The ray of hope comes to the cancer patients that the cells from your wife or husband, children or friend or neighbor who is immune to cancer may help in curing the dangerous disease.

Dr Zheng Cui, scientist from the Wake Forest University School of Medicine in North Carolina, has showed that granulocytes, a type of immune cells taken form individual free from cancer killed the tumor cells within 24 hours at the rate of almost 97 per cent.

On successful treatment of cancer in laboratory mice by the white blood cells (WBC) of resistant mice, the US Food and Drug Administration (FDA) waved flag to the researchers to proceed with human trails.

Each and every individual possess the natural killer (NK) cells in fighting with the cancer cells, as the play a major role in identifying and destroying the tumors. The extent of the influence on the cancer cells of NK cells yet to be revealed.

According to the New Scientist magazine, by the next summer the human trails may takeoff. Dr Zheng Cui hopes that if these trails get best results in humans as in mice lot of cancer deaths can be stopped.

This will give hope to the cancer patients worldwide that they may survive happily for at least two more years.
