Hi Marta,
I'm so sorry to hear about your diagnosis. You are most certainly in the right place though.
I too was diagnosed with SCC in my tongue. It was HPV negative. I had surgery followed by chemoradiotherapy, plus immunotherapy.

It's a difficult journey, but one where you are supported thoroughly by members on here. No question is a bad question , but do take time to go through the boards to see previous discussions and advice.

Be well and take care
