What are moles?

Moles, also known as nevi, are small skin formations that can vary in color from light pink to black. They form when the skin's pigment cells, melanocytes, cluster together. Most people have moles, and they can appear anywhere on the body.

How are moles assessed?

Doctors assess moles based on their appearance, size, shape, and color. A method called the "ABCDE rule" is often used, where one looks for Asymmetry, Border, Color, Diameter, and Evolution (changes over time). If a mole shows signs of these changes, it should be examined more closely.

Why are moles removed?

Although most moles are harmless, some may be signs of melanoma, a type of skin cancer. If a mole is suspicious, a doctor may choose to remove it to prevent possible cancer development or to analyze it under a microscope.

Procedures for removing moles

There are several methods for removing moles, including cutting, scraping, the freezing method, and laser treatment. The choice of method depends on the size, location, and shape of the mole.

Aftercare and care

After removing a mole, it is important to follow the doctor's instructions to avoid infection and promote healing. This may include cleaning the area, applying antibacterial ointment, and protecting it from sunlight.

How do I book an appointment with the doctor?

If you are concerned about a mole or want to have it removed, the first step is to book an appointment with your doctor. Many doctors offer online booking, or you can call the clinic directly. It is always better to be on the safe side, so don't hesitate to seek professional assessment.

Frequently asked questions about moles

How can I tell the difference between a normal mole and a suspicious mole?

A normal mole is often uniform in color, round or oval, and does not change over time. Suspicious moles may be asymmetrical, have irregular edges, vary in color, be larger than 6mm in diameter, or change over time.

Are all dark moles a sign of cancer?

No, many dark moles are completely normal. But if you notice sudden changes in a mole or have a mole that looks different from your others, you should consult a doctor.

Can moles come back after removal?

It is rare, but sometimes some cells from the mole can remain and cause regeneration of the mole. If this happens, or if the new mole looks different, you should contact your doctor.

How long does it take for a removed mole to heal?

The healing process depends on the removal method and the individual's overall health. Typically, minor procedures may take 1-2 weeks, while major procedures may take longer. Always follow the doctor's advice on aftercare.
