"Surgical excision with wide margin is the standard of care, typically a mastectomy. Axillary nodal dissection is usually not performed, as the malignancy features haematogenous spread."

"The tumours are of endovascular origin. There are two main types:"
"secondary breast angiosarcoma mainly involve the skin, with or without involvement of underlying breast parenchyma 11"
"The tumour may be mis-diagnosed on the basis of fine-needle biopsy; thus, core biopsy is mandatory for diagnosis 12."
