CHICAGO (AP) ? New research shows a sharp escalation in the weapons race against cancer. Scientists are reporting success with several high-tech approaches long dreamed of but not possible or proven to work until now.

At a weekend conference of more than 30,000 cancer specialists in Chicago, researchers described new tools to make the immune system attack a broad range of cancers, new "smart bomb" drugs that target the disease while sparing healthy cells, and new ways to predict which patients will benefit from which treatments.

One of the best things about all of this: People feel better while going through treatment because the new approaches have fewer side effects.
