Article Abstract
Introduction: Breast cancer, one of the most aggressive types of cancer, poses significant challenges for diagnosis and treatment. Emerging as a promising biomarker, circulating tumor DNA (ctDNA) can be used to identify and monitor disease risk. This study sought to examine the impact of mutations in various genes on the progression of breast cancer. Genetic variants associated with breast cancer have been examined in individuals diagnosed with the disease worldwide.
Methods: Fifty female participants underwent breast cancer testing. Sanger sequencing was used to analyze peripheral blood DNA from these individuals to detect disease-causing mutations in the BRCA1, BRCA2, PTEN, TP53, and ATM genes. Genetic alterations linked to breast cancer were screened and the findings were compared with those of tumor genes.
Results: The development of hereditary/early onset breast cancer in this study was significantly associated with mutations in ATM, PTEN, TP53, and BRCA1/BRCA2, according to the analysis of sequencing data.
Conclusion: This study demonstrates the feasibility of analyzing ctDNA in patients with breast cancer (BC) undergoing palliative treatment using an SS-based technique.

Background: Breast cancer treatment, particularly during the perioperative period, is often accompanied by significant psychological distress, including anxiety and uncertainty. Mobile health (mHealth) interventions have emerged as promising tools to provide timely psychosocial support through convenient, flexible, and personalized platforms. While research has explored the use of mHealth in breast cancer prevention, care management, and survivorship, few studies have examined patients' experiences with mobile interventions during the perioperative phase of breast cancer treatment.

Oligomeric proanthocyanidins (OPCs), condensed tannins found plentiful in grape seeds and berries, have higher bioavailability and therapeutic benefits due to their low degree of polymerization. Recent evidence places OPCs as effective modulators of cancer stem cell (CSC) plasticity and tumor growth. Mechanistically, OPCs orchestrate multi-pathway inhibition by destabilizing Wnt/β-catenin, Notch, PI3K/Akt/mTOR, JAK/STAT3, and Hedgehog pathways, triggering β-catenin degradation, silencing stemness regulators (OCT4, NANOG, SOX2), and stimulating tumor-suppressive microRNAs (miR-200, miR-34a).
