Why cancer treatment fails ? – This question is raised by family members of cancer patients around the world and Doctors and Researchers were unable to answer. Many recent studies have shown that one of the main reason for failures in cancer treatment could be lack of precision in targeting the right cells. But what are right cells ?. This was not difficult to answer as most researchers believed that they are the cancer stem cells but were difficult to identify as there were no proper methods available to identify them. If these cells can be identified and distinguished from other cells, treatment strategies could be more focused.
Four recent studies found a way to identify the cancer stem cells. If this is found in other cancers also, then it will change totally the parameters used for evaluating success of chemotherapy and method of treating cancers.
