Some people have color spots known as moles or birthmarks, including congenital and acquired. These patches are often benign color changes, but they can turn into malignant changes that warn of melanoma.

Moles or birthmarks are the most common benign skin changes, and occur when several pigment cells form melanin, said Professor Christopher Gephardt of the University of Hamburg-Eppendorf Medical Center.
The Soul
The mole appears as a spot in different colors for the skin such as brown, black or blue. The mole rarely turns into a malignant skin change, so eye-catching spots call a dermatologist.

Moral or acquired?
Gibhart added that moles are divided into congenital and acquired, explaining that there is no precise cause for congenital moles. Acquired moles, which occur only after birth or after the first two years of life, occur as a result of a combination of genetic predisposition and ultraviolet radiation, often in childhood and adolescence.

Age spots also arise when increased exposure to ultraviolet radiation, knowing that people with light skin are more likely to appear.
Gibhart noted that moles are often benign color changes, but they can turn into malignant changes that warn of black skin cancer. He explained that the greater the number of spots, the greater the risk of black skin cancer, people with more than 50 spot, the risk of developing black skin cancer by five times.
The Soul
People with more than 100 spots are 10 times more at risk. People with first-degree relatives (parents and siblings) are also more likely to develop black skin cancer.

Mole examination
For her part, German dermatologist Katarina Schurings said that it can be judged that the mole is normal or not by examining the following different aspects:
The Soul
1. Is the mole asymmetrical?
2. Does it have an irregular limit?
3. Do they have different colors?
4. Is it larger than 6 mm in diameter?
Do you rise from the surface of the skin?
The Soul
In general, you should see a doctor if you notice anything strange in the moles, such as itching or peeling.
The Soul
If tests show signs of disease, the chances of recovery are increased by early treatment. If malignancy is suspected or even skin cancer, the mole is surgically removed.
