The Causes and Symptoms of Skin Cancer
The Causes and symptoms of Skin Cancer While tanning beds and extreme use/exposure to UV rays are ways to get skin cancer, there are also various other ways to get it. Many don’t know that genetics and traits can actually play a huge role in developing this dangerous disease. They also don’t know that skin cancer is the most common type of cancer in the U.S. today. According to the Skin Cancer Foundation more people over the last 300 years have had skin cancer than all of the other cancers combined. They say that one in five people develop skin cancer throughout their lifetime; some surviving, some moribund. Skin cancer starts in the outermost layer of skin called the epidermis. The epidermis

UV radiation plays a huge role in the development of malignant melanoma. This UV radiation can come from a tanning bed, the sun, a sun lamp or even heredity. Recent studies show that if a close blood relative (parent, sibling, uncle aunt, etc.) has or has had the disease before, one is running a greater risk of getting it rather than someone who does not have someone in their family who has had it. To go into further depth, there are four major types of melanoma; superficial spreading melanoma (SSM), which is the most common type. It is usually flat and a blackish-brownish color. Next there is nodular melanoma which starts as a raised lesion and is usually a blackish-bluish or bluish-red color. The second to last type is called lentigo maligna melanoma(LMM). This type usually occurs in older people. LMM is usually large, flat and a tannish color with brown in the center or around it. The last and final type of melanoma is called acral lintiginous melanoma (ALM). This is the least common form. It occurs in the soles, palms, under the fingernails and mostly in African-Americans.
Figure 1 (al., 2012) As shown in figure 1, superficial spreading melanoma has more cases open than nodular, lentigo maligna, and acral lentiginous altogether.
