It can have an odour but not generally detectable by humans. Dogs can smell it and some have been trained to 'alert' on the smell to identify the location.

Dogs can tell when someone has cancer.

Some cancers cause molecular changes that can be detected by analysing the released molecules. I read the other month about a new test for lung cancer that works by detecting the aroma given off solely by the cancerous lung cells.

There is some evidence that dogs, with their profound sense of smell, may be able to detect cancer.
