From ABC News (Australia):

Instead of killing off cancer cells with toxic drugs, scientists have discovered a molecular pathway that forces them to grow old and die.

Cancer cells spread and grow because they can divide indefinitely.

But a study in mice, published today in Nature, shows that blocking a cancer-causing gene called Skp2 forces cancer cells to go through an aging process known as senescence - the same process involved in ridding the body of cells damaged by sunlight.
