Index of Diseases

Instructions. To find the proper medical term, scroll up and down to review the alphabetical listings. Also, you can use the "Page Up" and "Page down" key on your keyboard. Or use the search function of your browser. In both Netscape and Explorer, go to "Edit" and select "Find in Page". Type in the main term of interest. Frequently, it is best to type in only the first 4 or five letters (i.e., "prost" for prostate) because that will find more alternative terms from which to select the proper one.
