How cuts can spur tumor growth

Cancerous cells flock to wounds, a study finds

The slightest scratch can cause cancerous cells to crawl to the wound and form tumors in mice, a new study finds. The work may explain why certain kinds of cancers seem to cluster around burns, surgical scars and other injuries.

“This work says that if you have a predisposition to getting cancer, wounding might enhance the chance that it will develop,” says cell biologist Anthony Oro of Stanford University School of Medicine.
