Pathophysiology
Clinical meaning
Breast Cancer Screening involves malignant transformation through accumulation of genetic mutations (oncogene activation, tumor suppressor loss) driving uncontrolled proliferation. The hallmarks of cancer include sustained proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion/metastasis. TNM staging guides prognosis and treatment decisions. Connect Breast Cancer Screening to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
