Molecular medicine is a field of medical science that focuses on understanding diseases at the molecular level. It involves studying the interactions between genes, proteins, and other molecules to identify the underlying causes of illnesses. This knowledge helps in developing targeted therapies and personalized treatments for various conditions, including cancer and genetic disorders. Researchers in molecular medicine often use techniques from genetics, biochemistry, and cell biology to explore how molecular changes affect health. By analyzing the molecular mechanisms of diseases, scientists aim to create more effective diagnostic tools and innovative treatments, ultimately improving patient care and outcomes.
