  6. Gene domino effect behind brain, pancreatic tumors AP - Fri Sep 5, 8:49 AM ET Avg. Rating: 4.6

    WASHINGTON - Scientists have mapped the cascade of genetic changes that turn normal cells in the brain and pancreas into two of the most lethal cancers. The result points to a new approach for fighting tumors and maybe even catching them sooner. Genes blamed for one person's brain tumor were different from the culprits for the next patient, making the puzzle of cancer genetics even more complicated.
