I would disagree with the above poster and argue that English is actually considered one of the harder/hardest languages to master. I think learning beginning Arabic will need lots of time, but we have several different people at my medical school who are trying to learn languages from scratch essentially to go to different countries during the summer, and I do go to a medical school that is considered very intensive. I put in a LOT of time to learn Arabic though and gained a solid understanding of it, and while it's highly unlikely OP will be able to do that, he can probably gain at least beginner proficiency. There are also plenty of patients who only speak Arabic or prefer it considering it is the 5th most common language in the world, we have many elderly Arabs here, many undocumented Arabs, an influx of refugees currently and over the upcoming years, etc. Arabic will definitely be very useful. Also, Egypt is considered part of the Arab world, along with countries like Somalia and North Sudan. The Egyptian Arabic that is often taught in books is not the exact same that Egyptians from lower socioeconomic classes speak amongst themselves, but the few words here and there (i.e. mish, mafeesh, etc) that OP will learn will help him to communicate a lot with Arabs from different regions.
