CANCER RESEARCH PROJECT By Chantal Deller Cancer is a group of diseases that are cell-related. In the event of cancer‚ regular body cells begin changing and growing in improper ways. Regular cells grow‚ divide and eventually die off. Irregular cells (cancerous cells) simply keep growing and divide out of control they don ’t die. Different types of bodily tissues are made up by different types of bodily cells bone cells make up bone tissue‚ for example. Because of this‚ the different types

Per.1 2-13-13 Cancer reflection Is cancer a disease due to genetics or environment? Cancer is a disease both caused by genetics and environmental factors. Each person has either proto-oncogenes or oncogenes. These are the genes that are responsible for regulating cell division. When a person has an oncogene it is a mutation of a proto-oncogene. The oncogene (dominant gene) tells the cell to continuously divide. This can be a problem if the cell is cancerous. Cancer cells are caused by a mutation

Stem cells -are biological cells found in all multi cellularorganisms‚ that can divide (throughmitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells. In mammals‚ there are two broad types of stem cells: embryonic stem cells‚ which are isolated from the inner cell mass of blastocysts‚ and adult stem cells‚ which are found in various tissues. In adult organisms‚ stem cells and progenitor cells act as a repair system for the body‚ replenishing
