Gosh I just posted as a newbie. What a story you have. I too am 67yrs old and am about to have all the lymph nodes out, similar to your story
I am pooping myself....
However this is not about me, you so deserve to live.... Yep this is shite... a bit of a blip in our lives but we will get through this. You are only 67.... I have not seen the oncologist yet, but the surgeon was organising it prior to surgery. I think it is best to put out the spot fires now before a bushfire happens....
Young, fit and healthy, well apart from a few intruders... and the occasional wine and chocolate.
Big hugs, we have this.......
