"Molecular diagnostics” is another term that you may never have heard of before your cancer diagnosis. Since it's difficult to discuss personalized medicine without talking about molecular diagnostics, we have an entire section on the topic. We will therefore discuss the meaning of ”molecular diagnostics” and how it may affect your treatment choices.
Simply put, molecular diagnostics includes all tests and methods used to identify a disease or the likelihood of developing a specific disease by analyzing biomarkers (DNA, RNA, or proteins).
Once particular biomarkers are identified using a molecular diagnostic, your doctor could learn important information about the biology of your cancer, helping him determine treatment decisions specific to your case.
Right now biomarkers that can be matched to targeted treatments have not yet been identified and validated for all cancer types. But, research is ongoing to detect such markers and to introduce additional successful targeted therapies for different cancers.
