A Theory of the Cause of Skin Cancer Essay

Many people think that is it possible to achieve a “healthy tan,” but this thought has been proven wrong. Overexpose to UV-A and UV-B rays from the sun lead to premature aging of the skin, as well as the possible formation of skin cancer, know as melanoma. An appearance of a tan is actually a stage of burning and damage to the skin. Although a tan may be desirable to many, the fact remains that more people need to be educated on the dangers of the sun’s harmful rays, and the possible health complications of overexposure.

Skin cancer is a condition where cancerous cells form in the epidermis. The epidermis is the first layer of your skin. Melanoma can be on any part of the body (Egan 23-24). This form of skin cancer can be treated in the early stages of formation. Basal cell cancer is one of the most common types of skin cancer, this cancer may also happen on the sun exposed skin and on the face (Egan 10).Squamous cells are the second most common form of skin cancer. Squamous cells form on sun exposed skin (Egan 11). For example, it could potentially form on the shoulders, neck, or hands (Egan 10-11). Each stage of skin cancer may vary depending on the person.

Often times , most people do not think twice about the dangers of skin cancer . The leading cause of skin cancer is too much exposure to the sun. Skin cancer can be prevented , as well as treatable with the help of suns

Some causes of skin cancer are over explosion to UV light, moles, as well it can be passed on hereditarily.

Now that we know different types of skin cancer, it is important to know the causes for this disease. The first one is the environmental pollutants that we are exposed to such as coal, tar, and radium. Exposure to ionizing radiation such as x-rays also cause skin cancer (“Theoretical Causes”, 2000, P.6).

These brown coloured cancerous growths develop when unrepaired DNA has committed damage to the body’s skin cells. It is known that it is the most commonly triggered by vigorous amounts of sunshine, over excessive use of tanning bed and UV lights which result in making mutations in the skin that produces the skin cells to over multiply at a quick rate which can eventually form nasty tumours.

Most skin cancers occur as the result of damage or malformation to the DNA within the cells of the epidermis. DNA instructs the cells as to how to reproduce, and in the event that the DNA becomes compromised the oncogenes, which control the growth and survival of cells, may become disrupted. When this occurs, tumor suppressor genes, which slow down cell growth, can be shut off. This will cause new cells to grow rapidly and old cells will not be destroyed. The result will be the formation of a mass or tumor.

United States. Skin cancer has been the most popular form of cancer that is growing especially since the invention of tanning beds. Sun exposure and radiation exposure increase the risk of skin cancer. The definition of cancer is abnormal cell growth or behavior. Studies have shown that sun and radiation exposure damage the cells in your body. Richard Wagman is the author of this article; he is a doctor who specializes in internal medicine. The publication is from The New Complete Medical and Health Encyclopedia, which is a book written by M.D. Richard

Cancer is characterized by unregulated/uncontrolled growth and spread of abnormal cells. The etiological factors of Cancer include both external factors (tobacco, infectious organisms, chemicals, and radiation) and inherent factors (inherited mutations, hormones, immune conditions, and mutations that occur from metabolism). The etiological factors may act together or in sequence to trigger the development of cancer. It may take several years for the manifestation of the disease to be obvious after the initial trigger.

It is believed that the amount of exposure of the skin to the sun before the age of 20 is actually the determining risk factor for melanoma. Basal cell carcinoma is the most common skin cancer and tends to only spread locally. Squamous cell carcinoma is the second most common skin cancer, and it can spread to other parts of the body, although not as commonly as melanoma. The risk of getting basal cell carcinoma or squamous cell carcinoma is determined by a person 's lifetime exposure to UV radiation and the person 's pigment protection.

Skin cells that lose the ability to grow and divide are called skin cancer. Another name for skin cancer is neoplasia. Skin cancer begins on the outer layer of the skin called the epidermis and is the most common form of cancer in humans. All skin cancers are important but the most commonly seem is the basal cell carcinoma, squamous cell carcinoma, melanoma. These skin cancers happens when the skin starts to grows abnormal skin cells and form a mass called a skin tumor. Basal cell carcinoma and squamous are the most common skin cancer and they are referred to as nonmelanoma cancer. The least dangerous skin cancer of the three is the basal cell carcinoma. The most dangerous skin cancer of the three is melanoma because it spreads quickly to

Skin Cancer is the abnormal division of skin cells which cause tumors in the body. There are 3 types of Skin Cancer: Melanoma, Basal cell carcinoma, and squamous cell carcinoma (Web Md, year). Skin cancer is caused by the exposure of ultraviolet radiation and UV-like factors (Skin Cancer Foundation, 2015). This paper focuses on a specific type of skin cancer called Melanoma.

1. Light-colored skin and a history of sun exposure is the main cause of this type of cancer. Men are affected more often than women.

The scariest fact found when researching the effects of exposure to the sun’s harmful rays is that ninety present of skin cancer is caused by it. Doesn’t knowing the facts make you want to shield yourself and your children by never going outside again? Unfortunately, that is just imposable but educating our youth is the first step to prevention since most sun exposure is achieved before the age of eighteen. According to the American Academy of Dermatology, one out of every five American’s will develop skin cancer. The three main types of skin cancer are basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and malignant melanoma. Basal cell carcinoma (BCC) is the most common
