Molecular profiling is a type of genomic test that identifies abnormal gene changes that led to the development of cancer. It is part of “precision medicine” and allows for a patient’s treatment to be ultra-personalized.
During this test, the doctor will analyze the tumor (or a blood sample, called a “liquid biopsy”) at a molecular level to gain additional information about the disease, such as its stage and location.
Molecular profiling is not feasible (or useful) in all cancer cases and is not routinely offered.
