The goal of this clinical trial is to learn if adding cancer-specific amplitude-modulated radiofrequency electromagnetic field therapy (TheraBionic P1 device) to the treatment of resectable early-stage breast cancer will affect the pathological response.

RECRUITINGPathological Response to Treatment
Proportion of responders based on residual cancer cells in a resection specimen will be quantified. The response rate will be estimated as the proportion of patients who respond to treatment relative to all patients. The corresponding two-sided 95% confidence interval (CI) will be calculated using Clopper and Pearson's method
Time frame: At time of surgery (after approximately 2 weeks of treatment and tumor resection)
Changes in microRNA expression in tumor tissue
Changes in microRNA expression in tumor tissue pre- and post-treatment will be calculated as the difference between pre- and post-treatment expression values with two-sided 95% CI estimated using a standard t-distribution-based formula for paired differences.
Time frame: Baseline to post-surgical resection
Changes in Ki-67 expression in tumor tissue
Changes in Ki-67 expression in tumor tissue pre- and post-treatment will be calculated as the difference between pre- and post-treatment expression values with two-sided 95% CI estimated using a standard t-distribution-based formula for paired differences.
Time frame: Baseline to post-surgical resection
Changes in tumor apoptosis marker Cleaved caspase-3 (CC3) in tumor tissue
Changes in CC3 expression in tumor tissue pre- and post-treatment will be calculated as the difference between pre- and post-treatment expression values with two-sided 95% CI estimated using a standard t-distribution-based formula for paired differences.
Time frame: Baseline to post-surgical resection
Changes in cell cycle arrest marker p27 in tumor tissue
Changes in p27 expression in tumor tissue pre- and post-treatment will be calculated as the difference between pre- and post-treatment expression values with two-sided 95% CI estimated using a standard t-distribution-based formula for paired differences.

Time frame: Baseline to post-surgical resection
Overall survival (OS)
OS will be graphically summarized using Kaplan-Meier (KM) curves, with corresponding medians and two-sided 95% CIs computed using KM estimates. Additionally, OS rates at every six months post-treatment will be estimated using the KM estimated, with two-sided 95% CIs provided for each time point.
Time frame: Up to 5 years post-surgery
Progression Free Survival (PFS)
PFS will be graphically summarized using Kaplan-Meier (KM) curves, with corresponding medians and two-sided 95% CIs computed using KM estimates. Additionally, PFS rates at every six months post-treatment will be estimated using the KM estimated, with two-sided 95% CIs provided for each time point.
Time frame: Up to 5 years post-surgery
