The word melanoma comes from the Greek words, melas (black) and -oma (tumour). It is a very serious cancer that most often occurs in the skin and less frequently in the eye or in the lining of the nose, mouth, or genitals. Melanoma begins in melanocytes, cells that make a pigment called melanin. Both light- and dark-skinned people have melanin, which gives colour to the skin, hair, and parts of the eye.
The skin is the largest organ in the body, so it isn’t surprising that skin cancer is the most common of all cancers. Melanoma is the least common form of skin cancer, affecting 4% of all cases but causing 79% of skin cancer deaths. The average age of people diagnosed with Melanoma is between 45 and 55, although 25% of cases occur in people under 40. About 10% of all people with melanoma have a family history of melanoma. You are at increased risk of developing melanoma if there is a family history of melanoma in one or more of your first-degree relatives like a parent, child, brother or sister.
The major environmental risk factor for melanoma is overexposure to ultraviolet (UV) radiation from the sun. People who have fair skin that burns or freckles easily need to be especially careful in the sun as protecting yourself against UV overexposure is an important way you can help reduce your risk of developing melanoma.
There are two common misconceptions about melanoma. The first is that melanomas develop only in sun-exposed areas of the body. In fact, melanomas can occur in areas not normally exposed to the sun, including the abdomen, genitals, and soles of the feet. The second misconception is that dark-skinned and Asian people are not at risk for the disease. In fact, one type of melanoma occurs most frequently in African American and Asian populations, developing on the palms, soles, and nail beds.
The first sign of melanoma is often a change in the size, shape, or color of an existing mole or the appearance of a new mole. Men most commonly develop melanoma on the trunk, particularly the back, and women on the legs or arms. Melanoma develops in a manner similar to other cancer types. A cell's DNA genes, which control cell division and reproduction, become damaged. The damaged genes cause the cell to divide and grow without control or order, eventually becoming a malignant tumor.
Communicable diseases are one of the major concerns in public health, as it poses a significant threat to the population. The study of epidemiology allows nurses to understand the cause of the disease and helps determine the levels of prevention to be implemented in order to limit the spread of the disease (Lundy & Janes, 2016). The purpose of this paper is to: a) use an epidemiological model to identify the organism involved in the case study, as well as its pathology, etiology, diagnosis, and prognosis; b) describe the distribution of health events within Schenectady; c) identify the determinants affecting morbidity and mortality; d) determine the deterrents that exists within the affected population; e) calculate the outbreak’s incubation period; f) identify the individuals affected during endemic levels; g) provide a list of foods that were most susceptible to mass contamination; and h) determine the people involved in the food borne outbreak and analyze the possible cause of this occurrence.
Melanoma is a non-communicable disease and according to the Melanoma Institute of Australia, is a malignant skin cancer that affects thousands of individuals. It is a prevalent and serious non-communicable disease, making it an important issue in Australia. Both a biomedical perspective and sociological perspective must be considered to enable health practitioners to have a deep understanding about melanoma, and thus allow them to develop efficient and effective treatment and prevention methods.
Maintaining an ethical culture has been a struggle for the company for decades but when Hugh Grant took over as CEO, he the reformed the companies ethical culture. Before Grant, Monsanto was knowingly polluting a creek in Alabama with toxic waste, as a result, the polychlorinated biphenyls levels were outrageously high and many fish became deformed. The company had been doing this for forty years, “Once the cover-up was discovered, thousands of plaintiffs from the city filed a lawsuit against the company” (Ferrell, Fraedrich, & Ferrell, 2017, p. 383). Consequently, trust amongst stakeholders was broken, the companies stocks was impacted, dropping nearly by 50 percent. Grant worked to turn the company around and did just that by focusing on GM foods. “Today, Monsanto employs approxi- mately 22,000 people worldwide. It is recognized as one of the 100 best corporate citizens by Corporate Responsibility Magazine”. (Ferrell, Fraedrich, & Ferrell, 2017, p. 384) Despite all the legal battles the company has faced and ethical blunders, the company today now does maintain a better ethical

Malignant Melanoma is a type of malignant cancer that affects the melanocytes. A melanocyte produces the pigmentation in our skin and melanin gives us the color to our skin. These cells occur in the skin and can be found in other parts of the body. It is important to realize that melanoma can begin in any part of the body that can contain a melanocyte. Melanoma is considered less common than other skin cancers. It is a cancer that can be very dangerous if not detected early. Although in most cases it is diagnosed in time and can be cured. Many people are diagnosed with this cancer and it is said that 160,000 cases are diagnosed a year. ( ). In men a common site is on their back and for a woman is on their legs.
When people are exposed to UV light, from the sun or, for example, in a tanning booth, the melanocyte cells make more melanin and pack together tighter, resulting in darker skin tones. If the skin is receiving too much ultraviolet light, the melanocytes may begin to grow abnormally and become melanoma during this process.
“Epidemiology is the study of distributing in determinants of disease and disability and populations” (Mausner & Bahn 1974). It’s a basic science of the public’s health and is a measured scientific control that relies heavily on data and study design. Those who study epidemiology focus on specific population and how disabilities and disease affect them. Epidemiological methods have been applied to infectious disease outbreak investigations, but also to studies of longer-term chronic disease investigations. The Behavioral Risk Factor Surveillance System is the largest telephone survey in the world. It’s used to determine the commandments of many health risk behaviors among populations. Surveys were developed and conducted to mon...
The family has influence on how the dependent which in this case is the adolescent behaves, thinks, feels, etc. The effectiveness of the therapy relies on the effort of the family to work together. Usually, the family comes into therapy blaming the dependent for his or her actions and fail to realize that the home environment is contributing to it. This can lead to the dependent feeling worthless and creating more problems in the family. Family therapy changes the family dynamic by creating rules and boundaries in the house. The therapist creates interventions for the family during therapy to work on these issues (Szapocznik,
Over all, skin cancer is known to be a very common and dangerous cancer among the U.S.. Although there is no superior or particular cause known for it, it can be reduced by reducing radiation exposure from the sun and also tanning booths and beds. If not attempting to prevent it by staying out of the sun, and seeking not seeking shade and so forth, protection such as longer clothing garments that better cover the body as well as hats and sunglasses can help to eliminate direct exposure and reduce some of the damages that may occur. Certain amounts of sun light are healthy for the body as it provides vitamin- D which the body needs to maintain a healthy life style, though it is crucial not be over exposed as reverse side affects may occur, causing more harm than good.

Types of skin cancer are melanoma, and non-melanoma, which are basal cell carcinoma and squamous cell carcinoma. Melanoma is the rarer of the types and begins in the melanocytes or pigmented cells of the skin (National Cancer Institute, 2013). It is more serious than non-melanoma cancers because it can spread to other areas of the body. Non-melanoma cancers are more common and begin in the basal and squamous layers of the skin (National Cancer Institute, 2013). It is rare that this type of cancer spreads to any other area of the body.
The first notable case of epidemiologic investigation occurred in London in 1854. A British physician named John Snow surveyed townspeople and analysed data to determine that cholera was the result of polluted drinking water. (Schneider, 2014 p. 48). This technique is a common practice for epidemiologists. When an epidemic erupts, they will survey the infected to determine similarities and narrow down the search, and then collect samples in the field to pinpoint the
Skin Cancer is caused by hereditary factors, overexposure to the sun, and weak immune systems. (“Skin Cancer” infotrac.com) One reason people tend to get skin cancer is when someone in your family has passed their genes down to you, known as hereditary. Normally hereditary is one of the causes in the development of melanoma. For all types of skin cancers, overexposure of the skin to UV radiation in sunlight is the most frequently blamed source of skin cancer. “Research suggests that sunburns received early in one’s childhood can lead to skin cancer later in life” (“Skin Cancer” infotrac.com). For example, when someone gets sunburned, you usually don’t know till ten to twenty years after and that’s why people don’t get skin cancer till they reach their twenties.
In an effort to analyze the natural history of a disease, an epidemiological triangle is used. An epidemiological triangle is comprised of a susceptible host or individual, environment, and a causative agent. The host tends to have low immunity, poor nutrition, and a concurrent disease. The host tends to have poor
