The risk of kidney, liver, breast and colon cancer can probably all be reduced by exercising more and more intensively.
This is according to research published in the Journal of Clinical Oncology. The study looked at general guidelines about exercise and the risk of cancer.

In general, it is recommended to exercise for 2.5 to 5 hours a week, such as leisurely walking or gardening. Or 2.5 hours of intensive exercise such as running, swimming laps, jumping rope or walking.
Alpa Patel, of the American Cancer Society, said in a statement:“These guidelines are primarily based on their impact on chronic diseases such as cardiovascular disease and diabetes. But it is also important to avoid certain cancers.”
The study, which was done by researchers from the American Cancer Society, the National Cancer Institute and Harvard, looked at 755,000 adults. Participants had to report how often they exercised in their free time and were then followed for ten years. The researchers looked at whether they developed cancer during that period. 15 types of cancers were looked at.
The study showed that sticking to the exercise guidelines or exercising more can be linked to a lower risk of getting 7 out of 15 types of cancers. The risk of kidney cancer was reduced by 17 percent in both men and women. There was no less than 27 percent less chance of liver cancer and 19 percent less chance of Kahler's disease.
More intensive exercise reduces the risk of colon cancer in men by 14 percent. In women, intensive exercise can reduce the risk of breast cancer by 10 percent.
According to the researchers, no firm conclusions can be drawn yet, because this was an observational study, but they are cautiously assuming that more exercise affects the risk of cancer.
