The term sex cord refers to an embryonic structures that develop into ovarian follicles and stromal cells are the connective tissue of any organ. (osmosis.org)
So a sex cord-stromal ovarian cancer is a type of tumor that develops from either ovarian follicle cells or connective tissue cells . (osmosis.org)
If any of those cells starts to divide uncontrollably, it can either form a benign tumor which means that it doesn't invade nearby tissue or spread to other parts of the body , or it can be a malignant tumor which means that it can invade nearby tissue and spread to other parts of the body .
