Do the cancer cells have a normal number of chromosomes?
Doctors also use ploidy, a measurement of the number of chromosomes present in cancer cells, to determine how fast a tumor may be growing: • Diploid cancer cells have a normal number of chromosomes. • Aneuploid cells have more chromosomes than normal, because they are growing faster than normal cells and need extra genetic material to pass on to the new cells they make. • Diploid cancers have more favorable outcomes than aneuploid cancers. But ploidy is just one factor in the grand scheme of cancer personality. This feature on its own does not have a major impact on your outcome.
