Thanks all for your feedback and support - it means a lot! In response to your questions, I am 59 and currently work in Singapore, although my home is Scotland. The healthcare in Singapore is luckily world class and I have good health cover.
I am T2c as there is cancer on both lobes - seems I have a multifocal tumour rather than a single tumour that has grown?? Perhaps thats down to family history. I understand that because of my tumour load I need treatment and AS is not an option as I have already met the criteria for intervention had I started out earlier with AS.
I will seek a second opinion from a radio oncologist as suggested. My pathology was validated already so G3 +3 it appears to be. If I do opt for Robotic Prostatectomy the pathology report may show something higher grade, I guess.
This is a great source of support and info - so glad I found you all.
