Matt Might makes the argument that there are a lot more rare diseases than many people realize. About every instance of cancer is effectively a rare disease (even though we agree to classify them according to a taxonomy), because each is caused by some kind of unique gene mutation which requires a specialized treatment, just like genetic disorders. Furthermore, once a cancer is in the body, it can keep mutating, and one can have several (or many) slightly different kinds of cancer at the same time, which is one of the primary reasons it is so hard to treat them. So by creating tools to treat rare diseases we are getting closer to curing any and every kind of cancer. And you can't prevent cancer by screening, we all become susceptible at later stages of our lives.
