My 7 yr old Kelpie Ginger had surgery for a mast cell tumor on her right hind leg Biopsy report says: 1. "Surgical margins incomplete".............. My question-Does "incomplete" mean positive 2. "The MST extends to one of the cross-sectional cutaneous margins and to the deep margins and entire excision cannot be verified".. .........My question-Does "cannot be verified" mean tumor not entirely excised or unable to tell whether entirely excised? Can anyone help me with this? Bob in the USA
