Anon - I'm glad to know your mom has such a strong, loving daughter. Together the two of you are going to pull through this. One of the first things to do is to learn more about ovarian cancer so that you and your mom are fully prepared to ask the right questions when she meets with the doctor on May 12. If you can go to the appointment with her, and take notes, it will be very helpful. If she does have cancer you will likely find that things will move very quickly right away, so you may want to do some preparations in advance or at least think about what would need to be done to help your mom if she needed to be hospitalized and have surgery and then follow up treatment. Right now it's hard to say how she would be treated, but when you have more information about her exact diagnosis it will be easier to get more information on what to expect. Make sense? There are many wonderful support organizations for ovarian cancer patients whose members are available to help you and your mom through this.
I'm going to put some links to information below. Please read these for yourself and for your mom. Feel free to come back with questions as you need to. We will be here for you.
How do you deal with something like this? With love, support and great big ears. The worst thing to do for someone with cancer is to focus on yourself, or to tell them you know how they feel. By helping your mom deal with this - though being her researcher, advocate, listening ear, and more, you'll do a world of good.
Take care of yourself, and keep in touch. Pat
