A Novel Intraoperative Fluorescence-guided System for Evaluating Margins During Breast-conserving Surgery for Breast Cancer

The goal of this clinical trial is to learn if a novel intraoperative fluorescence-guided system (EndoSCell Scanner) can help surgeons more accurately remove all cancerous tissue during breast-conserving surgery in female patients aged 18 years or older, with primary breast cancer. The main questions it aims to answer are: * Does the use of the EndoSCell Scanner system lower the rate of secondary surgeries needed due to positive cancer margins after the initial operation? * How accurate is the EndoSCell Scanner system in detecting residual cancer cells on the walls of the surgical cavity during the operation? Researchers will compare the surgical outcomes using the EndoSCell Scanner guidance to the expected outcomes from standard surgical practice without this technology to see if the system is effective. Participants will: * Receive their planned breast-conserving surgery (lumpectomy). * Have their surgical cavity scanned with the EndoSCell Scanner device after the main tumor is removed. * Have additional tissue removed from the cavity wall if the scanner indicates a potential cancer residue.

IntraOperative UltraSound Guided vs Wire Guided vs Magnetic Seed Guided Breast-Conserving Surgery for Non-palpable Tumors

This is a multi-center, randomized, open-label clinical trial that will enroll 1302 adult patients with non-palpable breast lesions. Participant eligible for the study will be randomized in a 1:1:1 ratio to one of the pre-surgery lesion localization: IOUS HydroMark™ (experimental arm A), magnetic Sirius Pintuition Seed® (experimental arm B) and the wire localization technique (control arm). The randomization will be stratified by lesion type (solid non-palpable (type B); non-solid non-palpable (e.g., microcalcification clusters, architectural distortive areas) (type C); post-NACT residual lesions (type D), and clinical center.

Comparative Research on the Accuracy of Margin Interpretation in Breast-Conserving Surgery for Breast Cancer: Cell Microscopic Imaging and Standard Frozen Pathology

The goal of this clinical trial is to assess whether cell microscopic imaging can accurately determine the tumor-free status of surgical margins in breast cancer patients undergoing breast-conserving surgery. 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: \- Can cell microscopic imaging provide accurate intraoperative assessment of surgical margins compared to standard frozen pathology? Researchers 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. Participants will: * Undergo breast-conserving surgery with standard pathological assessments. * Have their surgical margins evaluated using cell microscopic imaging during the operation. * Be monitored for postoperative recovery at regular intervals (2 weeks, 3 months, 6 months, and 12 months) after the surgery.
