¶ … Skin cancer [...] disease, its diagnosis, how it is treated, the different forms, and the causes of the disease. Skin cancer is a growing problem in society because so many people misunderstand it. It is also the most common form of cancer, so more needs to be done to educate people about the dangers of skin cancer to help control the disease and its spread.
In 1993, it was estimated that 700,000 new cases of skin cancer would be diagnosed (Sherry 81), and every year the numbers get larger, according to the Skin Cancer Foundation, a worldwide group working to treat and prevent the disease. In addition, "About 41,600 Americans were diagnosed with malignant melanoma in 1998, and 7,300 died from the disease" (Goff 28). These numbers have increased dramatically since 1930, and it seems as more Americans have fun in the sun, they will pay later when skin cancer attacks. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Each one has slightly different characteristics, but they are all dangerous, especially if left untreated.
Basal cell carcinoma is the most common form of skin cancer. It usually occurs in men over 40 years old, and rarely occurs in blacks. These cancers are usually small and oval-shaped, and sometimes red or pink colored. They are often waxy and hard, and they are usually removed surgically, which cures about 95% of cases. If these cancers go untreated, extensive surgery may be needed or even radiation treatment (Sherry 83-84). These cancers affect men more often than women because men tend to be employed in more outdoor occupations with more exposure to the sun, the main cause of skin cancer. In addition, these cancers usually occur in the area of the face, especially the ears and mouth (Helm 21).
Squamous cell carcinoma is the second most common form of skin cancer. These types of cancers mostly affect the same population as basal cell, but the appearance is different. These cancers are usually rough and red, and can be crusty or an open sore. Squamous cell can grow and spread quite quickly, and it can attack deeper tissues in the skin. Surgery is also the most common form of treatment for this type of cancer. The surgeon removes the tumor, and surrounding skin to make sure it does not spread any further. Surgery cures about 90% of patients, and the remaining ten percent may have to have chemotherapy to halt the rapid spread of the disease (Sherry 84). This form of cancer results in about 2,300 deaths every year, and they can occur just about anywhere on the body (Helm 21).
Finally, melanoma is the third most common form of skin cancer, but it is becoming increasingly prevalent, and many scientists expect it to reach epidemic proportions if the public does not become more aware of it, and the dangers of exposure to the sun. It is the most deadly form of skin cancer. It occurs in skin cells that have pigment, and this form of skin cancer often attacks younger patients than the other two. It also attacks both men and women, and rarely occurs in Asians or blacks. It also seems to run in families, but scientists do not know why. It also seems to be more prevalent in those with blonde or red hair, have freckles in certain areas, and suffered at least three blistering sunburns before the age of twenty (Sherry 86). Author Sherry notes, "Any person claiming two of these factors runs a melanoma risk that is 3.5 times greater than that of the general population; three or more of these factors increases the probability to 20 times the average risk" (Sherry 86). This cancer also seems to be prevalent in those patients who have a large number of moles. These melanomas resemble moles, but are different in several ways. They are asymmetrical, uneven in color, are usually larger than the size of a pencil eraser, and their edges are indistinct or blurry (Sherry 86). If the moles are removed early enough, 95% of melanoma patients face an excellent prognosis. However, if the melanoma has spread, the patient can face a far less favorable prognosis. Melanomas are measured in stages, from Stage I to Stage IV, and if the cancer has progressed to Stage IV, the patent may have only a five percent success rate (Sherry 86-87). Surgery is used to remove the cancer and surrounding skin...
Skin Cancer Describe the pathophysiology of the general process of abnormal cellular growth as it relates to all types of cancer. Normal cells become cancer cells because of DNA damage. In cancer cells, damaged cells are not repaired and they do not die; instead, the cells reproduce damaged cells. These cells grow out of control and invade other tissues (American Cancer Society, 2013). Compare and contrast the pathophysiology of basal cell carcinoma, squamous
Merkel Cell Carcinoma is a relatively rare, but highly aggressive type of skin cancer. Discovered in 2008, it is typically caused by a virus known as Merkel Cell Polyomavirus (MCPyV). At times, the disease may be known as APUDoma, a primary neuroendocrine carcinoma of the skin, or primary small cell carcinoma. However, from a pathological perspective, 80% of Merkel Cell Carcinoma (MCC) are called by the polyomavirus. Interestingly, the virus
, about 700,000 deaths per annum); Bone (Leukemia) (cancer of the blood or bone marrow and characterized by an abnormal proliferation of white blood cells); Lymphoma (Lymphatic) (cancer that begins in the lymphocytes of the immune system then presents as a solid tumor, many types, many treatments); Brain (Neuro/Nervous) (abnormal growth of cells within the brain, can be cancerous or non-cancerous, 50,000 U.S. cases per annum, 13,000 deaths per annum);
In the tissue culture, they usually proliferate indefinitely. The normal constraints which limit the growth of the cells absent in the cancerous state and are also characterized by the division ability for number of generations which is unlimited. Cell cycle and cancer With millions of chemical reactions taking place concurrently and in specific areas, the human body can be thought of as a small laboratory. It is the only "machine" with
" He believed that discovery of such cancer was vital to early identification of cancer risk in patients with family history of cancer. The two more prominent types were breast and colon cancer. Even though medical community considers a patients with family history of breast or colon cancer high risk, there is a common tendency to not focus too much on hereditary aspect. While this may have opened new avenues
