@RedRosesPinkLilies oncologists are a law unto themselves! I've learnt not to pay too much heed to how enthusiastic/pessimistic they are, I think it just depends on their nature.
As a case in point I had scans for brachytherapy. My main oncologist was like yeah, things seem to be heading in the right direction, there's been some reduction etc etc. I left quite concerned that they were improving but not quickly enough...
Next week I saw another oncologist as mine was on holiday and after looking at the same set of scans she was 'ooh, these scans are looking fantastic, great reduction, only residual left in the lymph nodes and the main tumour is shrinking nicely too, it's looking really good'.
It honestly felt like they were looking at two different sets of scans and both were factually correct in what they told me but the manner was definitely different.
I suppose it's a double edged sword - cancer is so unpredictable that you don't want to give people false hope that everything is definitely going to be fine. On the other hand I much preferred the second oncologists outlook!
