Melanoma Skin Cancer
Melanoma skin cancer is the most dangerous of all skin cancers. It develops in damaged DNA and mutates into rapidly forming tumors. If melanoma is recognized and treated, then the chances of spreading can be avoided. When the symptoms are found and treated then it is usually curable. The skin that has been burnt in the past by sun will be transformed into cancer cells after many years. 90% of the melanoma is a result of increased exposure to ultra violet rays.
Melanoma skin cancer arises from a specific cell type, melanocytes, in the skin. Melanocytes are the cells that give color to our skin; therefore, these cancers typically arise as pigmented (colored) lesions. Early staged melanoma is often referred to as "melanoma in situ" or "lentigomaligna".
Melanoma can occur in the melanocytes anywhere throughout the body. The skin that has not been exposed to sun can also develop melanoma if the family members have a history of cancer or due to environmental factors. Melanoma is easy to detect because it is often seen in the skin which makes detection earlier easier. The symptoms are usually a change on the skin that has a new spot. A sore that bleeds and doesn’t heal or a change in the size, shape of the mole should warrant a biopsy. It is important to note that all moles don’t turn into melanoma.
