Lasers in the treatment of cancer of the prostate. An overview.

The results of therapy of prostate cancer with laser therapy either in the experimental animal model or in human application are preliminary and rudimentary. Difficulty in access to the prostate, variability in depth of laser penetration and problems in assessment of therapeutic attempts makes it impossible to be dogmatic about re the future application. The tumour does however respond to Nd: YAG and P. D. T. therapy and it is possible that the crude attempts to date will be supplanted in the future by more refinements that will enable laser energy to be harnessed.
