moderately differentiated squamous cell carcinoma

My Wife is diagnosed with moderately differentiated keratinizing squamous cell carcinoma today.

 

We are trying to understand how serious is this , we are try to gather as much information as we can. 

Will is be bad decision to start Test & treatment after 15 days when we get back to America ?

The report just say following " infiltrating mmoderately differentiated keratinizing squamous cell carcinoma "

any kind of information will be appreciated .

 

Thanks
