Moles and skin tags are usually considered to be benign, but they could indicate more serious problems. Skin tags are tiny, squishy nodules that typically protrude from the skin, whereas moles are black skin patches that can appear anywhere on the body. In many cases, bacteria that can make people sick can breed in skin tags. Moles and skin tags are prone to turning into cancer. It is crucial to keep an eye on their growth and remove them if they begin to alter.
