In the past 30 years it has changed a huge amount. A few examples: imagining - MRIs were being developed in the 80s and not available for diagnostic use, now they are common place; much much better CT scanners than anything available 30 years ago, medical implants like pacemakers and defibrillators have a evolved a lot in that time, cancer treatment and life expectancy for most types of cancers are not even similar to what was going on 30 years ago. I could go on :P
