ApplyTexas Common App - can I write about a medical phenomenon?

Hi, I am currently writing my ApplyTexas essay B which is..

Topic B: Choose an issue of importance to you-the issue could be personal, school related, local, political, or international in scope-and write an essay in which you explain the significance of that issue to yourself, your family, your community, or your generation.

My question is that can I write about a medical phenomenon that will have implications to everyone in the future, for example stem cell research or something along those lines?

Yes, of 'course you can write about stem cell research because it is a very controversial issue. My friend actually chose that as an issue to speak about during her Physician Assistant interview and she got in. Good luck to you!

Just make sure it is not too controversial. Though it may make for an interesting essay, you do not know what the admissions officer's views are--- thus, this could hurt your chances of getting in. This is why I have been advised to stay away from subjects that are very controversial. Good luck and if you can look over my essays that I posted on this forum, that would be great.
