Head and Neck Cancer
Head and neck cancer begins with the abnormal growth of cells. These cells multiply out of control, eventually forming a tumor in part of the head or neck. As the tumor grows, it can form a lump, a sore, or an abnormal patch of white or discolored tissue.
Without treatment, the tumor can invade and destroy nearby bones and soft tissues. Eventually, it can spread (metastasize) to lymph nodes in the neck and to other parts of the body.
