Treatment for skin bumps depends on the underlying cause. In most cases, you will need no treatment, but you should see your doctor if you are uncomfortable, you don’t know the cause of the bumps, or you suspect skin cancer or an infection. Skin bumps that are harmless and need no treatment can be removed for cosmetic reasons. For instance, your dermatologist can freeze skin tags or warts to remove them. You can have cysts or lipomas removed surgically. Other bumps that are itchy or irritated may be treated with topical ointments. thank you.
