Skin Cancer
Skin cancers (neoplasms) are named after the type of skin cell from which they arise. Basal cell cancer originates from the lowest layer of the epidermis, and is the most common but least dangerous skin cancer. Squamous cell cancer originates from the middle layer, and is less common but more likely to spread and, if untreated, become fatal. Melanoma, which originates in the pigment-producing cells (melanocytes), is the least common, but most aggressive, most likely to spread and, if untreated, become fatal. Still, melanoma has one of the higher survival rates among major cancer, with over 75% of patients surviving 10 years in the UK during 2005-2007.
In the UK in 2010, 12,818 people were diagnosed with malignant melanoma, and about 100,000 people were diagnosed with non-melanoma skin cancer. There were 2,746 deaths from skin cancer, 2,203 from malignant melanoma and 546 from non-malignant melanoma. In the US in 2008, 59,695 people were diagnosed with melanomaa, and 8,623 people died from it.
Most cases are caused by over-exposure to UV rays from the sun or sunbeds.

Famous quotes containing the words skin and/or cancer:
“Racism as a form of skin worship, and as a sickness and a pathological anxiety for America, is so great, until the poor whites—rather than fighting for jobs or education—fight to remain pink and fight to remain white. And therefore they cannot see an alliance with people that they feel to be inherently inferior.”
—Jesse Jackson (b. 1941)
“Ever since I was a kid my folks fed me bigotry for breakfast and ignorance for supper. Never, not once did they ever make me feel proud of where I was born. That’s it. That was a cancer they put in me. No knowledge of my country. No pride. Just a hymn of hate.”
—Samuel Fuller (b. 1911)
