Chapter 16: Cancer Nursing Care

Cancer Nursing Care examines cancer as a complex collection of diseases characterized by uncontrolled cellular proliferation and its multifaceted impact on patients and healthcare systems. The content begins with cancer epidemiology, exploring incidence patterns, survival rates, and mortality statistics while emphasizing the critical role of prevention and early detection strategies. The biological foundations of cancer are thoroughly explained through cellular dysfunction mechanisms, including disrupted cell cycle regulation, genetic mutations affecting proto-oncogenes and tumor suppressor genes, and the progressive stages of carcinogenesis involving initiation, promotion, and progression phases. Key pathophysiological processes such as angiogenesis, metastatic spread through hematogenous and lymphatic pathways, and tumor marker identification are detailed alongside immune system interactions including immunologic surveillance and tumor escape mechanisms. The chapter provides extensive coverage of cancer classification systems, distinguishing benign from malignant neoplasms through histologic grading and staging methodologies like the TNM system. Diagnostic approaches encompass tissue biopsy techniques, advanced imaging modalities, cytological examination, and genetic testing protocols. Treatment modalities receive comprehensive attention, including surgical interventions for curative and palliative purposes, chemotherapy classifications covering alkylating agents and antimetabolites with their cell cycle-specific mechanisms, radiation therapy principles including external beam and brachytherapy approaches, immunotherapy innovations featuring monoclonal antibodies and checkpoint inhibitors, targeted therapies utilizing kinase inhibitors and angiogenesis blockers, and hormone therapy applications. The nursing management focus emphasizes systematic approaches to managing treatment-related complications such as bone marrow suppression, gastrointestinal toxicities, fatigue management, alopecia concerns, organ-specific toxicities including cardiotoxicity and nephrotoxicity, cognitive changes, peripheral neuropathy, and recognition of oncologic emergencies including superior vena cava syndrome, spinal cord compression, and tumor lysis syndrome.
