Types of Moles

- Common moles: These are usually smaller than a pencil eraser and have a uniform color and shape.
- Atypical moles (dysplastic nevi): These moles may be larger than common moles and have irregular shapes, borders, and coloration.They may be more likely to develop into melanoma, a type of skin cancer.

Overview
Moles, medically known as nevi, are common skin growths that can appear anywhere on your body. They usually appear in childhood and evolve over time, becoming raised or changing color. Some may even disappear over time. Although most moles are harmless, they can sometimes become cancerous. In such cases, mole removal may be recommended.
Symptoms
Moles come in a wide variety of colors, sizes, and shapes. They can be brown, black, tan, red, pink, blue, or skin-colored and can be flat or raised. They can be round or oval and can be as small as a pinhead or large enough to cover an entire limb. Changes in a mole’s color, size, or feel, or the onset of symptoms such as itching, tenderness, or bleeding, could be indicators of skin cancer and should prompt an evaluation. Mole removal might be necessary in such cases.
Causes
Moles are caused when cells in the skin, known as melanocytes, grow in clusters instead of being spread throughout the skin. These cells produce the pigment that gives skin its natural color. Sun exposure, particularly in childhood, may influence the number of moles that develop. Some people have a genetic predisposition to moles, having inherited a tendency to have more moles from their parents.
Myths
One of the common myths is that all moles are cancerous, which is not true. Most moles are harmless and do not require removal. However, if a mole changes size, color, or shape, it could be a sign of a type of skin cancer called melanoma, necessitating mole removal. Another myth is that mole removal always leaves a significant scar. The reality is, while any procedure can potentially leave a scar, a skilled dermatologist can often minimize scarring through careful technique.
Treatment
The primary treatment for a suspicious mole, or one that is bothersome for other reasons, is mole removal. There are a few different methods for mole removal. Surgical excision involves numbing the area around the mole and cutting out the mole and a margin of healthy skin around it. The wound is then stitched closed.
In surgical shave, the area around the mole is numbed, and the mole is cut off with a small, sharp scalpel. This method doesn’t require stitches and is often used for smaller moles. The method used often depends on the mole’s size, location, and whether it’s suspected to be cancerous.
Mole removal is generally a safe, straightforward procedure. However, as with any procedure, there can be risks and side effects, such as infection, nerve damage, or an allergic reaction to the anesthetic. There’s also a chance that the mole can recur after removal, although this is relatively rare.
After mole removal, it’s crucial to keep the area clean and to apply an antibiotic ointment regularly to prevent infection. You should also avoid sun exposure as it can cause the scar to darken.
In conclusion, while moles are usually harmless and often don’t require treatment, it’s essential to keep an eye on them and report any changes to a healthcare professional. Mole removal can be a straightforward and safe procedure and can be crucial in preventing the spread of skin cancer if a mole is found to be cancerous.
