Disease detail: I have an Ovarian Cyst. What does this mean?
It began for me with changes to my menstrual cycle. I am always fairly regular give or take a few days in getting my period on time. But this time two weeks went by with no visit from "aunt flow" and I was becoming worried. The obvious thing which comes to mind when your period is late is to wonder if you are pregnant. So I went off to the gynecologist where they promptly gave me a pregnancy test which turned out to be negative.
I was also experiencing some pressure in my abdomen especially on my bladder and so my doctor decided to do an ultrasound to see what was going on down there. When the doctor looked at the results he told me that I had a cyst on my right ovary. Of course the first words out of my mouth were, "Does this mean I have ovarian cancer?" and his reply was to re-assure me that this was a "simple cyst" and should go away within a couple of cycles at most. I must have still looked worried as the nurse chimed in, "Oh yeah I get these kind of cysts all the time, nothing to worry about."
I was asked to come back in four weeks for another ultrasound and by then the cyst had resolved. I was relieved. And on day 55 of my cycle my period did return.
I think a lot of women are like me and become anxious when they hear the words "ovarian cyst" but the reality is that the vast majority of ovarian cysts are benign and not cancerous.
