Can acid reflux be related to ovarian cancer?

Yes, indirectly: If ovarian cancer has progressed, with involvement of abdominal tissue and omentum, or if ascites has developed, it will increase intra-abdominal pressure, thereby increasing the possibility of reflux. There's no other direct relationship. Good luck.

No, not usually: Acid reflux is due to a weak muscle in your food pipe(esophagus). Ovarian cancer has no direct effect on it.
