The majority (approximately 90%) of ovarian cancers are sporadic and not associated with a known pattern of inheritance. Of the 5% to 10% that have a familial component, the majority are associated with the breast cancer susceptibility gene 1 (BRCA1) and a smaller number with mutations of the BRCA2 or mismatched repair genes (HNPCC syndrome). Low progesterone levels are not associated with ovarian cancers.
