Common chemotherapy drug may kill brain

U.S. scientists recently published a study showed that, for the treatment of cancer in the general effectiveness of chemotherapy drugs may do more harm than good, because these drugs will kill healthy brain cells, leading to long-term brain damage. This discovery allows scientists to find a "brain chemotherapy," the cause of clues. "Chemotherapy brain" is in many cancer patients receiving chemotherapy often complain of a side effect.

During the trial, the drugs will kill 70-100 percent of brain cells. At the same time, they can only kill 40 to 80 percent of cancer cells. Reported that the scientists of these drugs will kill a large number of the division of brain cells do not be surprised, but they pointed out: "Splinter Cell's loss will lead to complicated consequences, because these cells responsible for the nerve center added in other types of cells.
