Their growth is limited and they never invade the supportive tissue of the ovary, called the stroma
They are also called low malignant (the possibility to become cancerous) tumours as they tend to grow slowly and in a more controlled manner when compared to cancer cells
If the borderline ovarian tumour is only within the ovary, and the patient wishes to have more children, fertility-conserving surgery can be done to save the other ovary, fallopian tube and the womb
There is no clear evidence on what the best follow up is for patients who have had a borderline ovarian tumour, but regular follow-up including hospital appointments and occasional scans is very important
