Either way, your doctor is signaling that the problem appears self-contained. If benign,
curable because the cysts/tumors will have been removed. If cancerous,
curable because it's self contained and therefore early stage.
Since you're using a gyn/oncologist, you should be in good hands. They are specially trained to deal with these surgeries and that's a plus, even if you get a benign report.
Good luck and try not to worry while you're waiting.
