Can atypical moles change?

Some atypical (as well as common) moles can change into melanoma, but most atypical moles will never change to cancer. In fact, melanoma is more likely to develop as a new, unusual spot on normal skin, unrelated to moles.

Can atypical moles change over time?

These lesions will change over time(37), but most changes are not worrisome for melanoma. The majority of dysplastic nevi undergo involution over years. As previously mentioned, lesions should only be biopsied when changing in a manner suspicious for melanoma.

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.

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.

Can you have just one atypical mole?

People without a family history of atypical moles or melanoma have an increased risk of melanoma, but it is not as high as the risk observed in members of melanoma-prone families. Individuals with a single atypical mole on their bodies have a twofold risk of developing melanoma.

Should an atypical mole be removed?

Atypical moles should be removed when they have features suggestive of malignant transformation. Elliptical excision is the preferred removal technique. Removing all atypical moles is neither necessary nor cost effective.

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.

What percentage of atypical moles are melanoma?

Less common are atypical moles (dysplastic nevi). 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.

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.

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 Melanoma go undetected for years?

How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.

How long does melanoma take 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.

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.

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).
