The basis of a mass spectrometer is to take a molecule, in the case of cancer research this is normally a protein.
The molecule is ionised (i.e. , it is given an electric charge) and is then put through an electric field. The deviation of the path of the ionised molecule then indicates the mass to charge ratio of the molecule. On a protein molecule that has undergone some sort of change to the normal (e.g. via a post translational modification) this will give a different deviation as opposed to the normal unchanged protein.
The challenge then is to identify the exact difference and whether it is a viable target for a cancer drug such as a vaccine.

For quite a while, Lindy has been interested in using mass spectrometry to identify viable cancer targets. From memory, she did fund a study by Durham University several years ago.
I would imagine that this approach is relevant to research into Immunobody and Moditope vaccines as well as looking for new Glycan targets.
