The risk of an atypical mole becoming cancerous is about 1%, compared to . 03% for an ordinary mole. In addition to atypical moles, risk factors for developing melanoma include: Red or blond hair.
What percent of atypical moles become melanoma?
One study found that the risk of an atypical mole turning into melanoma over an individual’s lifetime is less than 0.1% for both men and women.
Should atypical moles be biopsied?
D (Diameter): If an atypical mole grows to the size of a pencil eraser (approximately 6 mm, or ¼ inch in diameter), this is a sign that the mole is cancerous. It’s important to have moles removed and biopsied before they grow larger and lead to other potential complications.

In a case-control study of 287 white patients with atypical mole syndrome followed for an average of 88 months, 10 patients (3.5 percent) developed melanoma. In contrast, of the 831 control patients without atypical mole syndrome, only two (0.2 percent) developed melanoma.
Should all atypical moles be biopsied?
Your doctor may perform a biopsy on a suspect spot. Under the microscope, atypical moles can have unusual features that are graded as mild, moderate, or severe. If the biopsy shows a mildly or moderately atypical mole, and it has been removed fully, no further treatment is needed.
What percentage of severely atypical moles are melanoma?
Lifetime melanoma risk to individuals in the United States is less than 1% but is significantly greater in those with atypical moles, considered to be greater than 10%.
What is melanocytic nevus and how to treat it?
Melanocytic nevi are benign neoplasms or hamartomas composed of melanocytes, the pigment-producing cells that constitutively colonize the epidermis. Melanocytes are derived from the neural crest and migrate during embryogenesis to selected ectodermal sites (primarily the skin and the CNS), but also to the eyes and the ears.
Is a nevus going to develop into skin cancer?
Dysplastic nevi are more likely than normal moles to develop into a type of skin cancer called melanoma. Melanoma can be fatal.
