This is one of the cases were you can say that competition its just obstructing the the final goal ( cure for different kind of cancers) , millions of dollars have been donated/dedicated to cancer research, still all the research result and discoveries are kept private for each of the companies on the field, this lack of knowledge transfer just cause that all new researchers have to reinvent the wheel on their on to get results that may have been obtained years ago by other researcher, the thing is there is none ( or almost none) intention of true collaboration here because its a money race.
