I beg to differ. From what I understand, Tumors are kept for years at hospitals, but not frozen, rather paraffin embedded. This allows it to be tested with oncodx, for her2 pten and other IHC and rna based tests but not with microgene array and other dna based tests as I understand it.

For those who are having your primary or mets biopsied now--ask to have a small amount of it fresh frozen as that will allow the cutting edge microgene array based tests to be performed on it as knowledge advances in the (hopefully) not so distant future.
