Moles – Diagnosis and Treatment

Diagnosis

Doctors examine moles and other skin growths by looking at the skin. They use the ABCDE rule to check for signs of skin cancer or melanoma:

• Asymmetry
• Border irregularity
• Color variation
• Diameter greater than 6mm
• Evolving shape or color

If a mole looks suspicious, the doctor may remove it for a biopsy. The doctor studies the sample under a microscope to check for atypical or malignant changes.

Regular skin exams help people find changes early, especially if they have dysplastic nevi or a higher risk of melanoma.

Treatment

Most moles do not need medical care. People who feel embarrassed by a mole can use makeup to cover it.

If a mole has hair, you can trim the hair at the skin’s surface or gently pluck it. Always keep the skin clean, especially after minor cuts or irritation.

If you feel uncomfortable about a mole’s appearance or notice changes, a doctor can remove it surgically. Mole removal is usually quick and done in a clinic.

The doctor numbs the skin and carefully cuts out the mole, sometimes with a small area of healthy skin.

Step	Detail
Numbing	Doctor numbs area around mole
Excision	Doctor cuts out mole, sometimes with margin
Aftercare	Keep area clean; possible scarring

Some people with darker skin might notice color changes or raised scars (keloids) after healing. If a mole grows back or does not heal, see a healthcare provider.

UV radiation and indoor tanning can increase risks. Regular skin checks help spot changes early.

Getting Ready for Your Visit

Steps to Take Before the Appointment

Being prepared makes your skin check with the dermatologist easier and more effective.

Write down any changes in your moles, such as size, color, or shape. Note any new spots, itching, pain, or other symptoms.

Bring a list of all prescription drugs, over-the-counter medicines, vitamins, and supplements. This helps your doctor understand your history.

Share your past skin history, including any mole, melanoma, or spot you have had removed. Note the place and date, and bring any reports you have.

Skip makeup and opaque nail polish before your appointment. This helps the dermatologist see your skin and nails clearly.

Prepare questions to ask, such as:

• Could this mole be skin cancer?
• What do you suggest I do next?
• How can I know if a mole needs to be checked?
• What steps help lower my risk for skin cancer?

Keeping track of these details helps you get the most out of your time with the doctor.

What the Dermatologist May Ask You

During the appointment, the dermatologist or healthcare professional may ask questions to better understand your skin health.

Question	Reason
When did you first see this mole?	To learn how long it’s been there.
Is this mole new or has it always been there?	To check for new growths.
Has the mole changed in color, shape, or size?	These can be signs of risk.
Have you had other moles removed?	Past issues may affect future care.
Do you have a family history of skin cancer or melanoma?	This increases risk.
How much sun exposure have you had?	Sunburns and tanning history matter.

The dermatologist may also ask about your use of tanning beds. They might ask about your sunscreen habits or if you have had sunburns in the past.
