Phyllodes tumors can be very large and challenging to treat surgically in women with smaller breasts. Complete excision of the phyllodes tumor with grossly negative margins and a small amount of normal tissue circumferentially is necessary. Radical mastectomy or modified radical mastectomy should be avoided. Lymph node evaluation is not necessary.[9]
Source links and citations
Phyllodes tumors present a small risk of recurrence, as they fall into the intermediate-grade sarcoma category. These tumors do not metastasize, but they can recur locally.
