EXERCISE BLOCKS CANCER GROWTH

The anti-cancer effects of exercise are due to increases in a protein that blocks cell growth and induces cell death, according to Australian researchers.
The protein, IGFBP-3, inhibits another protein, IGF-1, thereby blocking IGF-1's proliferative effect on cell growth, the study suggests.
Dr. Andrew Haydon and colleagues at Monash Medical School in Melbourne found that among study subjects who were physically active, an increase in IGFBP-3 was associated with a 48 percent reduction in colon cancer-specific deaths.
IGF-1 has been shown to stimulate cell growth and promote the formation of new blood vessels, which tumors need to grow.
