancer Center of the University of South Florida has found a correlation between high levels of lysophospholipids (a type of fatty acid) with ovarian cancer patients and low levels of lysophospholipids with healthy women. This potential biomarker can be detected by a simple blood test. The blood test was 93 % accurate as predictor of ovarian cancer with less than 4 % false positives of the 117 women studied. Other indicators of ovarian cancer could be used to increase accuracy to 100 %. 2

Plenty of women's health books discuss ovarian cancer symptoms and treatments--but how do women diagnosed continue their lives? Guide To Survivorship For Women With Ovarian Cancer tells how to live life well after diagnosis. Two Johns Hopkins gynecologic oncologists and a clinical nurse emphases living life well in the face of the uncertainties ovarian cancer brings. Yes, the latest developments in diagnosis and treatment are discussed--but even more so, is the quality of living itself: it's this which sets Guide To Survivorship For Women With Ovarian Cancer apart from the others on the topic of ovarian cancer.
