How do dermatologists tell whether a spot is a mole?
A dermatologist’s trained eye can often tell whether a spot is a mole.
How do dermatologists treat moles?
Most moles do not require treatment. A dermatologist will remove a mole that:
- Bothers a patient (rubs against clothing, etc.).
- A patient finds unattractive.
- Could be skin cancer.
A dermatologist can remove a mole during an office visit. A few moles will require a second visit. Whether it's during 1 or 2 visits, a dermatologist can safely and easily remove a mole. A dermatologist will use 1 of these procedures:
- Surgical excision: The dermatologist cuts out the entire mole and stitches the skin closed. If the dermatologist suspects that the mole contains cancer, the dermatologist will send the mole to a lab. It will be examined under a microscope. This is called a biopsy.
- Surgical shave: The dermatologist uses a surgical blade to remove the mole.
Never try to shave off a mole at home.
Here’s why you should never try to shave off a mole at home:
- If the mole contains skin cancer, some of the cancer cells can stay in the skin — and even spread.
- You can disfigure your skin, causing a scar or other permanent reminder.
- You can cause an infection.
After a mole is removed, the skin will heal. If the mole grows back, immediately make another appointment to see your dermatologist. This is a sign of melanoma, a type of skin cancer.
