What exactly are skin lesions?
An abnormal growth on the skin is called a skin lesion. There are two types of skin lesion. They are primary skin lesion and secondary skin lesion.
If a skin lesion is there when you were born or doesn’t go away for the rest of your life, it’s called a primary skin lesion.
A secondary skin lesion forms after you get skin irritation.
