Difference between mole and melanoma

The difference between moles and melanoma lies in the different nature of the lesions, different predisposing populations, and different symptoms. The details are as follows:

1. Different nature of lesions: Moles are usually benign tumors formed by the accumulation of mole cells, which generally do not threaten life. Melanoma is a malignant tumor originating from melanocytes, which may cause secondary melanocytic nevus. If not actively treated, it may threaten human life.

2. Different susceptible populations: Moles are common in all age groups, while melanoma is common in middle-aged people. The incidence rate in men is higher than that in women. It is common in people with a family history of melanoma and those who have suffered skin trauma.

3. Different symptoms: The symptoms of moles are diverse and complex, showing as raised skin surface or level with the skin, dark brown or black in color, large or small in size, without pain or itching. Melanoma is manifested by ulceration, pain, bleeding and other symptoms at the pigmented area, and may metastasize to the liver, lungs and other organs.

If a raised swelling appears on the skin surface, it is recommended to go to the hospital in time for treatment after the cause is determined.
