Has your cancer been staged? Apart from my husband (in situ), Jane's (Lostpassword) husband (in situ or Stage 1) and Jerry Wilck (wilckdds, Stage 1), I can't think of very many folks here who did NOT have radiation.
Jane has explained her husband's situation above. You could do a search on Jerry's posts -- choose "Advanced" in the search box in the upper right to enable the search for a keyword AND a user name -- to see if he talks about not having radiation, or you could send him a e-mail or a private message to ask why he didn't (or whether it was even offered).
