Cavalli and her team 1st screened the genomes of cells from both tumors and nodes from the same patient using comparative genome hybridization , and discovered that most of the genomic areas affected were very similar in both of the samples. Then they used microarray technology to identify the genes modified in these regions and found several which were altered in patient lymph nodes and tumors.
