Work in Lyon went quite well and asides from making sense of some data we welcomed a physician on board our project. Also I got to learn more about a project in which my collaborator in Lyon, Benjamin Ribba, is involved. I got to know about ETOILE (French for star), the project in which hadron therapy will be used to treat some specific patients. This type of therapy works in a similar way to radiotherapy but can be controlled so it affects only the part of the tissue affected by the tumour. For reasons that I still ignore it is mainly used in very young or older patients and requires fairly sophisticated (as in expensive and big) installations.
