Magbanua BSN 3C EPIDEMIOLOGY The leading causes of cancer-related death in the US in order of frequency and location: - Lung cancer - Prostate cancer - Colorectal cancer in men - Lung cancer - Breast cancer - Colorectal cancer in women PATHOPHYSIOLOGY 1. Begins when a cell is transformed by genetic mutations of the cellular deoxyribonucleic acid (DNA). 2. Genetic mutations may be inherited or acquired, leading to abnormal cell behavior. 3. The initial genetically altered cell forms a clone and begins to proliferate abnormally, 4. Evading normal intracellular and ABCDE’S OF MELANOMA extracellular growth-regulating processes or signals as well as the immune system defense mechanisms of the body 5. Genetic mutations may lead to abnormalities in cell signaling transduction processes (signals from outside and within cells that turn cell activities either on or off) that can in turn lead to cancer development. 6. Ultimately cells acquire a variety of capabilities that allow them to invade surrounding tissues or gain access to lymph and blood vessels, which carry the cells to CARCINOGENESIS other areas of the body resulting in metastasis or spread of the cancer. CHARACTERISTICS OF BENIGN AND MALIGNANT CELLS 3|RN2026 NCM112-N (LEC) Lance Rover L. Magbanua BSN 3C MOLECULAR PROCESS - Cell proliferation is how quickly a cancer Three step cellular process: cell copies its DNA and divides into 2 cells. 1. Initiation Process - Carcinogens such as chemicals, physical RISK FACTORS factors, or biologic agents, cause mutations - Older Age in the cellular DNA. - Genetics - Normally, these alterations are reversed by - Immunosuppression DNA repair mechanisms or the changes - Viruses initiate apoptosis or cell senescence. - Smoking - Cells escape these protective mechanisms - Sun Exposure with permanent cellular mutations occurring, - High-Fat, Low-Fiber Diet but these mutations usually are not significant to cells. 2. Promotion Process - Repeated exposure to promoting agents causes proliferation and expansion of initiated cells. - >>> Causing increased expression or manifestations of abnormal genetic information. - Thus, >>> Promoting agents are not mutagenic and do not need to interact with the DNA. - Promotion is reversible if the promoting substance is removed (a key focus in the prevention of cancer). 3. Progression Period - Altered cells exhibit increasingly malignant behavior. - These cells acquire the ability to stimulate ETIOLOGY angiogenesis (growth of new blood vessels Factors implicated or known to induce that allow cancer cells to grow), to invade carcinogenesis adjacent tissues, and to metastasize. 1.

Surgery - Removal of the entire cancer remains the ideal and most frequently used treatment method. 8|RN2026 NCM112-N (LEC) Lance Rover L. Magbanua BSN 3C - The removal of normal tissue beyond the tumor area decreases the possibility that residual microscopic malignant cells may lead to a recurrence of the tumor. Diagnostic Surgery - Performed to obtain a tissue sample for histologic analysis of cells suspected to be malignant. - Biopsy is taken from the actual tumor. - In some situations, it is necessary to take a sample of lymph nodes near a suspicious tumor. Biopsy Types 1. Excisional Biopsy - Used for small, easily accessible tumors. 2. Incisional Biopsy - Performed if the tumor mass is too large to be removed. 3. Needle Biopsy - Performed to sample suspicious masses that are easily and safely accessible. 4. Fine-Needle Aspiration (FNA) Biopsy - Involves aspirating cells rather than intact tissue through a needle that is guided into a suspected diseased area. 9|RN2026 NCM112-N (LEC) Lance Rover L.
