Cell division, tumor growth and metastasis, 3D animation with basic narration

Description:
Cell division is essential for healthy growth of an organism and complex genetic mechanisms have evolved to switch cell division on and off at the proper time for normal development.
Transcript:
Cell division is essential for healthy growth of an organism and complex genetic mechanisms have evolved to switch cell division on and off at the proper time for normal development. Cancer happens when cells divide uncontrollably and produce a growing lump or tumor. Tumors give out chemical signals that prompt the growth of blood vessels to supply them with oxygen and food. A particularly dangerous aspect of cancer is metastasis. Here, small pieces of the tumor break off and travel through the bloodstream to invade other parts of the body.

All cancers are genetic, in that cancers are caused by genetic mutations in genes that lead to malignancy.
