Skin cancer is a disease in which cancer (malignant) cells are found in the outer layers of your skin. Skin cancer can be caused in different ways. Malignant Melanoma is the most serious of the common skin cancers. You can check for symptoms for skin cancer. There are different treatments used in skin cancer. There are also different ways to prevent skin cancer.
Skin cancer can be caused in different ways. The leading cause of skin cancer is caused by long term over exposure to the sun's ultraviolet rays. Damaging the ozone layer causes a higher level of UV light to reach the earth's surface. Skin cancer can be hereditary. You can easily develop skin cancer.
Repeated exposure to the sun's damaging ultraviolet light can cause skin cancer.
Ultraviolet light injures the DNA in skin cells, which then directs the cells to commit suicide (Fackelmann 422). People who work outdoors such as farmers and sailors are more likely to get skin cancer then people who are indoors most of the time. Most people receive 80% of their lifetime exposure to the sun by the age of 18 (Silverstien 40).
Damaging the ozone layer causes a higher level of UV light to reach the earth's surface. The ozone serves as a filter to screen out and reduce the amount of UV light that we are exposed to. Pollution from the earth thins the ozone layer. As the ozone layer is reduced, the earth's surface is exposed to more of the shorter UV wavelengths of the sun's radiation that damage living things. For each 10 percent depletion of the ozone layer, we can expect 20 percent more radiation in these damaging wavelengths ("An Introduction to Skin Cancer", 1997).
Skin cancer can be hereditary. If you have a history of skin cancer in your family, then you are probably at a higher risk. The p16 gene appears to be linked to inherited melanoma. Other genes have been associated with skin cancer, but tests are not yet on the market. In other words skin cancer can be carried in a gene (Rubin 66).
You can easily develop skin cancer. There are also other ways to develop skin cancer. It is becoming so common in the U.S. Just being outside for short periods each day without sunscreen, is your stardom to developing skin cancer. Most people don't even think they are at risk, but in reality we all are.
Malignant melanoma is the most serious of the common skin cancers. Malignant melanoma first appears as a light brown to black irregularly shaped blemish. The first symptom noticed by patients is growth. Some patients use surgery for treating malignant melanoma. Others use biological therapy.
Malignant melanoma is more serious than squamous cell carcinoma and basal cell carcinoma. Melanoma is a malignancy whose progression is analogous to other solid tumors such as colon or breast. Except for lung cancer in women, the incidence of melanoma is growing faster than any cancer in the United States. It is increasing at an alarming rate of 4 to 5 percent per year. It has become one of the more common cancers among young adults aged 20 to 40, accounting for up to one-third of all cancer cases among that age group (Mullins, 1996).
Malignant melanoma first appears as a light brown to black irregularly shaped blemish. It may also arise in a mole - a junctional or dysplastic mevus -, which has been present for some years.7 Melanoma can also appear on the body as a new mole. Men most often get melanoma on their trunk or on their head or neck. Women most often get melanoma on their arms and legs ("An Introduction to Skin Cancer", 1997).
The first symptom noticed by patients, in melanoma, is growth. If a mole grows so rapidly and doubles its size in three to six months, then it may be malignant. It is important to note the direction of the growth in malignant melanoma. Usually, the melanoma starts its spread outwards, as a flat, enlarging, stain on the skin and you will find difficulty in feeling its whereabouts when you pass your fingers over the area with you eyes closed. This is called horizontal growth in the skin and it is the very earliest stage of malignancy ("Malignant Melanoma", 1996).
Surgery is the primary treatment
