President Bush is keeping up with his colon cancer screenings. Good thing -- because five small growths were found and removed during his latest scan on Saturday.

The polyps found inside his large intestine were all less than one centimeter in size and did not appear suspicious. Still, they were sent to the National Naval Medical Center in Bethesda, Md., to be microscopically examined for signs of cancer. Polyps can turn into cancer, so finding them early is the best way to prevent the disease and improve the odds of surviving it. It takes 48 to 72 hours for pathology reports to come back, but the majority of polyps this size are unlikely to be cancerous.

Bush is no stranger to polyps. In 1998, after a similar scan, two polyps were found. In 1999, two more surfaced. And while none were found during his 2002 screening, he has become a prime candidate for regular examinations. For the general population, colonoscopy tests are recommended every 10 years.

Cancer drug Gleevec, used for the treatment of chronic myeloid leukemia (CML), has been pulled out of another round of testing so it can get to work stopping the return of a rare stomach cancer. It's that good, according to findings announced on Thursday.

The promise of Gleevec should make it standard treatment for people with gastrointestinal stromal tumors (GIST), a stomach and intestine cancer diagnosed in 5,000 to 6,000 Americans each year.

The drug has already been used for patients whose disease is too advanced for surgery. Now it will be used for those whose tumors can be removed. The drug will be administered for at least one year post-surgery.

More than 600 people participated in this Gleevec trial. Each person took either Gleevec or a sugar pill for one year after surgery. After the one-year mark, cancer returned in 17 percent of people taking the sugar pill and in 3 percent of people taking the actual drug.

Since 50 to 90 percent of GIST cases recur over time, this is great news, say researchers who call Gleevec a highly targeted cancer drug with few side effects.

One week ago, researchers found themselves humbled by the disappointing fact that promising cancer drug Avastin had failed to help patients with pancreatic cancer live longer. In fact, not only did the drug fail to extend survival, it actually caused adverse side effects such high blood pressure and bleeding in the stomach and intestine.

In a study of 600 patients with advanced pancreatic cancer, those who received Avastin in addition to standard chemotherapy lived for only six months -- the same amount of time as those who received chemotherapy alone.

Earlier studies predicted Avastin might improve survival. It worked in patients with advanced colorectal cancer. And so it was no surprise that crowds of pancreatic cancer patients wanted a shot at this potential wonder drug that in the end turned out -- for them -- to be not so wondrous.

A report in the October issue of the American Journal of Gastroenterology states that capsule endoscopy can aid in the identification and management of small bowel tumors. Capsule endoscopy lets your doctor examine the lining of the middle part of your gastrointestinal tract. Your doctor will use a pill sized video capsule called an endoscope, which has its own lens and light source and will view the images on a video monitor.

Capsule endoscopy helps your doctor evaluate the small intestine. This part of the bowel cannot be reached by traditional upper endoscopy or by colonoscopy. The most common reason for having this procedure is to search for cause of bleeding from the intestine. It may also be used to detect polyps, inflammatory bowel disease, ulcers and tumors of the small intestine.

Dr. Adam Bailey from the Royal Prince Alfred Hospital in Sydney says "Capsule endoscopy has the potential to achieve earlier diagnosis of small bowel malignancies offering a greater chance of cure. It should be used early in the course of investigation of suspected small bowel disease, avoiding the delay that has let to many patients having advanced disease at diagnoses.
