Mole is a kind of benign lesion, which is related to local pigmentation and blood circulation disorder, so mole on foreskin is also a normal phenomenon, the same reason as mole on other parts of the body, which is a mole formed by pigmentation due to various reasons and does not need special treatment. If the appearance of the mole is smooth and there is no obvious change in size, it is benign and does not need special treatment. If the mole has obvious erosion and increases significantly in size within a short period of time, it is considered to be a malignant melanoma and needs to be treated in the hospital through relevant examination. The foreskin and the glans should be cleaned with warm water every night, and the stimulation of the mole by the foreskin scale should be reduced. If the foreskin is too long, circumcision should be done in time, which will obviously reduce the inflammatory stimulation.
