Agreed. I see the future of medicine being very custom tailored to a person's genetic profile.
Not necessarily to the "person's" genetic profile. The new cancer treatment using the euphemistically named "liquid radiation" is a case in point. Once a tumor is extracted, it is "gene-sequenced" sufficiently to identify genetic markers specific to the tumor, but NOT to the patients normal cells. An aritificial antibody is then synthesized that will bond to those markers, and attached to a chelating agent that that will bond to a radioactive isotope.
At treatment time, they attach the short-lived radioisotope to the antibody/chelant, and inject it into the body. The antibody specifically bonds to any and all other tumors that may have metastesized from the main tumor, and "cook them to death" with radiation.
Frippin' INCREDIBLE!!!
