- Abstract:
The article reports on the research conducted by Robert Weinberg, the country's pioneering biologists, on how cancer spreads in the U.S. Cancer cells evade the immune system, travel down blood-vessel thoroughfares, colonize distant regions of the body and recruit normal cells to support their cause. He played a leading role in defining the battleground in the war on cancer because he was the first to discover cancer-causing gene and the first to isolate a human tumor-suppressing gene. Recently, he studies on metastasis and found that cancer cells in initial tumor produce enzymes that break down the surrounding tissue, clearing the way for the cells to invade it and some of it are able to enter the bloodstream and were able to lodge in another place thus metastasis takes place.
