Is it a disease when a mole grows up?

Generally speaking, moles are benign tumors and will not cause lesions. However, if the mole grows in the armpit or on the lips, frequent friction will cause the mole to become inflamed, which can easily lead to lesions. It is recommended to go to the hospital for removal. So, if a mole grows up, does it become a disease? This requires specific analysis because the lesions are not necessarily malignant.

From a medical point of view, a mole is a benign skin tumor, which is divided into many types, such as pigmented nevus, connective tissue nevus, sebaceous gland nevus, etc. When people talk about "moles", they usually refer to pigmented nevi, also known as melanocytic nevi.

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, bleeds, or has satellite lesions around it, it indicates that it has become malignant and should be removed promptly.

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. 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.

Melanoma is a type of skin cancer, but compared with other skin cancers, it is a more "evil" type. The disease progresses rapidly, is easy to metastasize, and has a high mortality rate. The main causes of the disease are: ultraviolet radiation, excessive sun exposure, malignant transformation of dysplastic moles, heredity, trauma, endocrine abnormalities, chemical carcinogens, and immune deficiency or immunodeficiency.
