Cancer pathology is a specialized branch of pathology focused on the study of neoplastic diseases. It investigates the structural, morphological, cellular, and molecular changes associated with cancer development, progression, and metastasis. This field employs microscopic analysis of tissue and cell samples, alongside molecular techniques, to diagnose cancer, determine its type and stage, assess prognosis, and identify predictive markers for therapeutic response, thus providing crucial information for patient management and cancer research.
