I am a 28 year old male, drink and smoke a lot. Since a few weeks, there is a mass under my chin that has been growing and to date still is growing. It s painful to the touch, hard, and hardly mobile. I have no fever (though I felt ill a few days ago), no shortness of breath, no pressure on my chest, no itchyness, no rash , no special symptoms I can think of. I m worried it may be cancer .
