Colon Cancer Screening: New Non-Invasive Method Investigated
Date: 15/11/07
Keywords:
For more than three decades, optical colonoscopy (OC) has been the primary method of colon cancer screening. But an alternative method called computed tomographic colonography (CTC) has been developed over the past few years. Obviously neither method is a day at the beach, but is CTC as effective as OC?A friend of mine named Charles (who's nearing his 60th birthday) recently mentioned that he's planning his second tubing expedition.
'Tubing' is his metaphor for 'colonoscopy.' When you allow doctors to sedate you and insert a camera where no ray of sunshine ever falls, it helps to have a sense of humour about it.
But according to a new study, Charles may not need to go tubing because a tube-free method might work just as well. No tube sounds promising, but is this alternative screening technique really preferable?
Double jeopardy
For more than three decades, optical colonoscopy (OC) has been the primary method of colon cancer screening. But an alternative method called computed tomographic colonography (CTC) has been developed over the past few years. This method is also known as 'virtual colonoscopy' because it's minimally invasive, requiring a catheter to be inserted into the rectum to fill the colon with air, followed by noninvasive optical scan.
