Stem Cells and Cancer

Ok, I found this very interesting. In a recent report, scientists are now developing a way to fight cancer using stem cells from bone marrow. Now, I know that stem cell research is controversial (I for one believe in it as long as the cells are from your own body), but if they can take a portion of some of YOUR own bone marrow and eliminate your cancer, then I am all for it. The stem cells attack only tumors and not healthy tissue and your body will not recognize them as foreign invaders, leaving it safe and effective.
So far this study has been conducted on mice and in cultures, but has proved to be effective in lung, breast, and cervical cancers. Not to mention it is showing a promising 38% success rate. Though this is not available as of yet, the hope is for human trials to begin in 2 - 3 years.
