Stem cells

Stem cells have been a highly debated issue for many years now - and not just due to the fetal stem cell issue - because of the possiblity of cancer stem cells. They have been lauded as the next best thing since sliced bread in the fight against cancer and other diseases. But what if there were cancer stem cells which were resistant to treatment and regrew tumor cells? This is the latest theory meaning that even aftrer treaqtment they will regrow.

So maybe the thoughts on cancer treatment need to focus not on the tumor but on the cancer stem cells to prevent regrowth? This would be a whole new area of focus in cancer research and treatment. Hmmm... More studies (of course) will be needed (we need to keep the researchers busy) but we need to realize that this also shows us that with all the progress we have made in treating cancer, we still have a long way to go.
