CELLULAR ABERRATION PART I – NCM 112 A disease process whereby cells proliferate abnormally, ignoring growth-regulating Parts of the Cell signals in the environment surrounding the cells. Nursing Role in Cancer Care Multifaceted and overlaps with many other nursing specialties Occurs in: hospitals, clinics, rehabilitation centers, home care, and long-term facilities Diagnosis to end-of-life care. Precision Medicine Cell Cycle Advances in technology and biological Interphase research (like genome sequencing) G0, Normal Human Cells Identification of unique patient G1, Cell start to grow but some DNA, cell characteristics (genomics and cellular growth. profiles) S, Replication of DNA occurs Development of personalized, precise, and targeted treatment for cancer. Mitosis Modern approach to understanding health Prophase – chromosomes are condensed Connecting, Collecting, and Analyzing many Metaphase – Chromosomes align at the kinds of information based on the disease center that presented on the certain, specific client. Anaphase – The duplicated DNA Stop focusing on the general disease itself segregates but the client’s specific disease symptom Telophase – Chromosomes are Cancer Health Disparities decondensed Socioeconomic status Cytokinesis Race/Ethnicity Cell splits into two daughter cells Diet Stress Resting Phase (G0) Geography Cells may leave interphase and enter into a Pathophysiology non-dividing quiescent phase. Anaplasia. The pattern of growth in which cells lack normal characteristics and differ in shape and organization from their cell of origin. Genetic mutation of DNA Formation of the abnormal clone Proliferation of the abnormal clone Abnormal clone requires invasive characteristics. Metastasis Disruption of Cell Cycle = Abnormal Cell Growth Ability of cancer cells to penetrate lymphatic CANCER and blood vessels, circulate through the amlap bloodstream, and then invade normal Usually to the bone, brain, liver, and lung (to tissues elsewhere in the body. the highly vascular organs) Often causes generalized effects such as anemia, weakness, systemic inflammation, Tumor Angiogenesis weight loss, anorexia, and CAS.

No symptoms and more signs of plasma cells and proteins in the blood. Multiple Myeloma (MM). Symptoms throughout the body. Blood is full of cancerous plasma cells and proteins.
