There are dozens of medical-related majors, spanning everything from pre-med biology to nursing, pharmacy, public health, and biomedical engineering. The right one depends on whether you want to treat patients directly, work behind the scenes in a lab, manage healthcare organizations, or design medical technology. Here’s a clear breakdown of the major pathways.
Pre-Med Undergraduate Majors
“Pre-med” isn’t a single major. It’s a track you follow alongside whatever undergraduate degree you choose, making sure you complete the science prerequisites that medical schools require. Among students who entered U.S. medical schools in 2024, the most popular undergraduate major was biological sciences (13,420 students), followed by physical sciences like chemistry and physics (2,121), social sciences such as psychology and sociology (2,040), humanities (785), and math and statistics (172). Another 3,616 fell into an “other” category, covering everything from engineering to music.
The takeaway: you can major in almost anything and still get into medical school, as long as you complete the required coursework in biology, chemistry, organic chemistry, physics, and math. The same is true for veterinary school. The American Veterinary Medical Association notes that vet students come from backgrounds including English, engineering, and math. What matters is completing prerequisites and performing well in them, not the name on your diploma.
Physician Degrees: MD and DO
If your goal is to become a doctor in the United States, you’ll pursue either a Doctor of Medicine (MD) or a Doctor of Osteopathic Medicine (DO). Both lead to full medical licensure, residency training, and the ability to practice in any specialty.
The MD path typically means four years of undergraduate study followed by four years of medical school. The first two years focus on classroom-based sciences like anatomy, pharmacology, and pathology. The final two years are clinical rotations in hospitals, where you cycle through surgery, internal medicine, pediatrics, psychiatry, and other specialties. After graduating, you complete a residency lasting three to seven years depending on your chosen specialty, then pass a final licensing exam.
DO programs follow a similar structure but include additional training in osteopathic manipulative medicine, a hands-on approach to diagnosing and treating musculoskeletal issues. MD and DO graduates take different licensing exams but apply to the same residency programs and practice side by side in every specialty.
Outside North America, the equivalent degree is the MBBS (Bachelor of Medicine and Bachelor of Surgery), common in the UK, India, Australia, and many other countries. It’s typically a five- to six-year undergraduate program entered directly after high school, with a built-in 12-month internship. MBBS holders who want to practice in the U.S. must pass additional licensing exams and complete a U.S. residency.
Nursing Degrees
Nursing offers one of the most flexible educational ladders in healthcare, with entry points at several levels.
- Associate Degree in Nursing (ADN): A two- to three-year program, often at a community college, that qualifies you to sit for the registered nurse (RN) licensing exam. This is the fastest route to becoming an RN.
- Bachelor of Science in Nursing (BSN): A four-year university degree that also leads to RN licensure but opens more doors for hospital positions, leadership roles, and graduate study. Many employers now prefer or require a BSN.
- Master of Science in Nursing (MSN): A 1.5- to 2-year graduate program that prepares RNs for advanced practice roles, including nurse practitioner, nurse midwife, nurse anesthetist, and clinical nurse specialist. Nurse practitioners can diagnose conditions, prescribe medications, and in many states practice independently.
- Doctor of Nursing Practice (DNP): The highest clinical nursing degree, focused on leadership and advanced patient care. More programs are moving toward the DNP as the standard for nurse practitioners.
Pharmacy, Dentistry, and Veterinary Medicine
These are professional doctoral programs, each requiring undergraduate prerequisite coursework before admission.
Pharmacy students earn a Doctor of Pharmacy (PharmD), typically a four-year graduate program focused on how drugs work in the body, drug interactions, dosing, and patient counseling. Pharmacists work in retail pharmacies, hospitals, research labs, and the pharmaceutical industry.
Dental students earn either a Doctor of Dental Surgery (DDS) or Doctor of Dental Medicine (DMD). The two degrees are functionally identical, just named differently by different schools. Dental school lasts four years and covers oral anatomy, radiology, restorative procedures, and clinical rotations where students treat patients under supervision.
Veterinary students earn a Doctor of Veterinary Medicine (DVM) through a four-year program. Recommended undergraduate coursework includes anatomy, physiology, microbiology, animal science, nutrition, and histology, though each school sets its own specific prerequisites. Like medical residencies, veterinary graduates can specialize further in areas like surgery, oncology, or emergency medicine.
Allied Health Majors
Allied health is a broad category covering the clinical professionals who aren’t doctors or nurses but play essential roles in diagnosis and treatment. These majors lead to hands-on careers, often with a bachelor’s degree or less.
Respiratory therapy programs award a bachelor’s degree and prepare graduates to treat patients of all ages with breathing difficulties, from premature infants with underdeveloped lungs to older adults with chronic lung disease. Respiratory therapists work under physician supervision in hospitals, ICUs, and home health settings.
Radiologic technology (sometimes called medical imaging) trains students to perform X-rays, CT scans, MRIs, and other diagnostic imaging. Most programs are two to four years and require passing a certification exam. Physical therapy requires a Doctor of Physical Therapy (DPT), a three-year graduate program after completing an undergraduate degree. Occupational therapy requires a master’s or doctoral degree.
Clinical laboratory science (also called medical technology) focuses on analyzing blood, tissue, and other samples to help physicians diagnose diseases. These programs are typically four-year bachelor’s degrees, and graduates work in hospital labs, reference laboratories, and research facilities.
Public Health and Health Administration
Not every medical major involves direct patient care. Public health and health administration focus on the systems that keep populations healthy and healthcare organizations running.
A Bachelor of Science in Public Health covers epidemiology (how diseases spread through populations), biostatistics, health policy, and community health. Coursework at schools like UNC Chapel Hill includes statistics, biology, economics, and a required internship. Graduates work at government agencies, nonprofits, consulting firms, hospitals, health insurance companies, and research organizations. Within two to five years, the majority go on to pursue a graduate degree in public health or medicine.
Health administration (sometimes called health management or health services administration) prepares students to run the business side of healthcare. Core coursework includes health law and ethics, financial management, strategic planning, health information technology, and organizational leadership. These graduates become hospital administrators, clinic managers, health policy analysts, and insurance executives.
At the graduate level, a Master of Public Health (MPH) is the standard degree for public health professionals, while a Master of Health Administration (MHA) targets those aiming for executive leadership in hospitals and health systems.
Biomedical Engineering and Health Informatics
These majors sit at the intersection of medicine and technology. Biomedical engineering applies engineering principles to healthcare problems: designing prosthetics, building medical devices, developing drug delivery systems, and creating tissue-engineered implants. It’s a four-year undergraduate degree combining coursework in engineering, biology, chemistry, and physics, with many graduates continuing to master’s or doctoral programs.
Health informatics focuses on how health data is collected, stored, analyzed, and used to improve care. The field covers everything from electronic medical records and clinical decision-support tools to artificial intelligence systems that analyze large biomedical datasets. Informatics professionals help hospitals manage patient data, build tools for early disease detection, and develop systems that deliver personalized treatment recommendations to doctors and patients. Programs exist at the bachelor’s, master’s, and doctoral levels, and graduates work in hospitals, tech companies, government agencies, and health startups.
Choosing Based on Your Goals
The “right” medical major depends entirely on what kind of work energizes you. If you want to diagnose and treat patients, you’re looking at MD, DO, or nurse practitioner pathways. If you want a clinical role with a shorter educational timeline, allied health fields like respiratory therapy or radiologic technology get you into patient care in two to four years. If you’re drawn to science but not necessarily patient interaction, clinical laboratory science or biomedical engineering might be a better fit. And if you’re interested in shaping healthcare at the organizational or population level, public health and health administration let you do that without ever picking up a stethoscope.
For salary context, primary care physicians in the U.S. earned an average of $287,000 in 2024, while specialists averaged $404,000. Nurse practitioners, pharmacists, and physical therapists typically earn between $90,000 and $130,000, and allied health professionals range widely depending on the field and location. The investment in education, both time and money, scales accordingly.
