I had a CT scan the other day looking for ulcers. (I've had abdominal pain, bowel changes, etc) They found uclers but also said there was a questionable problem with ovaries. They found a cyst on the right ovary and a mass on the left. Why would they use two different wordings for a cyst, i.e. mass? I am scheduled for ultrasound tomorrow. What I wanted to know is can a transvaginal ultrasound be done during a period? Also, since they used the word mass does that indicate something more serious? Needless to say, I am confused as to what is going on. I have had irregular periods for quite awhile ( I thought nothing of it, I am 43 years old and thought menopause is probably right around the corner) I am tired a lot, but I am also a wife and mother and work. Will I know the results right away. Thank you, in advance. As you can tell many things are going through my mind.
