Other Pigmented Patches on the Skin
If you look closely at your skin, you may notice darkened spots that are not moles. Freckles are the most common of these spots. Unlike moles, they are rarely larger than the size of a pea, although sometimes they may seem to be because they blend into one another. Sun exposure may make freckles darker or freckles may fade completely in the winter. While moles may appear anywhere on the skin, freckles ordinarily are limited to sun exposed areas, such as the face, neck and upper back. Blondes and redheads freckle most easily.
After middle age, a person may acquire other dark areas that are not moles. Brown, wart-like growths that appear on the face or trunk and look as if they have been stuck to the skin may be harmless growths called seborrheic keratoses.
Multiple small gray-brown spots that may appear on wrists, backs of the hands, forearms, and face could be actinic lentigines. These are also called "liver spots" or "age spots," though they have nothing to do with liver or age. They are sunspots. Both actinic lentigines and seborrheic keratoses are easily diagnosed by your dermatologist and are not cancers.
Treatment of Moles
The majority of moles and other blemishes are benign (not-cancer). They will never be a threat to the health of the person who has them. Spots or blemishes that warrant medical concern are those that do something out of the ordinary-those that act differently from other existing moles. This includes any spot that changes in size, shape or color, or one that bleeds, itches, becomes painful, or first appears when a person is past twenty.
Occasionally, a mole may become a cancerous growth. Therefore, it's best to get medical advice if you notice a mole that does not follow the normal pattern. A dermatologist may be able to assure you that the mole is harmless. To accomplish this, he or she may study a sample of it under a microscope for an accurate diagnosis.
The dermatologist will remove the mole, or part of it, so that thin sections from the mole can be cut and examined under a microscope. This is a simple and harmless procedure. If the growth was only partially removed and it is found to be cancerous, then the entire lesion and an extra margin of safety will need to be removed.
A person may wish to get rid of moles that are in areas of trauma, where clothing can irritate them, or simply because they are unattractive. The most common methods of removal include numbing the spot and then shaving the mole off, or for some moles, cutting out the entire lesion and stitching the area closed.
Most procedures used to remove moles take only a short time and can be performed in a dermatologist's office. Sometimes a mole will recur after it is removed. If a removed mole does begin to reappear, the patient should return to see the doctor.
