Good point, blue.
As with any other research, medical research is a process of trial and error. Just because Harvard researchers found indications of tumors or pre-cancerous growth doesn?t mean that embryonic stem cell research is a total failure. It only means that our current mechanism to control embryonic cell development (and prevent malignant or parasitic growth) needs work. Setbacks are inherent in research, and failure down one avenue will lead to success in another.
But even treatments proven to be effective can be risky. Many drugs and treatment protocols are controversial at first because of risks and side effects, like radiation and chemotherapy. People suffered and died while doctors learned how to dose and properly target the cancers. Imagine if we had halted research on these treatments because of the health risks ... or because of moral concerns over using "human guinea pigs"? or because a religious group had undue influence in Congress.
