Cancer
Cancer is a malignant growth or tumor caused by abnormal and uncontrolled cell division. The hallmark of cancer is its potential ability to invade neighboring tissue or to spread (metastasize) to other parts of the body through the lymphatic system or the bloodstream.
Early cancers may have done neither, remaining localized to the tissue of origin. The majority of cancers in the head and neck are classified as carcinomas.
Laser Removal of Vocal Cord Cancer with Bilateral Disease
For treatment of early vocal cord cancer, both laser excision and radiotherapy are in competition as good treatment modalities. See also Early Vocal Cord Cancer: Remove with a Laser, or Radiate? Often, radiation is used when disease is bilateral, in the interest of preserving voice.
This is an example of the ability to do fairly extensive laser surgery bilaterally, yet preserving good voice. This man had a friend who had severe difficulty with radiation, and he was therefore opposed to that option.
