Hi, I have a general question that puzzles me. Why do some H&N cancers spread to the nodes and some don't? I've noticed on the forum that even people with T3&T4 tumors will not have node involvement, while smaller primaries T1-T2 will have node involvement. Richard's is a small primary T1 about a 1/2 inch in size, but 1 node about an inch from the primary is involved. Does location matter or is this simply one more unanswered question about cancer? Thanks for any thoughts on the subject. Geri
