Among all diseases that affect humanity, cancer ranks high as a major killer. Reports have it that cancer is responsible for about 300,000 deaths that occur in America annually. Also, it is estimated that about one million people living in the United States of America, receive treatments about cancer every year. This will really show you the level that this particular disease has reached in its onslaught in the lives of people. If adequate caution is not taken, and this scourge continues, then sooner than later, a larger percentage of the citizenry will develop cancer.
