The lymph node is not larger than 3 centimeters and one of the following is true: (1) the tumor is not larger than 2 centimeters at its widest point and may have one high-risk feature (is thicker than 2 millimeters, has spread into the lower layer of the dermis or into the layer of fat below the skin, has grown and spread along nerve pathways, began on an ear or on a lip that has hair on it, or has cells that look very different from normal cells under a microscope); or (2) the tumor is larger than 2 centimeters at its widest point; or (3) the tumor is any size and has two or more high-risk features (is thicker than 2 millimeters, has spread into the lower layer of the dermis or into the layer of fat below the skin, has grown and spread along nerve pathways, began on an ear or on a lip that has hair on it, or has cells that look very different from normal cells under a microscope).
