I Was Put In The Hospital And Thursday My Blood

I was put in the hospital and Thursday my blood test they said I had fourth stage cancer. But know mast or tumors can be founded. They said the highest of the number that they think it's ovarian cancer and they can't find my ovarias. I'm wonder should I get a second opinion. They are going to have pet scan run but that in two weeks. It will be almost a month by then and I feel maybe I've should of been on medicine instead of just letting it go.
