Mapping the Genome
In 2003 researchers mapped out the first human genome. It led to an explosion of knowledge about why people are different from one another. That meant for the first time doctors could learn more about why one person gets cancer or responds to treatment when another doesn't. Researchers at Mayo Clinic have mapped out the genome of a woman with multiple myeloma. And the information from her has prompted them to change the way they treat patients with this deadly cancer.
