The answer to your question is, yes. There is a way to speed the process up.
1. One way is by doing a joint M.D./ Ph.D degree program. Only a few places offer this program.
2. Another way would be to do an accelerated Ph.D. This is not only rare but also hard. Typically, a Ph.D degree takes about 5-8 years to get. But depending on the topic of research and the total time and effort put in, it can be done in 4 years. I even know someone who did it in 3.5 years (super rare)
3. A third way can be during a surgical residency. Certain surgical residency programs offer the option to pursue a Ph.D which may save some more time.
