What is cancer?
“Although there are many kinds of cancer, all cancers start because abnormal cells grow out of control” (“What is cancer?, ” 2012).
The adult body is comprised of normal cells which mostly divide and regenerate only to replace dying cells, or to repair injuries.
“Growing out of control and invading other cells are what makes a cell a cancer cell” (“What is cancer?, ” 2012). In normal cells if the DNA becomes damaged the cell either repairs itself, or dies off. In cancer cells the cell does not die off, and continues to generate more cells with the same abnormal DNA. These damaged cells most often develop in the form of a tumor, and can often spread to other parts of the body if left untreated.[/fusion_text]

- The estimated number of new cases of cancer in the United States for 2013 is 1, 660, 290. The estimated number of deaths is 580, 350 (“What is cancer?”, 2013).
