Exercise changes the body's response to Cancer

Those people diagnosed with cancer, the risk of cancer death falls as physical activity rises, according to a new analysis of more than 70 existing studies. Researchers found the same holds true for everyone, supporting the current World Health Organization recommendation of moderate physical activity to combat the risk of chronic disease, they write in the British Journal of Sports Medicine.
The WHO recommends two and a half hours of moderate exercise per week for some health benefit and five hours of moderate exercise per week for additional benefit. Half as much time per week of vigorous physical activity, like running, may confer the same benefits.
There are no specific recommendations for physical activity levels to combat cancer risk, although more activity has been tied to lower risk of death from breast, colorectal and prostate cancers.
They also looked at data in terms of MET-hours, a measure of the relative amounts of energy expended in given activities and time spent doing them. Resting represents 1 MET, while a 4-MET activity like brisk walking uses four times as much energy, according to the U.S. Office of Disease Prevention and Health Promotion. Doing a 4-MET activity for 30 minutes equals 2 MET-hours.
Cancer survivors who completed at least 15 MET hours per week of physical activity were 27 percent less likely to die from cancer.

Cheaper anti-cancer drugs for humans might ultimately stem from a new study by University of Guelph scientists into a kind of microbial "bandage" that protects yew trees from disease-causing fungi.
