When something damages a sound cell, the cell partitions to repair the damage. Once the damage is repaired, it quits isolating. That is typical cell repair, says Dr. James Davis, the therapeutic executive at the Duke Center for Smoking Cessation. "A cancer cell, then again, doesn't know when to quit partitioning. Typically, a phone in the lung or another organ knows precisely what to do. Every cell includes its capacity inside the organ.
