Language of Cancer:
A mini-dictionary of terms relating to cancer

"Antipyretic. A-N-T-I-P-Y-R-E-T-I-C. Antipyretic."
With that one word, meaning a drug that reduces fever, Joanne Lagatta, of Madison, Wis., won the 1991 National Spelling Bee.

The vocabulary of cancer is also full of big, intimidating words that rarely crop up in everyday language. But the potential rewards of learning -- and understanding -- these words are much greater for people who are seeking the best treatment for their cancer. The most recent National Assessment of Adult Literacy found that only 12% of Americans could be considered proficient in understanding health information. So we put together a highly abbreviated glossary of common cancer terms. If you need more help understanding your diagnosis, talk to your health-care team or visit the Patient Education Resource Center on Level B-1 for more resources.

And don't worry: We won't quiz you on spelling.
