The test is expected to cost less than $50, she says.

This isn't the first time researchers have reported they're a step closer to developing a blood test for colon cancer. Just last year, two teams of European investigators said they had developed tests that look for genetic fingerprints of tumor growth and spread in the blood, for example.

Which tests will eventually make it out of the lab and into the clinic is still anyone's guess, doctors concede.

"People are putting a lot of thought into developing blood tests that are highly accurate and can detect colon cancer at an early stage," says Robert P. Sticca, MD, of the University of North Dakota School of Medicine and Health Sciences and moderator of a news briefing.

"The research is very preliminary, but [if it pans out], it will be a very useful tool given how common colon cancer is," he tells WebMD.
