What is the cause of moles on the head?

It is inevitable for our human body to have moles. They may be congenital or acquired due to the accumulation of pigments and cells in the dermis. There are many parts of the human body where moles can appear, such as on the nose, chest, back, etc. Some people will develop moles on their heads, which may have some effects on the human body. So what are the causes of moles on the head?

Moles are medically called "pigmented nevi". They are benign tumors of the skin that are differentiated from nerve cells. People of different ages and genders may develop moles. Generally speaking, moles are harmless to humans, but moles growing on special parts such as the palms, soles of feet, and lips require attention. Because these parts are prone to friction, moles may become malignant and develop into malignant melanoma. Therefore, it is recommended that moles growing in special parts should be removed in a timely manner. This operation can be performed in an outpatient clinic. After the operation, it is best to make a pathological section of the removed part to observe whether there are any changes, whether it has been cut cleanly, and whether it is benign or malignant.

For moles on the back of the neck, considering that they may become malignant due to friction, it is best to see a dermatologist to decide whether surgery is needed.

Except for moles in special parts of the body, moles in other parts of the body are generally divided into intradermal nevus, junctional nevus, and mixed nevus. Intradermal nevus is more common, usually protruding from the surface of the skin, relatively large and round, mostly black, and may also have hair on it. This type of nevus is a safe nevus and generally does not require treatment. Junctional nevus usually appears at the junction of the epidermis and dermis. It does not feel higher than the skin surface, is generally hairless, and is relatively dark. If this type of mole has damage around it, feels painful, has oozing water, or has satellite lesions around it, it indicates that it has become malignant and should be removed promptly.

In addition, it is important to remind you not to blindly use methods such as laser or mole removal drugs to remove moles. Because if the laser is not done well, the mole may appear to be clean on the surface, but in fact it cannot be completely eliminated; repeated laser treatment may put the mole at risk of worsening. The method of using drugs to remove moles is not thorough, and repeated stimulation may also lead to malignant transformation.
