How nanotech might be used against cancer The Boston Globe
Scientists are beginning to develop microscopic tools to discover and treat cancer. Here are some general ways they hope to eventually use these innovations:
DETECT TUMORS
One goal is to spot cancer far earlier than can be done now, when treatment is likely to be most effective.

GET A CLEARER PICTURE
Highlighting tiny clusters of cancer cells should help doctors detect whether cancer has spread, or is shrinking in response to treatment -- without the need for surgery.

TARGET DISEASE
Drugs encased in packages small enough to slip through cancer cell walls kill tumors without damaging healthy cells, reducing the side effects of treatment.
