Medical term meaning.

It's a term to describe epithelium....skin basicallyt

The skin lining your mouth and throat is basically the same as the skin on the your body. It's made the same but your outer layer has to be tough so the cells lose their nucleus and become flat and hard and full of keratin so they are basically dead. 

The skin lining your mouth and intestine has to remain pliable and moist. So the cells retain their nuclei, their plump living shape with no hard keratin  

It's not a pathological change but purely a descriptive one

SCC is squamous cell carcinoma ....a cancer of those cells lining the mouth which are squamous cells....epithelial cells

So that’s nothing concerning?

In what way? 
It just describes the histological appearance of the cancer. 
if you mean does it indicate a poor prognosis then no.
