Welcome to the forum - I'm sorry to read about your husband's diagnosis and know exactly what you both must be going through.
Who gave the diagnosis and have they referred your husband to an Oncologist?
I was initially diagnosed with Oesophageal Cancer by an Upper GI Surgeon who referred me on to an Oncologist and for a CT scan. I saw the Oncologist and got the CT scan results the following week. I started chemo the week after that.
The treatments offered vary depending on the exact size and location of the cancer, so it is hard to say exactly what will happen next.
Well, at least you know exactly what you are dealing with now and that it has "only" spread to one distant organ. A small positive I know, but every little helps.
