Cancer arises from genetic and epigenetic changes that drive uncontrolled cellular proliferation and tissue invasion. This book examines the pathological features of neoplasia, from molecular alterations to systemic manifestations. It covers tumor classification, histological grading, and staging, along with mechanisms of metastasis and angiogenesis. Each chapter addresses specific organ systems, presenting common and rare malignancies with diagnostic hallmarks. Immunohistochemistry, molecular profiling, and tumor markers are discussed to aid in personalized diagnosis. Clinical implications such as paraneoplastic syndromes and treatment responses are included. The content is supported by high-resolution images and diagnostic flowcharts to enhance clinical pathology competence.
