Living with Familial melanoma

An inherited form of melanoma, a skin cancer that starts in pigment-making cells, that runs in families.

Understanding Familial melanoma

Familial melanoma is an inherited form of melanoma, a type of skin cancer that starts in the pigment-making cells (melanocytes).

Melanoma usually occurs on the skin, but in about 5 percent of cases it starts in other tissues such as the eyes or the lining of the mouth. It can develop at any age, most often in people in their fifties to seventies. Having many moles (generally more than 25) is linked to a higher risk.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Melanoma
  • Moles (nevi)
  • Freckling
  • Dry skin
  • Changes in hair
  • Changes in the lymphatic system

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include cancer specialists, genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    The Skin Cancer Foundation may keep lists of experts for this condition.
