Although genetic testing and gene therapy have immeasurable potential benefit to mankind, they also give rise to many complex and troubling ethical issues that need to be resolved before a large-scale genetic treatment movement is put into place. For example, doctors have been using a form of genetic testing for years that screens for major fetal abnormalities by extracting and analyzing embryonic cells.
