CT colonography most suitable choice for regular screening for cancer Colorectal cancer is the second leading cause of cancer deaths generally in most developed countries. Screening for colorectal malignancies and polyps has been shown to lower the number of deaths from cancer. Most malignancy societies and preventive task forces recommend regular screening for colon cancer. Physicians recommend colonoscopy for screening often. Unfortunately, this process is uncomfortable and sometimes outcomes in perforation of the colon, leading to death sometimes.

It is a noninvasive technique that reveals malignancy lesions and polyps with nearly the same sensitivity and specificity as colonoscopy, without the dangers of bowel perforation. This study by colleagues and Heitman compares the expenses and effectiveness of the two methods to screening, using assumed prevalences of polyps and cancers among average-risk people 50 to 74 years of age. They found that screening 100 000 sufferers with CT colonography would cost $2.3 million more than with colonoscopy, and would prevent 3.8 fatal perforations – – but simultaneously, this method would lead to 4.1 cancer-related deaths from polyps not noticed with CT, which would become malignant later. New technologies are attractive always. Because CT colonography will not physically invade your body, it has even more appeal – – it is easier for patients to accept. Its cost, however, is much higher, and its own benefit is only slightly lower than when colonoscopy is used.
