quality for decades.
By offering a standardised approach to
biospecimen collection and archiving, our
mission is to accelerate cancer research
and drive the development of precision
medicine. Through the power of linking
cancer samples with comprehensive patient
information, we can pave the way for more
effective, targeted, and less toxic therapies.
Currently the RVC Cancer Biobank
contains samples from a total of 69 different
cancer types. Although we are collecting
samples from all cancer types, we have
a particular interest in the collection of
endocrine cancers, as this is one of the
focus areas of RVC researchers.

the obstruction, a proportion of cats will be left with chronic kidney disease. The
factors involved in kidney recovery after a sudden injury are currently poorly
understood and it is challenging to identify patients who will go on to suffer from
ongoing renal dysfunction. How and when to intervene to encourage complete
renal recovery after injury is also unclear. The biobank stores residual samples
