can ovarian cancer cause heart palpitations? Susan 53, 2 sons, 2 miscarriages, partial hysterectomy due to cysts. Cysts off and on on ovaries over the years. I have had gas, bloating, a feeling of fullness on a light meal. Major hot flashes (yes in menopause for 7 years now) and night sweats. Lately I've had an odor in the female area that's not normal for me. Kind of rancid. And I get frequent heart palpitations, that are getting a bit scary. I'm a previous smoker. Quit six months ago.
