Hi and welcome,
I would agree that there are three most-important pieces information which describe your husband's case at this early phase: PSA, DRE, and Gleason sum.
For the vast majority of cases, including your husband's, DRE is reported within the "staging." DRE is an
opinion, and so it is
not uncommon for there to be some variation for the cases that are "close calls" on whether the surface of the prostate feels rough or not.
With regard to DRE, T1c simply means the prostate felt normal to one doctor. T2 means that in the opinion of the other doctor there was some roughness. T2a means a little roughness, T2b means more roughness but still only on one side, and T2c means at least some roughness on both sides.
It's also important to know that a doctor only feels one side of the prostate during a DRE exam; he/she can not feel 360-degrees around.
The fourth most-important piece of information is not often available at the time of diagnosis, and that is how the case may be changing (or not) over TIME. Most prostate cancers grow very slowly. If your husband does indeed have a palpable tumor (staged T2, based on DRE), then treatment may indeed be appropriate; if he doesn't, then maybe not (depends on other case characteristics, including how it changes over time).
Best wishes...
