Instructions Need this in 1 to 2 paragraphs student has chosen vomitting as his subject requires citations and references In the readings this week, you explored some of the most common disorders. Choose one of the disorders from the Module Seven Disorders List PDF. Note: Your discussion thread title should be the name of the disorder. If possible, you should choose a disorder that has not been chosen by a peer. You can complete your initial post using bullet points or a short answer. In your initial post, discuss the following questions about your chosen disorder: Concept and Etiology: How does the disease affect the ear, nose, throat, and gastrointestinal systems in particular? How does it deviate from the definition of health discussed in Module One? Classification: How is the disease classified? Clinical Manifestations (Symptoms and Signs): What are the symptoms and signs of the disease or disorder? Be sure you understand the difference between symptoms (subjective) and signs (objective). Diagnostic Tests: What are some additional diagnostic tests that can be done to illuminate the diagnosis? For example, when you injure your ankle, they take an x-ray to determine if it is broken or sprained. Support your answer with relevant resources. Example/Layout Concept and Etiology Skin cancer usually affects the integumentary system, which consists of the skin, hair, nails and associated glands (ACS, 2021). Skin cancer is a type of malignancy that originates from the elevated growth of the skin cells even if stimulated by stress from DNA damage caused by ultraviolet radiation. Metastasis to nearby tissues or organs may affect muscles, bones, or joints in the nearby area (ACS, 2021). Etiology includes exposure to UV radiation, skin exposure, use of tanning beds and lamps, skin type and sensitivity, geographic location, and immunosuppression. Skin cancer deviates from the definition of health by its ability to meddle with normal cellular processes, developed symptoms and complications, compromised tissue architecture and function, and required toxic treatments that could be dangerous to overall health. Classification Skin cancer is divided into several types highly dependent upon its origin. The three main types are: Basal cell carcinoma: from basal cells in the bottom-most layer of the epidermis. Squamous cell carcinoma: from squamous cells in the upper layer of the epidermis. Melanoma: from within the melanocytes of the skin that produce pigments (ACS, 2021). Signs A mole or any other skin lesion that shows alterations in appearance, such as size, shape, and color. Abnormalities (e.g., new growths, sores) that do not heal. Symptoms Intermittently itching accompanied by tenderness or even pain. Oozing of blood or fluids through lesions' surface. Enlarged lymph nodes near the affected area suggest the spread of cancer. Diagnostic tests Dermatologists usually do a visual exam, take a sample of the lesion through biopsy and do some imaging studies (e.g. X-rays and scans) for diagnosis of skin cancer (ASPC, 2021). Additional diagnostic tests may include: Dermoscopy: Change in skin lesion with respect to structure and pigmentation. Imaging studies (e.g., ultrasound, MRI, CT scan): for potential metastasis to tissues or organs situated in the stationary field. Sentinel lymph node biopsy: A diagnostic step to quantify whether cancers in lymph nodes have also spread, commonly applied in cases of melanoma (ACS, 2021). These diagnostic tests are intended to confirm the accuracy of the diagnosis, to find how developed the disease is and to obtain the right treatment protocols. References American Cancer Society.
