Lisa girl, you get yourself to a doctor for a second opinion...even a third if you have to. Ovarian cancer is definitely NOT something to fool around with. The longer it takes to diagnose it, the worse it gets. This is not meant to scare you, only to say the truth about what it sounds you might be dealing with.
Age has absolutely nothing to do with whether you can or cannot get ovarian cancer, and from what you say about your family's background...I would say that it's a definite possibility.
In an interview that Fran Dressler (not sure about the spelling, but you know who I mean...the woman who played "The Nanny" on TV) she said it took her two years and going to nine doctors before one of them was finally able to tell her what was wrong!
Don't just sit around worrying about it -- do something about it -- now! Who knows, it may not be ovarian cancer, but it's much better to be safe than sorry. As for me, I would rather know what's going on...then I can ready myself for what needs to be done next.
I love you, my sister. Please let us know what's happening, all right?
