Skin cancer primarily develops on areas that are exposed to the sun, including the scalp, lips, face, neck, ears, chest, arms, hands and legs in men and women.
Skin Cancer Signs and Symptoms on arms initially starts as a smooth, small, pale, shiny or waxy lump on the arms or it can even look like a firm red lump. Skin cancers are of various type e.g. melanoma, basal cell carcinoma and squamous cell carcinoma. Skin Cancer Signs and Symptoms often begin with changes in colour and tune of the arms skin. Then there can be new growths or precancerous lesions. It can affect people of any skin tone, also those with darker skin complexions.
WHO data shows an increased rate of skin cancers, both non-melanoma and melanoma. There are 3 million non-melanoma skin cancers patients. Melanoma skin cancer affects 132,000 persons each year, worldwide. Skin Cancer Foundation Statistics reveals that one in every five person in United States is at risk of developing skin cancer.
As ozone levels are depleted, the atmosphere loses more and more of its protective filter function and more solar UV radiation reaches the Earth's surface. It is estimated that a 10 per cent decrease in ozone levels will result in an additional 300,000 non-melanoma and 4,500 melanoma skin cancer cases. The global incidence of melanoma continues to increase – however, the main factors that predispose to the development of melanoma seem to be connected with recreational exposure to the sun and a history of sunburn. These factors lie within each individual's own responsibility.
