Cell: What are Cancer Cells?

Cancer cells differ from normal cells in three aspects:
1.      abnormal nuclei
2.      lack of differentiation, and
3.      abnormal cell division
Cancer cells have enlarged nuclei, which means that there may be an abnormal number of chromosomes.  The chromosomes exhibit mutant characteristics such as deletion or duplication of some parts.  Extra copies of genes may also be observed.
