WHAT IS CANCER AND WHICH ARE ITS STATISTICS? Assignment (in the media) What is cancer and which are their statistics? Cancer is the name given to a collection of related diseases. In all types of cancer, some of the body’s cells begin to divide without stopping and spread into surrounding tissues. Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place. When cancer develops, however, this orderly process breaks down. As cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed. According to the National Cancer Institute b y 2025, an estimated 2.1 million people in the United States will be diagnosed with cancer every year. This is a 31-percent increase from 2012 that is due in part to the aging of the U.S. population and the greater use of cancer screening. The estimated number of annual cancer-related deaths is expected to increase even faster, by 37 percent, from 620,000 to 850,000 by 2025. The independent variable in this study is the age, sex, racial, and ethnic group. The dependent variable is the amount of people dying or surviving due to cancer.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
