I have 3 rather obvious black moles on my body. These moles were basically there since birth, but I am worried if the moles can cause skin cancer.
If this nevus is persistently large, you should go for a pathological examination to see what nature it is, and if it has some cancerous nature, then it should be treated as soon as possible.
If you have a lot of moles on your body, it is recommended to perform local cryosurgery or local excision surgery, because many moles may have the chance of cancer, so it is responsible for your safety to remove them earlier.
This kind of performance is considered to be a kind of pigmented mole, but at present it is not rapidly increasing or blackening, so to a certain extent there is no big problem, if you are really uneasy, you can choose to use laser treatment, but normally there is no need to do any correction.
