Are nevus genetic?

This condition is generally not inherited but arises from a mutation in the body’s cells that occurs after conception. This alteration is called a somatic mutation. A somatic mutation in one copy of the NRAS or BRAF gene is sufficient to cause this disorder.

Are nevus hereditary?

Congenital nevi are thought to be caused by a genetic mutation, called a sporadic mutation, which develops randomly as a baby grows in the womb. The condition is not inherited.

What does Stage 1 melanoma look like?

What is the difference between a mole and a nevus?

Nevus (plural: nevi) is the medical term for a mole. Nevi are very common. Most people have between 10 and 40. Common nevi are harmless collections of colored cells.

Is a nevus dangerous?

While most congenital nevi are harmless, they can occasionally become cancerous. Giant congenital nevi carry the highest risk. Keep in mind that surgery isn’t a guarantee against cancer. Fifty percent of melanomas found in people with giant congenital nevi occur elsewhere on the body.

What do cancerous moles look like?

Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders. C is for Color. Multiple colors are a warning sign.
