Causes of laryngeal cancer. Laryngeal cancer is caused by changes in the cells of the larynx, although it's not clear exactly why this happens. All cancers begin with a change in a cell's DNA. DNA provides our cells with a basic set of instructions, such as when to grow and reproduce.his causes the cells to reproduce in an uncontrollable manner, producing a growth of tissue called a tumour. It's not known why the DNA inside the cells of the larynx is affected in cases of laryngeal cancer.
Other causes of syringomyelia include an injury to the spinal cord, spinal tumors, or mass lesions. Arachnoiditis (inflammation of the thin membrane just inside the dura membranc) can also create an abnormal spinal cavity, and cause a syrinx to develop.he most common area for a syrinx to develop is in the cervical spine (neck), with the second most common in the thoracic spine. As the syrinx grows in size, it may cause scoliosis (abnormal curve of the spine), which is best evaluated by special x-rays of the spine.
