Mole screening, also known as dermoscopy or dermatoscopy, is a non-invasive procedure that dermatologists use to examine moles and other pigmented skin lesions. It involves using a magnifying device called a dermatoscope to closely inspect the moles, looking for any signs of changes that could indicate melanoma, the most serious type of skin cancer.

​

Why is Mole Screening Important?

​

Early detection of melanoma is crucial for successful treatment. Melanoma is typically treatable if it is diagnosed at an early stage, but it becomes more difficult to treat as it grows larger and spreads. Mole screening is an important tool for early detection, as it can help identify moles that may be at risk of developing into melanoma.

​

Who Needs Mole Screening?

​

Anyone with a history of skin cancer, a family history of melanoma, or many moles is at an increased risk of developing melanoma. These individuals may benefit from more frequent mole screening than people with no known risk factors.

​

How is Mole Screening Performed?

​

During a mole screening appointment, the dermatologist will examine your entire body, including your scalp, ears, palms, soles of your feet, and underarms. They will use a dermatoscope to magnify the moles and look for any signs of changes, such as:

• Asymmetry: One half of the mole is different from the other half.

• Border irregularity: The edges of the mole are not smooth or well-defined.

• Color variation: The color of the mole is uneven or has multiple shades of brown, black, or tan.

• Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser).

• Elevation: The mole is raised above the skin surface.

​

What Happens if Abnormal Changes are Found?

​

If the dermatologist finds any abnormal changes in a mole, they may recommend a biopsy to remove a small sample of the mole for further testing. A biopsy can help determine if a mole is benign (non-cancerous) or malignant (cancerous).

​

How Often Should I Get Mole Screening?

​

The frequency of mole screening depends on your individual risk factors. People with a high risk of melanoma may need to be screened every 3-6 months, while those with a lower risk may only need to be screened every 1-2 years.

​

What Can I Do to Reduce My Risk of Melanoma?

​

In addition to mole screening, there are several things you can do to reduce your risk of melanoma:

• Avoid excessive sun exposure. The sun's ultraviolet (UV) rays are the primary cause of skin cancer.

• Wear protective clothing, including a wide-brimmed hat, sunglasses, and long sleeves and pants, when you are outdoors.

• Apply a broad-spectrum sunscreen with an SPF of 30 or higher to all exposed skin 15 minutes before going outdoors and reapply every two hours, or more often if you are sweating or swimming.

• Limit your exposure to tanning beds. Tanning beds emit UVA rays, which are just as harmful as UVB rays from the sun.
