People with atypical moles should avoid sun exposure. Skin Tags Skin tags are soft, small, flesh-colored or slightly darker skin flaps that appear mostly on the neck, in the armpits, or in the groin. Usually, skin tags cause no trouble, but they may be unattractive, and clothing or nearby skin may rub and irritate them. A doctor can easily remove a skin tag by either freezing it with liquid nitrogen or cutting it off with a scalpel or scissors. Lipomas Lipomas are soft deposits of fatty material that grow under the skin, causing round or oval lumps.
Some people develop only one lipoma, while others develop many.
Lipomas are more common in women than in men, and although lipomas can develop anywhere on the body, they are particularly common on the forearms, torso, and back of the neck. Lipomas rarely cause problems, though they may occasionally be painful. Usually, a doctor can easily recognize lipomas, and no tests are required for diagnosis. These growths aren't cancers and rarely become cancerous. Treatment usually isn't required, but bothersome lipomas may be removed by surgery or liposuction.
