Any changes in moles can lead to their degeneration. Special attention should be paid to the shape, color and size, reports zakon.kz with reference to 360.

Oncologist Irina Dobretsova told about this.

A person can make self-diagnosis only on the basis of a certain system. A safe birthmark should be evenly spaced, while having smooth edges. Also, a person should pay attention to color changes.

If you see that the color of the mole begins to change – on the one hand it is lighter and on the other darker. In this case, you also need to see a doctor, – said Dobretsova

Initially, it is best to remember the approximate diameter of the mole, so that it is easier to monitor possible changes and timely prevent the development of cancer.
