What Causes Dark Moles?

Dark moles can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose dark moles, we could:

Research the topic
Find a doctor with the time
Use a diagnostic computer system.

The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "dark moles" as a symptom. For example, melanoma.

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:

dark lines under nails

black/brown fingernails

history of melanoma

significant mouth sores

light hair

light eye color

having many common moles

melanoma

bleeding/enlarging/tender moles

melanoma in family members

lighter/paler skin color

... and so on

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of dark moles.

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Existing Skin Conditions section of the questionnaire, The Analyst™ will ask the following question about irregular dark moles:

Do you have any dark moles with a rough/irregular shape and varied color? These are different from normal moles.

Possible responses:

→ No / only normal moles / don't know
→ Yes, under 5 irregular dark moles
→ Yes, about 5 to 20 irregular dark moles
→ Yes, more than 20 irregular dark moles

Based on your response to this question, which may indicate irregular dark moles, many irregular dark moles or very many irregular dark moles, The Analyst™ will consider possibilities such as Melanoma. A person who has more than 5 atypical or "dysplastic" moles has a higher risk of developing melanoma and should check their skin thoroughly several times per year to look for changes.
