Thanks for sharing wpruitt. Dave Barry is great! I think there are two things most men put off too long. One is the colonoscopy, the other is a prostate exam. If you are in the right age bracket or if you have a family history, DO BOTH!
There is actually a non-invasive study they are using now. It's called the "Virtual Colonoscopy". it is basically a CT scan of your abdomen. It uses a specific set of software to reconstruct the colon virtually. If something is suspicious, then a real colonoscopy is in order.Thing is, the scan is very expensive and some insurance carriers are not covering it since it is a new technology. like all things technical though, it will be affordable in the near future.
