If we compared today’s technology on human health care systems with the past’s technology, we would see many eminences of today’s technology. Thanks to the developments of the health science progress.  

 Even though it has been improved, we would be able to see that there are still so many lacks in it. In facts, there are so many kinds of health diseases that still couldn’t be cure.  

 The health treatments on cancers would be the perfect example. Today, the health science technology still could only slow down the developments of the cancer cell, or removed it. Somehow, some patients might still have some cancer cells inside.
