Ovarian cancer hormone-related

Taking the contraceptive hormones provides health benefits not related to contraception, such as regulating the menstrual cycle and decreased blood loss, and incidence of iron deficiency anemia, and dysmenorrhea Health benefits related to the inhibition of ovulation include a decrease in ovarian cysts and ectopic pregnancies. hi addition, there is a decrease in fibrocyctic breast disease, acute pelvic inflammatory disease endometrial cancer, ovarian cancer, maintenance of bone density, and symptoms related to endometriosis in women taking contraceptive hormones. Newer combination contraceptives such as norgestimate and ethinyl estradiol... 

With the identification and characterization of all members of the kallikrein gene family, accumulating evidence indicates that other kallikreins might be also related to hormonal (e.g., breast, prostate, testicular, and ovarian cancers) and other malignancies. KLK6 and KLK10 were originally isolated by differential display from breast cancer libraries [216],... 

Based on this concept of correlation between high replication rate/high persistent mutation risk, Pike et al. (1983) formulated the hypothesis of breast tissue age and developed a mathematical model to predict the effects of exposure to ovarian hormones. This model incorporates reproductive and endocrine items related to breast cancer and is able to predict the relative risk of individual situations with results that are very close to those observed in clinical trials. According to this hypothesis, both the years of exposure and the circulating serum levels of estrogens are associated to short-term breast cancer risk in postmenopausal women (Toniolo et al. 1995). 

Leuprolide acetate represents a gonadotropin-releasing hormone agonist tiiat acts as a potent inhibitor of gonadotropin secretion, used as part of the treatment of prostate cancer. Continuous administration results in the suppression of ovarian and testicular steroidogenesis due to decreased levels of LH and FSH with a subsequent decrease in testosterone (male) and oestrogen (female) levels. Leuprolide may also have a direct effect on the testes by a different mechanism not directly related to reduction in serum testosterone.
