Aneuploidy has long been recognized to be a cardinal feature of many neoplasias. However, the role of aneuploidy in tumorigenesis continues to be a matter of debate.

Here we discuss our definition of chromosomal instability, evidence for its causal role in tumor development, and suggestions regarding the mechanisms that initiate chromosomal instability in cancer cells.
