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.
If a mutation then occurs in the second copy of the susceptibility gene in one somatic cell, that cell begins to divide uncontrollably. As the cell divides, the offspring cells inherit these mutations and perpetuate the cancerous characteristics. Alternatively, two somatic mutations may occur spontaneously in the same cell. For example, exposure to ultraviolet wavelengths in sunlight, or to cancer-causing chemicals, can cause somatic mutations.
