FILE - In this April 19, 2007 file photo, a lab officer cuts a DNA fragment under UV light from an agarose gel for DNA sequencing as part of research to determine genetic mutation in a blood cancer patient, in Singapore, which prides itself as an advanced medical treatment and research hub. New research shows a sharp escalation in the weapons race against cancer, with several high-tech approaches long dreamed of but not possible or successful until now. At a weekend conference of more than 30,000 cancer specialists, scientists are reporting new tactics to spur the immune system to attack a broad range of cancers, new drugs that attack the disease while sparing healthy cells, and new ways to tell which patients will benefit from which drugs.
