Sparkly, I think it’s great that you want to do research to help cure cancer. But you should realize that pharmacists don’t do research- they dispense the medicines that other people have developed and tested. If you really want to do research, whether clinical or basic science, then you should consider a slightly different track- continue taking science courses at the undergrad level as you are doing, and then you would have to do a PhD program in biology, or maybe medicinal chemistry, but since you said you don’t like chemistry, I would think a biology track would be better. With an MsC, you can get a job in a drug company, for example, but you won’t be doing much- more technical work. You would need a PhD to do any real research- either in academia or in biotech/pharma. Or, to make things harder, an MD/PhD if you really want to do clinical cancer research.
I know all about this because once-upon-a-time I also considered being a pharmacist as a practical profession, but then realized that I really could not see myself standing all day putting pills in bottle. I also really wanted to do research, especially in drug action, so then I considered pharmacology, which eventually led me to my current field. I work for a basic biology lab that studies tumor suppressors and other processes involved in cancer. I/we have not found a cure for cancer, nor do we expect to, but we have contributed to the body of knowledge to help us understand how cancer and other diseases develop.
And by the way, long hair, even in a pony, in a lab is a hazard, you would need to put it up! (see, this wasn’t off topic afterall)
Long hair will also be problematic when you are married, both for being able to cover it adequately, and for mikve. Since you want to be married soon, you might want to get used to the idea of parting with the long hair.
