Seborrheic keratoses are non-cancerous tumors associated with aging skin. They’re much like warts, at the cellular level, only they’re not driven by any virus, as warts are. We actually don’t know why they appear. They can vary in shape, size, and darkness. They’re very thin, and easy for your dermatologist to take off. They’re not dangerous.
