Lesions detected on core biopsy with features of ASCL carry a high risk of malignancy and should undergo surgical excision. In contrast, BSCL from core biopsy are frequently benign and those demonstrating low\u2010risk imaging features and benign core biopsy findings may be considered for surveillance. A multidisciplinary approach is essential for optimising outcomes in this challenging and uncommon subset of breast pathology.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ans.70948","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T06:21:21Z","timestamp":1788848481000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spindle Cell Lesions of the Breast: A 12\u2010Year Experience"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3601-4741","authenticated-orcid":false,"given":"Shalvin","family":"Jassal","sequence":"first","affiliation":[{"name":"Breast and Endocrine Surgery Unit Eastern Health  Melbourne Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wesley","family":"Tjang","sequence":"additional","affiliation":[{"name":"Monash University  Melbourne Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaun","family":"Monagle","sequence":"additional","affiliation":[{"name":"Department of Pathology Eastern Health  Melbourne Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Law","sequence":"additional","affiliation":[{"name":"Breast and Endocrine Surgery Unit Eastern Health  Melbourne Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4987-3430","authenticated-orcid":false,"given":"Justin","family":"James","sequence":"additional","affiliation":[{"name":"Breast and Endocrine Surgery Unit Eastern Health  Melbourne Australia"},{"name":"Monash University  Melbourne Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,7]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.5858\/133.9.1370"},{"issue":"6","key":"e_1_2_10_3_1","first-page":"e25702","article-title":"Spindle Cell Carcinoma in the Breast: A Case Report","volume":"14","author":"Ayyaz F.","year":"2022","journal-title":"Cureus"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978\u20100\u2010443\u201006652\u20108.50019\u20103"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.16.17610"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/his.12865"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/his.14091"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10549-007-9652-2"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40064-015-1480-y"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/1746-1596-1-13"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.1999.00766.x"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2015.11.023"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/jso.20110"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.213.3.r99dc20889"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.3122\/jabfm.19.2.161"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-019-06312-7"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2016.10.020"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/PAP.0b013e3182862846"},{"key":"e_1_2_10_19_1","volume-title":"Guidelines for Non\u2010Operative Diagnostic Procedures and Reporting in Breast Cancer Screening","author":"Ellis I.
