Exercise is the key to a health body and a healthy mind.

It is believed that one hour of daily vigorous exercise or two hours of less strenuous activity is now linked to a lower risk of colon cancer, according to the results of a recent study.

Cycling, Jogging, running, pumping iron, swimming, and even housecleaning can do the trick, as demonstrated by research conducted with 413,000 people in 10 European countries.

Of those studied, people with the highest level of exercise were 22 percent less likely to develop cancer and 35 percent less likely to develop tumors on the right side of the colon. Those of normal weight enjoyed a greater benefit, but exercise was also beneficial for the overweight and obese. Exercise did not have a protective effect against rectal cancer.

In a clinical trial conducted at the University of Nottingham, scientists gave a vaccine to 67 colorectal cancer patients before and after surgery to remove the cancerous tumors. The British researchers say they have developed a vaccine that stimulates the immune system to fight colorectal cancer cells.Vaccine trials are not new in the search for effective cancer treatments but many times they are given as a last resort and are not effective. The vaccine is named 105AD7. The antibody in the vaccine was cloned from a patient who survived seven years despite liver metastasis from colorectal cancer. Lindy Durrant, study senior author and professor of cancer immunotherapy said “This is very unusual, as most patients die within a year of getting liver metastasis. I thought if this antibody had helped this patient, if we could clone it, it might help others”.

The researchers reported in the current issue of Clinical Cancer Research that the vaccine helped stimulate immune cell production in up to seventy percent of the patients studied.
