For seniors who are concerned about taking affordable, preemptive steps to promote their senior health, here are five steps that, if taken, can greatly reduce the risk of contracting colorectal cancer.  The results are from a study in Europe that were recently published in a medial journal in Britain.  The researchers found that folks who lost weight,  limited their consumption of alcoholic beverages, stopped smoking, maintained a healthy diet and exercised about 30 minutes a day reduced their risk of colorectal cancer by more than 20%.  This was the first study that combined all five factors, because earlier studies had considered these factors individually in isolation from the others.  It is not certain why following these recommendations helps to  prevent colorectal cancer, but suffering from high insulin and diabetes are known risk factors for colorectal cancer.  Lack of physical activity and obesity lead to high insulin states, that typically lead to the growth of cancer cells.  The European study found that women who lost weight sufficient to reduce their waist size to 35 inches and men to reduce their waist size to 40 inches were in the healthy zone.  In terms of alcohol consumption men who consumed no more that 14 drinks per week and women no more than 7 were also remained in the healthy zone.  In summary seniors who want to take preemptive aging steps to foster their senior health would be well advised to implement these five lifestyle recommendations.
