The sun is an amazing creation, it gives off vitamin C while making people feel warm and happy. In addition to trying to achieve that beautiful tan there are many reasons why people love to bath in the sun but plenty more reasons on why people should protect themselves from the sun. Overexposure to the sun could cause severe permanent damage to the skin, including premature aging and the worst of all skin cancer. The sun releases UV rays (ultraviolet radiation) which damages DNA and disables protective tumor suppressor genes in the epidermal cells, causing the skin cells to rapidly multiply forming tumors.
Skin cancer is an abnormal growth of cells, and there are three main types of skin cancer. Squamous cell carcinoma, basal cell carcinoma and lastly malignant melanoma, the one that we are going to focus on. While it is not the most common type of skin cancer, that is basal cell carcinoma, it is the most dangerous/deadly.
Although there are several types of skin cancer, the most aggressive form is melanoma. This cancer of the skin involves mass replication of the pigment producing melanocyte cells, which are located in the epidermis, below the basal layer. There are several factors involved with the onset of melanoma including, exposure to ultraviolet rays, genetic predisposition, numerous nevi (moles), immunosuppression, and environmental exposure to carcinogens.
“Skin cancers are the most prevalent form of cancer in the Unites States An estimated 11,790 people die of skin cancer each year, 8700 from malignant melanoma” (Huether, McCance, 2012, p. 1058). Since melanoma is the most prevalent form of cancer, it is important to understand what causes it, what it does, who is at a higher risk, and possible treatment routes.
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
There are three primary layers of the skin: the outer layer, the epidermis and the layer beneath, the dermis and the hypodermis. The epidermis is thin, tough and waterproof while protecting the body from outside bacteria invading the body. It also contains keratinocytes which are from the basal layer which is the deepest layer of the skin. The keratinocytes reach up to the epidermis, shed and new ones form again. The dermis is the second layer of the skin and is the thickest. It is made from fibrous and elastic tissues which are made from fibrillin, elastin and collagen to create the strength and flexibility. It also contains sweat and oil glands, nerve endings, blood vessels and hair follicles. Sweat glands help the body cool off during heat
Melanoma is the most dangerous type of skin cancer, it is less common but more serious. In 2012, there was an estimated 996,587 people living with melanoma. In 2015 there were 9,940 deaths with melanoma being the cause. Australia and New Zealand have the highest rates of melanoma in the world. This type of cancer is more common in men than woman. This cancer develops from pigment-containing melanocytes. The majority of melanoma is black or brown and can include skin toned, pink, red, purple, blue, or white. Skin cancer begins in the epidermis which is made up of squamous cells, basal cells, and melanocytes. Melanoma is the disease in which cancer cells form from the melanocytes. It can occur anywhere on the skin, and include a change in the way a mole or
Skin cancer is the most common out of all cancers. About 3.5 million cases are basal and squamous cells. Melanoma a more dangerous skin cancer had 73,000 cases in 2015.The most common types of skin cancer are basal, melanoma and squamous cell skin carcinoma. Basal a type of skin cancer that begins in the basal cells. Melanoma the most serious type of skin cancer. Squamous cell skin carcinoma a form of skin cancer that develops in the cells of the outer layer of the skin. Skin cancer begins in the cells that make up the epidermis. When the DNA that controls the cells growth is damaged, it causes an overgrowth and build up of skin cells. Eventually, this skin cell buildup forms a tumor, which results in the symptoms you see. Some causes of skin cancer are sun, solar radiation, ultraviolet tanning
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.
Melanoma is the most dangerous kind of skin cancer. the most common type is cutaneous melanoma the development of this disease is presented in the melanocytes. The cause of melanoma is not scientifically discovered but excessive exposure to ultraviolet radiation may increase the risk of getting skin cancer.
According to the Skin Cancer Foundation, one in five Americans will develop skin cancer in the course of a lifetime. Consider that 90% of nonmelanoma skin cancers are associated with high exposure to UV radiation from the sun (which means 90% of nonmelanoma skin cancers are preventable!) WebMD reports that Melanoma ( a severe type of skin cancer) often starts as a change in skin or a mole growth.
Skin cancer is a very common form of cancer in Australia. People are exposed to ultraviolet radiation more extensively than anywhere else in the world. Cancer is a disease in which cells grow and divide aggressively. These cells invade and destroy other tissues and sometimes spread to other areas in the body.
A. Do you know that skin cancer is the most common type of cancer in the United States; two million people are diagnosed annually.
The article “Melanoma: Causes, Symptoms, and Treatments” written by Markus MacGill and reviewed by Dr. Helen Webberley is exactly what it states, an article on the integumentary disease melanoma. This article tells everything about melanoma, stating that it is a very deadly type of skin cancer. It is fortunate that it is the least common, however it is still responsible for the majority of skin cancer related deaths each year. Melanoma comes from pigment-producing cells that have mutated into a cancerous cell. They spread quickly, almost too quickly to catch. Skin cancer is first noticed by the look of the skin, then can be confirmed or denied with testing. Melanoma may not produce symptoms. Staying out of the sun for extended amounts of time is best when avoiding skin problems, especially skin cancer. Melanoma is seen mostly in people over the age of forty, and favors women. It can develop anywhere on the skin but does favor the trunk of men and the legs of women. Melanoma will form changes in existing moles on the skin. People should be checking for noticeable differences in skin constantly, especially those who have a known risk. Some early indicators of melanoma could be pale skin, light eyes, numerous moles, multiple freckles, sun exposure, light hair, age, and a few more. Sadly, most these are unavoidable.
treatments: Medicines (creams), Medicines that you take by mouth, A treatment using ultraviolet A (UVA) light (PUVA) and extracting the infected area surgically.
