Tom,
I would highly recommend you go for the adjucant treatment plan. To put it simply, my husband had stage 1 cancer 5 years ago , had surgery and no chemo follow up. He had a recurrence a little over 2 years ago and passed away last month. At the very same time, we had a friend that also had surgery ,she had the chemo... she is now 5 years out and NED. At that time , it was not known if it would make a difference , but it is my belief that it is becoming more and more evident that it does. If at all possible , I would say , give yourself every chance. The chemo may be a little rough, but if my husband had been able to do it over again, he would have had it. God Bless.
