My mom has been diagnosed with cancer, but she hasnt told me what kind it is. Shes said she has multiple tumors on her liver and abdominal cavity. She said something about that theyre not sure where it started, but she heard something about maybe it metastasized from the ovaries. Shes had fluid build up in her abdominal cavity, and they drained 1/2 of it (3 quarts) on Friday. She sees an oncologist on Monday, but I was trying to get an idea of how serious it is.
From the description you have given, it seems to be a stage 4 tumor which has metastasized to liver. The site of primary origin of tumor has to be determined. Cytological exam to look for malignant cells in the abdominal fluid (ascites) Chat Doctor.  A CAT scan of abdomen and pelvis and a chest radiograph will aid in looking for the primary tumor site. A needle biopsy of primary tumor (if located) should be done. If primary is not found than needle biopsy of liver metastasis with histopathological exam and immunohistochemistry IOC to determine primary tumor of origin will be required and will aid in treatment planning. Since it is stage 4, treatment will be palliative and is likely to be chemotherapy. Please discuss it with your oncologist.
