If you are wanting lists of medical words in English I would recommend taking a look at the National Library of Medicine's Medical Subject Headings (Mesh) thesaurus. Other useful tools include RxNorm (related to US pharmaceuticals) or Snowmed-Ct which is a medical ontology for multiple languages.

I've really benifited from others mentioning resources like these here on HN so I thought I would share.
