The ABCDEs of skin cancer are:Asymmetry. One half doesn't match the appearance of the other half.Border irregularity. The edges are ragged, notched, or blurred.Color. The color (pigmentation) is not uniform. Shades of tan, brown, and black are present. Dashes of red, white, and blue add to a mottled appearance.Diameter. The size of the mole is greater than 1/4 inch (6 mm), about the size of a pencil eraser. Any growth of a mole should be evaluated.Evolution. There is a change in the size, shape, symptoms (such as itching or tenderness), surface (especially bleeding), or color of a mole.If any of these describe your moles, you should have them removed and examined by a pathologist. If not, there is no hurry unless you just don't like the way it looks. If you were my patient, I would recommend an elliptical excision. Best of luck!
