Science and technology daily, Beijing, Feb. 17 (reporter Chen Dan): can sports help fight cancer? Scientists from Copenhagen University in Denmark have confirmed for the first time that running can help slow down the growth of tumors through mouse experiments.
 
According to the website of new scientist, a research team led by penelai hoyman of Copenhagen University tested the effect of exercise on five different cancers, including skin cancer, lung cancer and liver cancer, using mice with cancer. They ran mice 4 to 7 kilometers a night, and found that the anti-cancer ability of the immune system of mice was improved, which not only prevented new tumors, but also slowed down the growth of the original tumors by as much as 60%.
 
This is the first time that experiments have proved that exercise can directly control the growth rate of tumor. The researchers found that exercise promotes the production of adrenaline, a "stress hormone" that in turn stimulates the immune system to release natural cancer fighting "killer cells" into the blood. During exercise in mice, muscles produce a substance called interleukin-6, which can lead "killer cells" to attack tumors.
 
Lee Jones, of memorial Sloan Caitlin cancer center in New York, said that scientists had known that exercise could affect the activity of natural "killer cells", but this is the first time through experiments to prove that exercise can directly help these cells fight against tumors, which is a puzzle that has been missing for a long time.
 
However, running didn't shrink the tumor of the mice, but only made them grow less quickly. This shows that the existing tumor can not be reversed by movement.
 
For humans, there is also some evidence that exercise after menopause can prevent the recurrence of colorectal and breast cancer, hoyman said. Her team plans to next track cancer patients to see if their exercise patterns can have similar positive effects.
