A medical treatment apparatus applies heat to the skin so that the skin may be gradually collapsed without incision and thereby a tumor mass beneath the skin may be exposed to the outside and allowed to be removed. This apparatus includes a cup-like container, oil, and a wick. The container is placed on the first part of the skin that covers a target tumor, and has a vertically penetrated cylindrical shape. The oil is contained in the container and is in contact with the first part of the skin. The wick is placed in the oil so as to catch flame. The temperature of the oil gradually rises while the flame lives on the wick, so heat is continuously applied to the first part of the skin from the oil. This apparatus may further include at least one of a cooling unit and a cooling water pipe placed at an outside of the container, enclosing the container, being in contact with the second part of the skin that is located at the outside of the container, and cooling the second part of the skin. This apparatus may also include an adhesive interposed between the container and the first part of the skin.
