It is important to know what your moles look like. While moles are harmless, sometimes skin cancer develops in or near a mole. If you know where you have moles and what your moles look like, it can help you find skin cancer early. When found early and treated, skin cancer has a high cure rate.
A mole on your body can be
Moles can differ in size, shape, or color. Moles can have hair. Some moles will change slowly over time, possibly even disappearing.
When talking with your dermatologist about your moles, you may hear the term nevus. Nevus is the medical term for mole. When your dermatologist is talking about 2 or more moles, you may hear nevi.
HOW TO CHECK YOUR MOLES
By getting into the habit of checking your skin, you can learn what your moles look like. Once you know what your moles look like, you’ll be able to spot changes. In adults, a change to a mole or the sudden appearance of a new mole can be a sign of melanoma. Melanoma is a type of skin cancer that can be deadly if not caught early and treated.Finding melanoma early is essential. Melanoma has a cure rate of nearly 100% when found early and properly treated.
The best way to check your skin is to perform a skin self-exam. You can perform this exam at home. You will need a room where you can undress and have access to a full length mirror and a handheld mirror. It also is helpful to use a body mole map to track changes on your skin.
A skin self-exam means you’ll need to look at all of your skin. Moles can appear anywhere on your skin – the scalp, between fingers, on a toe or the sole of the foot. You can even get a mole under your nail.
As you examine your skin, you will look at each individual mole. As you look at a mole, you want to look for the following signs, which you can remember as the ABCDEs.
A stands for ASYMMETRY; one-half does not look like the other half.
B stands for BORDER; irregular, scalloped or poorly defined border.
C stands for COLOR; varied from one spot to another; shades of tan and brown, black; sometimes white, red, or blue.
D DIAMETER; melanomas are most often greater than 6 millimeters (the size of a pencil eraser) when diagnosed, but they can be smaller.
E stands for EVOLVING; a mole or skin growth that looks different from the rest or is changing in size, shape, or color.
WHEN TO SEE A DERMATOLOGIST
As you examine your skin, if you answer yes to any of these questions, you should make an appointment to see a dermatologist immediately. You might have melanoma. When found early, melanoma is highly treatable and has a high cure rate.
REMOVING A MOLE
If your dermatologist sees a mole or other spot that looks abnormal, your dermatologist will recommend removing it.A mole can be removed during an office visit. This is a safe and simple procedure when performed by a dermatologist.
If you have a mole removed, the first step will be to numb the area so that you do not feel pain. Once the area is numb, your dermatologist will surgically remove the mole. Some patients need stitches so to close the wound, but not all.
The skin that your dermatologist removes will be examined under a microscope. Your dermatologist may examine the skin or send it to a lab. Examining the skin under a microscope is the only way to tell whether a patient has skin cancer. This process of removing the skin and examining it under a microscope is called a skin biopsy.
If you see a mole or other spot reappear after a skin biopsy, immediately make an appointment to see your dermatologist.
UNDERSTANDING THE BIOPSY REPORT
The results of your skin biopsy will be described in the biopsy report.
If the biopsy report says your mole is a typical nevus, you do not have skin cancer. An atypical nevus (sometimes referred to as a “dysplastic nevus”) is a mole that does not look like a normal mole but it is not a cancer either. To the naked eye an atypical mole can look like a melanoma. These moles also have a higher risk of progressing to melanoma. You dermatologist will determine if the mole requires any further treatment.

ASK YOUR DERMATOLOGIST
Examining your skin is important. Some people have difficulty doing this because they have so many moles or do not know what to do. If you have any difficulty, you should speak with your dermatologist. Your dermatologist can show you how to examine your skin and provide you with tools that can help you keep track of your moles.
