Medicine background with interest in Computer Science and Maths

Background:

Medicine: For 4 years, I studied medicine in Mexico, in a program that resembles very much to the US programs; I completed all the 'school phase' and 'just' had to spend 2 years more in the hospital to graduate. But I had to be honest with myself, I didn't like it very much. I couldn't stand rounding in hospitals, seeing patients, etc. I decided to drop-out under the premise that I should do what I love to do. I've also taken some extra-courses in Genetics and Molecular Diagnostics and some MOOCs in programming and research methods.

Now:

I spend most of my time reading papers in many bio~ fields and learning scientific programming, and I really love it; so I know I should do something in the intersection between medicine, computer science and genetics.

I intend to apply to as many undergraduate programs in non-mexican universities as I can, hoping to be accepted in at least one.

The Dilemma :

• Mathematics and Computer Science: I like this course because its broad application options, including biomedical sciences, and I can work in practically any field. And I have more options to pursue a masters degree than in computational biology. One thing to consider is that I have calculus certified only to Mexican high-school level, which seems to be insufficient in many countries (but I have learnt by myself a considerable amount of maths and statistics).


• Bioinformatics or Computational Biology. I like this because is more in line with my background and it would be easier for me to get accepted, and I could take advantage of what I learnt in med-school in subsequent levels.

I really like both courses and I think I would be good at both of them. The thing is which one would you recommend for having a more solid background for research purposes?

Thanks in advance...
