Hello, I have been having symptoms of ovarian cancer. They did a vaginal ultrasound and fid find s small fibroid in the top part of my uterus. But they could not see the ovaries do to gas, but said no free fluid and no masses seen. I went to my doctor and she still is not ruling out ovarian cancer. I am scheduled next Monday for a pelvic cat scan. I am worried a lot. Since no masses were seen, and the ovaries were not seen, wouldn t you still be able to see s mass on my ovaries through the gas? And the tech seemed to think he had really good pictures. I am very concerned. I am bloated, have to urinate all the time, having a lot of diarhrea I gave discomfort right under my stomach in the pelvic region. I would like your opinion Thank you.
