According to the American Cancer Society (ACS), cancer is the second most common cause for death in the US (2004). It accounts for 23.1% (~550,000 people) of population deaths and loses only to heart diseases with 27.2%. So about 4 out of 10 people die in US from a malignant tumor in their body. In the world overall, in only one year of 2007, 7.6 million people had a fatal case of cancer.

These are just the statistics, the so called "dry numbers", but I look around: among my close family and close friends 5 people had the tumor. This is mad!

What's the key to avoiding the disease? No one has the perfect answer, but a healthy life style is at least a way to reduce the risks. Don't smoke, avoid chemicals and radiation, eat more fruits & vegetables, do sports, take more time to rest.
