If there's one place you want to make sure you understand every single word clearly, it's in the doctor's office. When it comes to comprehending, this has to be one of the most important places. After all, there's a huge difference between benign and malignant, painless or painful, trivial or life-threatening! In this lesson you'll find generic medical words that you might hear when going for a checkup or a report from a medical test. Knowing the meanings of the words can help you better decide what treatment to pursue, if any, as well as whether your reaction should be "Whew, what a relief!" or "Uh-oh. That doesn't sound too good."
