Most individuals with moles are born with them, though they might not appear until later in life. Moles are caused by skin cells called melanocytes which can grow in clumps or clusters. These clusters have skin tissue surrounding them, which on the outside of the skin, look like moles. They are different then freckles and often raised from the skin, different colors, different shapes and sizes and look different from ordinary skin freckles. If you have had moles since you were young but they suddenly begin looking darker, it might be from a change in hormones during pregnancy or while you is a teenager or could be due to exposure to the sun. This isnt usually an issue unless they look oddly colors, more than one color, have a ring around them or begin changing their shape.
There are specific signs to look for and determine whether or not you have moles; they will be round in shape, look the same each month, be flat or raised and be one color. Colors include black, tan, skin-toned, pink, red, blue or have no color at all. These are signs of a normal mole and distinguish them from freckles. Each mole might not look like the next if you have more than one on your body, but thats fine as long as the mole doesnt change in color, shape or texture. Signs of potentially cancerous moles (melanoma) will be more than one color, irregularly shaped or have a bumpy texture.
You should also be concerned about brand new moles that simply appear one day. Diagnosing moles will always start with a physical examination to look at the moles on your skin; this is done to find out if they might look cancerous. Your doctor may perform tests such as a skin biopsy to find out if it is malignant. If you have moles n your skin that cause pain, have rings around them, are bleeding or oozing fluid, itching, burning, not rounded or change in their texture, size, shape or color, get it looked at by a dermatologist right away.
The best treatment is an examination by a medical professional. This is to ensure the moles are not cancerous or will cause any harm to you. Ultimately, many moles dont require treatment if they are determined to not be cancerous, though some individuals choose to get them surgically removed. This is usually for cosmetic reasons or because the location causes it to rub against clothing and it becomes uncomfortable or snags often. Your moles can be removed during a single or second office visit with a minor procedure. Common surgical procedures to remove moles include a surgical excision to cut out the mole and some of the surrounding tissue with a scalpel or a surgical shave which uses a blade to remove the mole. You should never try to remove a mole on your own, whether from shaving or otherwise. Not only is it dangerous, but moles can grow back if they are not removed in the right way.
