Sudden growth of nevus on the right hand may be caused by pigmented nevus, malignant melanoma and other reasons.
1. Pigmented nevus: The organism is exposed to strong ultraviolet rays in daily life, use of inappropriate cosmetics, and trauma to the right hand, which leads to abnormal secretion of melanocytes in the hand and excessive deposition of melanin, and a mole will suddenly grow in the right hand.
Moles generally do not affect the health of the body and only affect the aesthetics, so they do not need special treatment. Those who feel that they affect the aesthetics can be treated with laser therapy, which breaks down the melanocytes and then disintegrates them, and then they are phagocytosed by the human macrophage to get rid of them.
2. Malignant melanoma: if a mole grows suddenly on the right hand, which is asymmetric, dark in color, more than 5mm in diameter, surrounded by bulges or satellite-like changes, and grows faster, it should be suspected to be malignant melanoma, and should be examined by a doctor in time and advocated to be actively resected at the early stage of treatment.
If a mole grows suddenly on the right hand, one should actively observe the changes of the mole and go to the hospital for treatment if there is any abnormality.
