Moles are the most common growths in humans. They can be present at birth or acquired throughout life. Moles can appear anywhere on the skin in various sizes and shapes. They are made up of melanocytes, skin cells that produce melanin (dark pigment).
Nevi (Singular: Nevus)
Moles are the most common growths in humans. They can be present at birth or acquired throughout life. The incidence of nevi increases throughout childhood, peaks in adolescence, and typically wanes in older adulthood. Nevi evolve and change throughout childhood and during pregnancy.
Moles can appear anywhere on the skin in various sizes and shapes. They are made up of melanocytes, skin cells that produce melanin (dark pigment). Moles typically evolve and grow as we do. They generally begin as flat brown spots, similar to a freckle, that, over time, may grow larger, become elevated, and grow hairs. Certain types of moles carry a risk for developing malignant melanoma, a serious form of skin cancer. Sunburns, particularly in childhood, can increase the risk.
Dysplastic Nevi are unusual moles that may resemble melanoma. People who have them are at increased risk of developing single or multiple melanomas. The more of these moles someone has, the higher the risk; those who have 10 or more have 12 times the risk of developing melanoma compared to the general population. Dysplastic nevi are found significantly more often in melanoma patients than in the general population.
Melanoma is the most serious form of skin cancer. However, if it is recognized and treated early, it is nearly 100 percent curable. But if it is not, the cancer can advance and spread to other parts of the body where it becomes hard to treat and can be fatal. While it is not the most common of the skin cancers, it causes the most deaths.
Seborrheic keratosis, also known as “Seborrheic verruca”, are common skin growths. These benign (non-cancerous) growths can occur almost anywhere on the skin. Some people get just one while others develop many.They appear in various colors, from light tan to black. They are round or oval, feel flat or slightly elevated and range in size from very small to very large. They can resemble warts, though they have no viral origins. They can also resemble melanoma skin cancer, though they are unrelated to melanoma as well. Because only the top layers of the epidermis are involved.
