Questions about my diagnosis

Hello Ladies,
My question today is;
I originaly had a cyst/tumour removed, the patholoy results showed a mixture, of malignant, benign, and borderline cells. It was a mucnous carcinoma. Only a small amount of malignant cells, but the actual tumour was pretty big, on the scan the solid area appeared very small in relation to the size of the tumour.

When I had my hysterectomy they said there was borderline cells in the 1 ovary.

Is this a borderline tumour?
or a borderline that has turned malignant?
Or just a mucinous carcinoma?

Many Thanks
Helen
