These moles are not cancerous, and need not be removed if they are not changing. Instead, atypical moles can be a sign of an increased risk for melanoma skin cancer. Therefore, people with atypical moles are recommended to have regular skin checks with a doctor.
What percentage of atypical moles are cancerous?
These moles aren’t cancerous, but they can turn into cancer. About 1 out of every 10 Americans has at least one atypical mole. The more of these moles you have, the greater your risk of developing melanoma — the deadliest type of skin cancer. Having 10 or more atypical moles increases your risk 14-fold.
Are all atypical moles precancerous?
Since severely atypical nevi and early melanomas may be indistinguishable on clinical exam, no one wants to leave such a lesion unbiopsied. Having said that, it is somewhat of an overdiagnosis to equate lesions that are diagnosed as mildly or moderately atypical by a pathologist as definitely precancerous.
Can atypical moles be benign?
Atypical moles are benign pigmented lesions. Although they are benign, they exhibit some of the clinical and histologic features of malignant melanoma. They are more common in fair-skinned individuals and in those with high sun exposure.
Why are atypical moles removed?
Although atypical moles are benign (non-cancerous), their presence is linked to an increased risk of melanoma (the most serious form of skin cancer). People with 10 or more atypical moles have 12x the risk of developing melanoma. Atypical moles resemble melanoma, which is why mole removal is so critical.
How can you tell the difference between atypical moles and melanoma?
Like dysplastic nevi, melanoma presents itself as an asymmetrical, multicolored growth with an irregular border.
Some other characteristics of atypical moles are:
- Larger than average moles.
- The surface can be bumpy or smooth.
- Can have a raised darker center surrounded by a flat, lighter area.

What does early stage melanoma look like?
The first sign of melanoma is typically a new spot on the skin, or a change in the size, shape or color of an existing mole. The ABCDE method may help you determine whether an abnormal skin growth may be melanoma: Asymmetry: The mole has an irregular shape. Border: The edge is not smooth, but irregular or notched.
Is it normal to have atypical moles?
Atypical moles, also called dysplastic moles, are very common. An estimated one out of every 10 Americans has at least one atypical mole. These moles are larger than common moles, with borders that are irregular and poorly defined.
Are atypical moles bad?
Atypical moles, also known as dysplastic nevi, are unusual-looking moles that have irregular features under the microscope. Though benign, they are worth more of your attention because individuals with atypical moles are at increased risk for melanoma, a dangerous skin cancer.
Do atypical moles change over time?
Most types of atypical moles remain stable over time. Patients with five or more dysplastic nevi are 10 times more likely to develop melanoma than individuals with no atypical moles. The greater the number of dysplastic nevi on the body, the more likely the development of melanoma.
How long does it take for melanoma to spread?
Melanoma can grow very quickly. It can become life-threatening in as little as six weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.
What percent of atypical moles become melanoma?
Atypical moles and melanoma risk
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.
What is atypical mole syndrome?
Atypical mole syndrome (AMS), also known as dysplastic nevi syndrome (DNS), B-K mole syndrome, Clark nevi syndrome, or familial atypical multiple mole melanoma (FAMMM) syndrome, is a condition characterized by a large number of pigmented nevi with architectural disorder, which arise sporadically or by inheritance and …
Can a removed mole grow back?
If a common mole is removed completely, it should not grow back. However, some Conroe residents may experience the regrowth of a mole if some of the mole cells were left behind after the mole removal procedure. But a mole that grows back does not mean it is cancerous. To avoid regrowth, be sure to talk to Dr.
Should I have dysplastic nevi removed?
Should people have a doctor remove a dysplastic nevus or a common mole to prevent it from changing into melanoma? No. Normally, people do not need to have a dysplastic nevus or common mole removed. One reason is that very few dysplastic nevi or common moles turn into melanoma (1, 3).
Are all moles removed biopsied?
Lab testing showed that more than 90 percent of biopsied moles were completely removed by using the single procedure, with 11 (7 percent) diagnosed as melanoma, one of the most aggressive forms of skin cancer.
