How Do Drugs Work?
... Cancer cells grow and multiply without control. Since these cells are still similar to normal cells, it is difficult to kill them selectively with drugs that can’t distinguish between the two. Many drugs currently used for cancer chemotherapy attack all growing cells, including cancer cells and norm ...
