They initally told us not to be concerned with a finding of a tumor in my abdomen back in Dec. As I continued to not feel comfortable with the wait and see approach. We pushed forward for some concret answers, worked our way through 4 doctors and several tests and 1 surgery, we finally have an answer of leiomyosarcoma. Luckily with our fortitude we caught it early and we do not need chemo or radiation, just more surgery.
If you aren't comfortable then push forward for the answers you need.
Good luck
