All your history and clinical features suggest towards ovarian cancer
.The CT guided biopsy
might have been taken from a peritoneal deposit. A small hematoma
at the area of biopsy is common which may need local compression and ice packing. If infection is suspected then you may need an antibiotic. Local wound cleaning with antiseptic solution is must. You may be started on chemotherapy
if the biopsy turns out to be positive for cancer. This may get delayed if you develop any infection. All the best.
