This study involves female patients aged 18-70 years with breast cancer who are candidates for breast-conserving surgery. The main question it aims to answer is:\n\n\\- Can cell microscopic imaging provide accurate intraoperative assessment of surgical margins compared to standard frozen pathology?\n\nResearchers will compare the results of cell microscopic imaging to those of standard frozen pathology and paraffin pathology to see if the new imaging technology can effectively and quickly determine whether surgical margins are free of cancer cells.\n\nParticipants will:\n\n* Undergo breast-conserving surgery with standard pathological assessments.\n* Have their surgical margins evaluated using cell microscopic imaging during the operation.\n* Be monitored for postoperative recovery at regular intervals (2 weeks, 3 months, 6 months, and 12 months) after the surgery.",[52,53,54],"Breast-Conserving Surgery","Breast Carcinoma","Margins in the Specimen",[52,56,57,58],"Breast Cancer","Margins","microscope","NOT_YET_RECRUITING","2025-06-11",{"date":62,"type":63},"2025-06-19","ACTUAL",{"date":65,"type":46},"2025-07-01",{"date":67,"type":46},"2026-12-31",{"name":5,"class":6}]
