Tumours of borderline malignancy
Tumours of borderline malignancy are epithelial tumours that don’t clearly appear to be cancerous. They account for approximately 15% of all epithelial ovarian tumours. They may occur in one or both ovaries.
These tumours are also known as:
- tumours or ovarian cancer of low malignant potential (LMP)
- borderline tumours
- atypical proliferative tumours
- borderline epithelial ovarian cancer
Tumours of borderline malignancy are different from typical ovarian cancers.
- Although the cells of the tumour appear malignant (cancerous), they have not invaded the underlying or nearby tissue.
- If they spread outside the ovary into the abdominal cavity, they may grow on the lining of the abdomen, but they don’t grow into it.
- The tumours grow slowly and most are stage I at diagnosis.
- The tumours tend to develop in women at a younger age than most ovarian cancers.
Types of tumours include:
- serous tumours
- mucinous tumours (gastrointestinal type or endocervical-like type)
- endometrioid tumours
- clear cell tumours
- transitional cell tumours (Brenner tumour) – usually benign
