In normal skin usually lumps appear over and under which are common in every human. One of them is known as Skin Cyst. These cysts are normally non cancerous and looks like closed pockets filled with pus, fluid or any other material. They grow like a shape of small pea over or under the epidermal layer of the skin. The cysts are the result of clogging the sweat glands, infection or contact of a foreign body with the skin. These are painless, grow very slowly and are smooth while touched. These cysts are harmless till they are infected or ruptured. Some cysts can be drained, some are medicated to shrink and some are removed surgically.
