Ash444 Hey, that’s fine too! Ultimately the forum is for helping students like you out and the more we get to know what you want in your career, the better we can answer your original post, but you only need to share what you want to divulge. Since it appears to be personal, we can leave it at that. 🙂
In that case, you’re looking at careers with a mix of neurology, oncology and bioengineering. You also want to help people, to travel, to have spare time to do your boxing training/ be a pro boxer. Most of the things I’ve specified before are potential ideas for you. I’d also put out there the idea of medical/ bioengineering research, specialising in brain cancer, but this is lower down the list compared to most other careers I’ve listed, or biomedical engineering or medical engineering as Jinx and _Sophiestudies _ have said, which combine both areas.
Now to link back to your med vs. eng problem. With all your posts, I think you could do either.
Medicine would take longer to specialise and have less free time, as stated already. Engineering wouldn’t take as long and give you more spare time to go into boxing, but it will become harder to get into some of these fields.
In the end, the choice is yours and remember that there’s multiple pathways to get where you want.
