S0 sorry your Onc isn't really addressing your concerns re your diagnosis & treatment .... my first Onc was 'similar' - dismissing my concerns - I was very lucky that a 2nd Onc had just joined the Public Hospital that I attend (and MY Rad Onc had thoroughly recommended her as well ....) so when my first Onc was away on leave, I saw HER - and have continued to see her for 4 years+ now too.
It is Definitely not too late to change Oncs ..... maybe just message your Breast Care Nurse (if you have their Mobile No/email address) - then she can get back to you in her own time .....
What area are you in (roughly)? (You can add it to your Profile & Members may be able to point you to someone specifically in your area, via Personal Message.) If your area has a cancer centre/public hospital, you should be able to google them & see who else works there as an Onc ..... or also ask your Rad Onc - they will be VERY aware of any other Medical Oncs in the area - and it seems your Rad Onc is definitely 'in your corner' for you xx
You really shouldn't have to be chasing the Onc for preferred treatment/diagnostic tools - THEY should be suggesting all that for YOU! xx.
Take care & all the best
