1. A method for detecting chromosomal abnormalities in a plurality of cells in a cervical sample, said method comprising: a) hybridizing a first nucleic acid sequence to a target nucleic acid sequence on chromosome 3q; b) hybridizing a second nucleic acid sequence to a target nucleic acid sequence on a control chromosome; c) detecting a hybridization signal of the first and the second nucleic acid sequence, wherein the hybridization signal of said first and the second nucleic acid sequences is indicative of chromosomal copy number for chromosome 3q and the control chromosome; d) scoring the chromosomal copy number for chromosome 3q; and e) reporting whether the sample contains chromosomal abnormalities, wherein a lack of chromosomal abnormalities in the sample exists when a gain of 3q copy number is in less than 0.9% of the cells.
