Capitalization

I am uncertain as to whether I should capitalize the following emboldened words:

"I mean we'll go for [Unintelligible] years without turnover in other areas: in asthma, in heart disease, in cancer, diabetes; and tobacco is always changing."

The speaker is referring to specific departments/groups within an orginization, and in context they are not so generic as saying or referring to, e.g., emergency room. The above sentence is verbatim.
