My sister died in 2001 died of colon cancer due to a very unhealthy lifestyle of literally living on tea only, and smoking. Colon cancer has subsequently become a very real "issue", and at one time I got really paranoiac. As soon as I noticed any sign associated with the condition, I would get frantic. I eventually went for a colonoscopy and was assured my colon is healthy. The doctor did however recommend I have one done every 10 years just to be safe. In order to not subject myself to this again, I have resolved to keep my colon healthy and clean. I use an all natural herbal colon cleansing treatment which has not only kept my colon clean, but also keeps me regular which is very important in preventing hemorrhoids (something else I have once suffered from). Your article does well in alleviating any fears someone may harbor in going for a colonoscopy however.
