Low- only removed if causing symptomatic or aesthetic issues
What are phyllodes tumours?
Fibroepithelial tumours- epithelial and stromal tissue
How do phyllodes tumours present?
- Like fibroadenomas- highly mobile and well-defined
- Grow very fast
What is the malignant potential of a phyllodes tumour?
- High - a third have malignant potential
How are phyllodes tumours treated?
Wide local excision to prevent recurrence
What is a fibroadenoma?
- Proliferation of stromal and epithelial tissue of duct lobules
