Defining Medicine
Medicine is a science, but it is also an art that involves the complex interplay of integrative modes of study, clinical experience, and, as always, compassion for the patient. It cuts across disciplines such as internal medicine, surgery, pediatrics, psychiatry, and public health, tapping into fields like anatomy, pharmacology, and epidemiology. In recorded history, medicine has gone from ancient people using herbal mixtures to heal wounded friends or family (like the Egyptian Ebers Papyrus around 1550 BC) through game changers, including the discovery of penicillin in 1928 and the completion of The Human Genome Project in 2003. Well, today medicine uses artificial intelligence, genomics, and telemedicine to provide accessible, personalized care. The world market for medical research is expected to grow to $350bn by 2030. The projected push on biotech and digital health investment reflects the rising importance of medicine as a proactive defence against health threats.
