I have a slightly different understanding about metastasis from Darrell. I always think that T refers to the tumor size at the primary site while N stands for the size of tumors of lymph nodes metastasis while M refers to the distant spread to other organs like lung or liver. In Edgar's case, I think his tumor is not confined to the primary site if it is N1. Just hope that some knowledgeable posters here can clarify this.
Anyway, all the best to your treatment and I'm sure you can go through it just like most of us here, Edgar.
