new scientific developments in medical feilds that doctors use compared to the old

1. Telemedicine: This is a rapidly growing field that allows patients and doctors to interact through new communication technologies. It can be especially useful for patients in remote areas where access to medical facilities is limited.

2. Genomic Medicine: This is a new field that uses the information from a patient's genome to guide their medical care. This can include predicting the risk of certain diseases, determining the most effective treatments, and even designing personalized treatment plans.

3. 3D Printing: Doctors are now using 3D printing to create custom prosthetics, surgical tools, and even organ models for practice before a complicated surgery. This technology has the potential to revolutionize many aspects of medical care.

4. Artificial Intelligence (AI): AI is being used in a variety of ways in the medical field, from helping to analyze medical images to predicting patient outcomes. It can help doctors make more accurate diagnoses and treatment plans.

5. Immunotherapy: This is a type of cancer treatment that uses the body's own immune system to fight cancer cells. It has shown great promise in treating certain types of cancer that were previously very difficult to treat.

6. Robotic Surgery: This allows surgeons to perform complex procedures with more precision, flexibility and control than is possible with conventional techniques. Robotic surgery is usually associated with minimally invasive surgery — procedures performed through tiny incisions.

7. Nanomedicine: The use of nanotechnology in medicine offers some exciting possibilities. Some techniques are only imagined, while others are at various stages of testing, or actually being used today. Nanotechnology in medicine involves applications of nanoparticles currently under development, as well as longer range research that involves the use of manufactured nano-robots to make repairs at the cellular level.

These are just a few examples of the many new scientific developments in the medical field. The pace of innovation is rapid, and new technologies and treatments are being developed all the time.
