Apparently you did some online research and said that "Google tells a different story" as compared to your surgeon, right?
Your Oncologist told you, "Some people don't opt for chemo but didn't recommend that". I'm shocked.
But prior to that, your surgeon said to you that your "cancer is all gone". So why didn't you run with that and seek an alternate plan to chemo ?
The destruction done to one's health by chemo should be taken seriously and in my opinion, avoided at all cost, at least until cancer returns as seen in blood tests and CT Scans every 90 days.
A lot of people begin chemo at a time where no cancer is evident. Especially under that circumstance, for me, chemo is a hard sell.
Again, best wishes to you in your journey !
