Hi Gloria:
I am sorry that you have to have 2 surgeries.
I also had to have 2 surgeries, exactly one month apart. The first one was done with a scope (LAVH) where they removed my ovaries, uterus, etc. thinking my ovarian masses were not malignant. When they later found out that they were malignant, I had the laparotomy (the vertical incision) done.
They needed to do the laparotomy as that is the only way that they can formally "stage" your cancer. They have to biopsy all the surrounding areas including any fluid, lymph nodes, etc. This way they can know for sure that your cancer hasn't spread anywhere.
Also, if you don't have the "staging" surgery done, you will never qualify for clinical trials should you ever need them. This is what my oncologist told me when it happened to me.
Needless to say, having another surgery isn't fun, but it is so very important to know for sure if it has spread or not. That way they can tailor your treatment to your situation.
It sounds like you have a good doctor who is not taking any chances. If your cancer is localized and a low malignant type, you may not even have to have anything else done after this surgery.
Keep your spirits up, think positive and keep us posted.
