How can you tell the difference between atypical moles and melanoma?

Atypical moles are often larger than other nevi (> 6 mm diameter) and primarily round (unlike many melanomas) but with indistinct borders and mild asymmetry. In contrast, melanomas have greater irregularity of color and may have areas that are red, blue, whitish, or depigmented with a scarred appearance.

Can atypical moles be benign?

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.

Should a moderately atypical mole be removed?

Can you have melanoma for years and not know?

How long can you have melanoma and not know it? It depends on the type of melanoma.

Like a cavity, a melanoma may grow for years before producing any significant symptoms.

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.

How do you know if melanoma has spread?

For people with more-advanced melanomas, doctors may recommend imaging tests to look for signs that the cancer has spread to other areas of the body. Imaging tests may include X-rays, CT scans and positron emission tomography (PET) scans.

What percentage of biopsied moles are melanoma?
