6. Skin Cancer Skin cancer is the most common cancer in the United States, and continues to rapidly increase.

7. Melanoma Melanoma is the deadliest type of skin cancer. Cancer of melanocytes and is about 5% of cancers. Most appear spontaneously and occur wherever there is color. Will manifest as a mole that has undergone sudden changes in shape, color, or diameter, or suspicious changes such as swelling, scaliness, itching, oozing or bleeding. If left untreated, the tumor can spread downward into deeper skin layers, and to lymph nodes and internal organs.

9. Squamous Cell Carcinoma This condition develops in the epidermis when squamous cells divide abnormally. Squamous cell carcinoma appears as a pink, red or fleshy growth, often with whitish scales on the skin. Areas that receive high levels of exposure to the sun, such as the head, neck and top of the hands, are where squamous cell carcinoma usually develops. Squamous cell is more likely than basal cell carcinoma to spread to lymph nodes and internal organs, though this occurs in only 2 to 3 percent of patients.

11. Basal Cell Carcinoma This cancer develops in the lower layer of the epidermis, called the stratum basal layer. Basal cell carcinoma can appear as a shiny red dome shaped nodules that later turn into ulcers. Basal cell carcinoma is most commonly found on areas of the body that receive significant exposure to the sun, such as the head and neck.

17. Skin and Aging Epidermal replacement of cells slows and skin becomes thinner Skin becomes dry and itchy Subcutaneous fat layer diminishes, leading to intolerance of cold Decreased elasticity and loss of subcutaneous tissue leads to wrinkles Decreased numbers of melanocytes and Langerhans’ cells increase the risk of skin cancer
