No smoking for me for 37 years before DX.....no
HPV (insisted on being tested)..and no betel nuts either.
I wish that you could contact your dr. with your concerns and ask for a PET/CT several days before your surgery. Isn't your surgery to take place THIS Friday?
I wouldn't be comfortable going into surgery without a bit more clarity about what my problem is.
The PET/CT is a full-body scan, and it is wonderfully reassuring.
