This often leads to a higher risk of melanoma, a serious type of skin cancer. [10] Dysplastic nevi are more likely than ordinary moles to become cancerous. While dysplastic nevi are common and many people have a few of these abnormal moles, having more than 50 ordinary moles also increases the risk of developing melanoma. [11]
However, a melanocytic nevus is benign, and melanoma is malignant. Most melanocytic nevi never evolve into a cancer, with the lifetime risk for an individual nevus being 1 in 3000 for men and 1 in 11 000 for women. [5] Moreover, dermatologists have a standardized system for determining whether a skin lesion is suspicious for malignant melanoma.
The growth rates of benign and malignant tumors also differ; benign tumors generally grow more slowly than malignant tumors. Although benign tumors pose a lower health risk than malignant tumors, they both can be life-threatening in certain situations. There are many general characteristics which apply to either benign or malignant tumors, but ...
Border: The border around the spot has scalloped, irregular or poorly defined edges. Color: The spot contains various shades of black, brown, tan, white, red or blue.
An atypical mole may also be referred to as an atypical melanocytic nevus, [2] atypical nevus, B-K mole, Clark's nevus, dysplastic melanocytic nevus, or nevus with architectural disorder. [3] Dysplastic nevi often grow to larger than ordinary moles and may have irregular and indistinct borders.
According to the Skin Cancer Foundation, basal cell carcinoma “can look like open sores, red patches, pink growths, shiny bumps or scars or growths with slightly elevated, rolled edges and/or a ...
Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. [1] It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye (uveal melanoma).
