Stomach feels tight and bloated but dosent look bloated worried about ovarian cancer?

Proabably not. Most ovarian cancers don't reach enormous sizes to allow bloating or palpation. They metastasize readily and to a site of TGF-B, that is the omentum which produces a factor allowing ascetic fluid to fill the abdomen. At that time on palpation, the bloating is not from gas but from fluid distention. A qualified physician can tell on palpation or with somography if ovarian Ca is there.
