What is Cancer?Cells can become cancerous because of damage to the cell’s DNA (DNA directs all of the cells’ actions). In cancer cells damaged DNA is not repaired, and the cell will go on making new cells with the damaged DNA. These DNA may promote cell growth, interfere with growth restraint, or prevent cell death. Cancer can often arise slowly developing over several decades. The abnormal mass of cells is called a tumor. Cancer is not just one disease but many diseases.
