Leslie pointed out to me that we don't cover grading very well so here you have it:
The definitions of the G categories apply to all head and neck sites except thyroid. These are:
G - Histopathological Grading
GX. Grade of differentiation cannot be assessed
G1. Well differentiated
G2. Moderately differentiated
G3. Poorly differentiated
G4. Undifferentiated
Differentiation: In cancer, refers to how mature (developed) the cancer cells are in a tumor. Differentiated tumor cells resemble normal cells and tend to grow and spread at a slower rate than undifferentiated or poorly differentiated tumor cells, which lack the structure and function of normal cells and grow uncontrollably.
In other words, poorly differentiated tumors can or will cross all boundaries of tissue types (muscle, soft tissue, etc.), even into bone.
All of these factors are taken into consideration for your treatment plan.
Another term they like to use is how "invasive" it is - like "focally invasive" for instance.
Focal: In terms of cancer, limited to a specific area.
You and I have basically the same Dx with the exception that mine was "moderately well differentiated" and my tumor was much larger (T3).
I would recomend bringing a good note taker with you each time you see the doctor. They cover a lot in a short time period and you will have to make many decisions very quickly.
It's great that you want to be your own advocate and we highly encourage that. We are here to help in any way we can. It's sounds like they caught it at a very early stage and that is a good thing as well.
