Understanding Cancer Biology
In simple terms, cancer is a group of more than 100 diseases that develops over time and involve the uncontrolled division of the body’s cells. Although cancer can develop in virtually any of the body’s tissues, and each type of cancer has its unique features, the basic processes that produce cancer are quite similar in all forms of the disease.
This 11-minute narrated animation—a part of Emory University’s Cancer Quest, a website devoted to the biology, detection, and treatment of cancer which provides an overview of the complex processes by which certain mutated cells grow unchecked, transform into cancerous cells, and migrate to other parts of the body.
The animation explains the key differences between normal and cancer cell division and describes gene mutation, oncogenes (defective genes involved in the cancer cells growth), tumor suppressors, angiogenesis, cell migration, cell death, drug resistance, and other important topics in cancer biology.
This video documentary explains how a group of “misbehaving cells” can cause the same kinds of problems in a human body that a defective part would cause in any other item.
