Sudden growth of a mole on the palm of the hand is usually considered to be a pigmented nevus, and if the mole on the palm of the hand gradually becomes bigger and darker in color, there is usually a possibility that the mole may become cancerous.
Nevus pigmentosus can occur in people of all ages from infants to the elderly. It is usually caused by excessive accumulation of melanin due to a disorder of melanocyte secretion or stimulation from the external environment, resulting in sudden growth of nevus on the local skin. If there are no uncomfortable symptoms, it is recommended to remove a nevus on the palm of the hand because the palm of the hand is a friction area.
However, if a mole on the palm of the hand gradually grows larger in size and darker in color, and is accompanied by discomfort such as itching and pain, the risk of cancerous transformation of the mole may be considered, and radical surgery may be performed to remove the mole.
If a mole suddenly grows on the palm of your hand, it is recommended to go to the hospital.
