Last year I had to have a polyp removed surgically. When the doctor performed a colonoscopy he found a suspicious area and performed a biopsy (this was embedded in the mucosa so he could not snip it off like he would a polyp). The biopsy showed it was an adenoma with high-grade dysplasia - or a step away from cancer. The first surgeon I went to was going to perform a "temporary colonoscopy", the second one said he would just remove the growth (unless they found it was deeper than anticipated). The week before the surgery I went to the library and happened to find this marvelous little book. And I must say, it alleviated my fears greatly!! All turned out well, with same-day surgery and no complications. Now it is time to have another test - and the worries and fears have come back. So, now I am going to order this book to have on hand whenever I become too concerned about "what's going on"? This is a very self-educating, easy to read book and would be helpful to practically everybody who has had any bowel discomfort or GI problems.
