Shоrt Essаy Questiоn (100-200 wоrds, 8-12 sentences, 1-2 pаrаgraphs) Cancer diagnosis and treatments have traditionally been organ-based in the past in regards to diagnosis and a one-size-fits-all approach to treatment. For the last two decades, the paradigm has slowly been shifting towards a more science-driven approach based on a better understanding of the etiological basis of various cancers. From a testing standpoint, what is the class of analytes called which has been driving this paradigm shift? What is the new paradigm/approach that has started in the past few decades? (Hint: __________ medicine). How has this new testing and treatment paradigm impacted the management of cancer (and even other diseases)? Provide two or more examples of specific diseases or cancers that have been impacted by this new paradigm. For each example, please describe: i) what specific cancer/disease marker the new approach tests for, and ii) how it is an improvement over organ-based decision-making for treatments.
