Sorry for your troubles, but welcome. The pathology report from your surgery, plus surgery report should say if you had positive or close margins, so you may want to look at that, plus it has other information too. PET scans can show false positive from scar tissue, swelling, and doesn't prove cancer, only a direct biopsy, FNAB or other biopsy can, plus has other info. It's not true about no test for men. They can still do a HPV DNA test on any tissue samples taken for biopsy, if frozen, but what David said is true, and may not have been tested, maybe you were? You may want to know since it effects prognosis being you are interested in stats, and being HPV positive shows improvement in treatment, and prognosis by 20 percent, if not more by recent data. Most recurrences for SCCHN ocurr the first two years, probably the first year is higher, but that's a general average, and does not include other information which can make a difference in prognosis. Two things that greatly effect prognosis is tumor size, and nodal involvement, and see nothing about nodes in your post, but again, other factors are involved. Otherwise, it sounds like you are doing well in your revovery, and should look forward to a clear scan.
