Laser surgery in the treatment of cancer

Research on the medical applications of the free electron laser is being carried out in several institutions, including our own. The initial studies point to many new wavelengths and a higher output of the various wavelengths that are presently being used. The search continues for chromophores that may be administered orally or intravenously that will concentrate in tumors. Thus, medical laser technology, just over 25-years-old, is expanding rapidly. Research will doubtless lead to its increased refinement and to improved patient care in the future.
