Occasionally, tumors may recur in a site previously irradiated. In selected situations, it may be possible to treat the area with stereotactic radiation using CyberKnife. The technology is appealing since it allows treatment to a small defined area with minimal dose to surrounding normal tissues.

Areas of treatment include lymph nodes of the neck, tumors of the oral cavity and pharynx and larynx.
