Aetiology
Benign phyllodes tumours of the breast are uncommon tumours that are believed to arise due to a combination of environmental and genetic factors. These tumours are not related to any known inherited gene mutations, and their exact cause is unknown.
Diagnosis
Benign phyllodes tumours can be diagnosed by physical examination and imaging studies such as mammography, ultrasound, and magnetic resonance imaging (MRI). A biopsy may also be needed to confirm the diagnosis.
Differential diagnosis
Differential diagnosis may include other benign and malignant tumours of the breast such as fibroadenoma, fibrocystic disease, and ductal carcinoma in situ (DCIS).
Treatment
Benign phyllodes tumours can be treated with surgery, which may involve removing the entire tumour or just the lump. Radiation and chemotherapy may be used in some cases.
Prognosis
The prognosis for benign phyllodes tumours is generally good, and the tumours rarely recur after they have been removed. However, it is important to monitor the area for any changes or recurrence.
