One year ago, the PS4 price was the more tempting deal: $399 for the console and DualShock 4 controller. Xbox One was expensive at $499 for the system, Xbox One controller and Kinect.
Cancer is a term used for diseases in which cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer cells can spread to other parts of the body either through the bloodstream or lymph systems.
This common outcome is somewhat unexpected, as cancer is marked primarily by uncontrolled cell division, an immortal cellular state. In 1961, cellular aging was first described by Hayflick and Moorhead. They showed that human cells in culture do not divide indefinitely but reach a limit (called the Hayflick limit) of replication and stop all further division. Cells approach this limit by slowing their divisions and entering cellular senescence, a dormant period.
