The relationships between PCOS and endometrial, breast and ovarian cancer are complicated, needed examination of PCOS diagnostic criteria, confounding and mediating factors, co-morbid conditions, menopausal status, etiologic heterogeneity of cancer subtypes as well as management alternatives that may also impact cancer risk. Scientists believe it is the chronic exposure of estrogen to the endometrial lining that increases the risk of developing endometrial cancer. Polycystic Ovary Syndrome (PCOS) Endometrial Cancer Risk Factors And obesity is a known risk factor for endometrial cancer because it also increases estrogen levels. Cancer risk. POLYCYSTIC OVARIAN SYNDROME (PCOS) A meta-analysis of five studies totalling 4605 women reported the odds of developing endometrial cancer were three times higher in women with PCOS. 2A). A WARNING RE: ENDOMETRIAL ABLATION. 4 The key mechanism for the development of endometrial cancer is the triad of obesity, excess insulin in the blood (hyperinsulinemia), and diabetes, which are all commonly seen in PCOS. REVIEW Open Access Polycystic ovary syndrome and risk of endometrial, ovarian, and breast cancer: a systematic review Holly R. Harris1,2* and Kathryn L. Terry2,3 Abstract Background: Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with an estimated prevalence of The hormone imbalance of high estrogen and testosterone seen in those with PCOS causes anovulation, resulting in the uterine lining failing to shed each month. Risk of endometrial, ovarian and breast cancer in women with polycystic ovary syndrome: a systematic review and meta-analysis. Hormone levels play a big role in the development of endometrial cancer. For instance, some research has shown that risk of cancer of the endometrium (pronounced en-doh-MEE-tree-uhm), the inside lining of the uterus, may be higher for women with polycystic ovary syndrome (PCOS) than it is for women without PCOS. Larger well-designed studies, or pooled analyses, may help clarify these complex associations. The non-cancerous gynecological diseases, endometriosis, polycystic ovary syndrome (PCOS) and uterine fibroids, have been proposed as endometrial cancer risk factors; however, disentangling their relationships is complicated due to their shared risk factors and comorbidity. Moreover, this study found that CAM can reduce the serum testosterone level in PCOS patients with endometrial abnormalities. Endometrial cancers can be divided into two subtypes: type 1, which are estrogen dependent and comprise about 80% of all endometrial cancers, and type 2, which are non-estrogen dependent. PCOS treatment: When you know that the PCOS is the obvious reason for the risk of developing endometrial cancer, then, it should be treated first. Gestational diabetes (diabetes when pregnant)—which puts the pregnancy and baby at risk and can lead to type 2 diabetes later in life for both mother and child. Multiple studies reported that women with PCOS were at a higher risk for endometrial cancer; however, many did not take into account body mass index (BMI), a strong and well-established risk factor for endometrial cancer. The prescription of hormonal treatment to reduce the risk of this complication is supported by the Guidelines for Good Clinical Practice of . Since then several studies have been published that seem to support this association. The usual treatment for endometrial cancer is to undergo surgical removal of the uterus, known as a hysterectomy. PCOS is generally treated with the help of oral contraceptives.These medications are prescribed by doctor. A variety of factors can increase a woman's risk for this cancer.

The results of this large cohort study support those of case-control studies showing that women with PCOS are at increased risk for endometrial cancer, whereas their risks for breast and ovarian cancer are similar to those of women in the general population. It is a cancer that occurs in the uterus when the cells of the inner uterus lining start growing in an uncontrollable manner. Evidence from a big study in which 1270 women with chronic anovulation participated, the excess risk of endometrial cancer was identified to be 3.1(95% CI, 1.1-7.3)23. It is contradicted in women w/ PCOS & can mask sx's of endometrial cancer which we are at a much higher risk of contracting.

Sleep apnea raises your risk of heart disease and diabetes. Bottom line, while birth control pills can be very effective for regulating menstrual cycles, decreasing androgenic side effects, and for decreasing the risk for ovarian and possibly endometrial cancer, it may neglect addressing the underlying cause of pcos and may worsen metabolic profiles and certain symptoms in some.

Particularly women with high levels of circulating estrogen, like women with PCOS, are at increased risk. The authors identified eight studies to show that women with PCOS were more likely to develop endometrial cancer (odds ratio (OR) 2.70, 95% confidence interval (CI) 1.00-7.29) and ovarian cancer (OR 2.52, 95% CI 1 .

Gestational (pregnancy-related) diabetes and high blood pressure 2A). One of the most significant risk factors for endometrial cancer is increased estrogen levels when compared to progesterone. Researchers showed 4.8-fold risk of endometrial cancer and 10.8-fold risk of cancer in infertile patients with chronic anovulation. Hormonal birth control is able to ensure regular ovulation which decreases the risk of the user developing endometrial hyperplasia, or the buildup of uterine tissue. Although research has not found a direct link between PCOS and breast cancer, research has found a link between diabetes and breast cancer.

An additional proportion may be because of lack of physical activity. In women with PCOS intervals between menstruation of more than three months may be associated with endometrial hyperplasia and later carcinoma5,22. This in turn also helps reduce the risk of developing uterine cancer.

This may cause excessive thickening of the endometrium and heavy, irregular bleeding. There is insufficient evidence to implicate PCOS in the development of vaginal, vulval, cervical or ovarian cancers. Hyperandrogenism and hypersecretion of luteinizing hormone (LH) are common features in PCOS which result in overexpression of endometrial androgen receptors and endometrial cancer growth in-vitro .
