7cm complex ovarian cyst, and complex right ov cyst, dilated tube w/debris, pelvic fluid cause abdominal bloating? doctor is concern for ovarian canc.

Yes...: Tubal and ovarian masses can cause abdominal bloating. Most ovarian masses (75%), regardless of size, are benign (not cancer). There are many causes of complex tubo-ovarian masses including ectopic pregnancy, infections (abscess), normal physiological process (post ovulation bleeding), etc.; that are not cancer. It is good that you have a clinician following you.
