Skin cancer, otherwise known as skin melanoma, has become a serious epidemic in the United States over the last several years. Approximately one in 60 people will develop some form of skin cancer in their life time. With tanning beds and extended outdoor tanning becoming more common, as well as “being tan” become the new beauty tip. However, genetics still plays a very important role in skin cancer. It has been said that people with minimal eumelanin genes, the gene that determines hair and eye color, are more susceptible to skin cancer to do their light hair, eyes and fair skin. Most skin cancer cases are caused by ultraviolet rays, however, approximately five percent of cases are…

People are now seeing the truth, but even if they know what's happening to them it's important to know the reasons it's happening . To get down to basics there are five clinical types of melanoma. The most common form is called the superficial spreading melanoma and it about 70% of all melanoma cases. It is commonly found on the truck in men and on the legs in woman (Joan 4). Many people get confused on what melanoma is. Melanoma is a tumor of melanin-forming cells, melanin cells are cells that have turned dark brown by the overexposure of sun. Basal and squamous are a less deadly form of skin cancer also caused by the overexposure of sun. It's important for us to know why skin cancers specifically the more deadly ones like melanoma are spreading and the answer is very clear. While basal and squamous cell cancers tend to invade locally, melanoma spreads very quickly to other parts of the body ( Egan 6). The unfortunate part is that people today are finally getting the information they need. In the past people didn't know that sun burns and not wearing sunscreen could affect them so much in the future. Between 40 and 50 percent of Americans who live to age 65 will have either basal cell carcinoma or squamous cell carcinoma at least once ( Steve 6). Although the number is still increasing with more awareness it can be easy to…
As I began to explore more in depth about this topic, nothing really seemed to sway me away from the tanning beds until I came upon these statistics from the Skin Cancer Foundation stating that “Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung and colon.” When UVR was proven a human carcinogen it was a huge step; this had always been an idea but when it was a fact it opened the eyes to many tanning bed users.…

UVA rays may make you tan, but they can also cause serious damage. That's because UVA rays penetrate deeper into the skin than UVB rays. UVA rays can go all the way through the skin's protective epidermis to the dermis, where blood vessels and nerves are found. Because of this, UVA rays may damage a person's immune system, making it harder to fight off diseases and leading to illnesses like melanoma, the most serious (and deadly) type of skin cancer.…
The use of sun protection has become a much more common topic of conversation among the general population over the last decade. This can be attributed to several different factors. In some instances, environmental concerns over depleting ozone and higher levels of radiation penetration are the cause. Another important reason is that well over half of all new cancers in the United States are skin cancers (Capelle, 2006, pg. 1). Ultra-violet (UV) light is the cause of these cancers. There are several types of UV light. According to Gonzaga sunlight is made up of a broad spectrum of light. This spectrum is divided by wavelength in UV light. There are three types of UV light; UVA, UVB, and UVC (Gonzaga, 2009, 19). UVC is almost completely absorbed by the ozone. UVA and UVB are the two types of UV light that penetrate and affect people. UVA penetrates deeper into the skin and can cause immediate darkening of pigments, there is increasing thought that UVA may have more to do with photodamage than thought previously (Gonzaga, 2009, 21). UVB light ranges from 290 mm to 320 mm and is carcinogenic. It does not penetrate as deeply into the skin as UVA, however it has several acute effects including…

Skin cancer occurs when a person is exposed to ultraviolet light, weather that is from the sun or fake ultraviolet rays. Whether you tan outside or indoors, you can get skin cancer in both scenarios. Skin cancer comes in several forms,…
Almost 25 percent of adolescents in America have reported going to an indoor tanning salon. Prevention and awareness are the two best ways to stop the increasing rise of skin cancer. It is necessary to be safe when exposing yourself to the sun. Proper eye protection should always be worn, such as sunglasses that cover 100 percent of UVA and UVB rays. But most importantly, a sunscreen with at least SPF 30 should always be worn when there is any chance to exposure from the sun. Along with regularly performed examinations of moles and spots on the skin, skin cancer can be nearly 100 percent treatable at an early…
The skin is surprisingly tough given its thinness. That being said, it can be damaged by exposure to sunlight. This often presents in the form of skin cancer. There are three types of skin cancer - basal cell carcinoma, squamous cell carcinoma and melanoma. Squamous occurs in the top level of the skin, basal cell in the middle layer…

Cancer arises in part through damage to normal genes (known as “proto-oncogenes”), which can arise from exposures to cancer-promoting agents, such as UV light. That damage permanently switches the gene on, transforming it into an oncogene that helps push cells to become cancerous.…
