Parkinsons

I saw a documentary a few years ago now about a lady who could also smell illnesses one of them being cancer I wonder if there is any truth in it ?

There are dogs with similar skills.

I have read an article about a woman who has been shown to be able to detect Parkinsons by the smell. She and her husband had some cross words in the months leading up to his diagnosis. I'm sure it is thought to be a skill that others have too.

She has been working with a research lab to try and isolate the molecules in the smell, trying to find a diagnostic test for the disease. She seemed to be amazingly accurate and able to identify sufferers way before their official diagnoses.
