ploidy

[ploy-dee] number of sets of chromosomes contained in a cell. Ploidy can sometimes help predict how quickly a cancer is likely to spread. Cancer cells with 23 pairs of chromosomes (the same as as normal cells) are called diploid (dip-loyd) and those with either more or less than that amount are aneuploid (an-you-ployd). See also chromosome, deoxyribonucleic acid.
