Breast cancer mets in kidney

Hi ladies, it’s my first post on this website. Just wanted to ask if any of you experienced kidney mets from breast cancer? My mum had locally advanced breast cancer in 2015, aged 52, everything was fine, she felt great and we all started getting our life back to normal, very suddenly in Feb 2019 she developed sypmtoms of a stroke, we took mum to hospital and CT scan revieled the worst - tumor in her brain… the very same day she had MRI scan which showed  a spot on her lung and left kidney… as you all can imagine we are absolutely devastated, awaiting brain surgery to remove the tumor. But what I would like to ask you, has any of you dealt with kidney mets? I think it’s very rare to get bc mets in the kidney, personally I’ve never came across anyone with bc which spread to kidney, as we now have diagnosis that brain tumor indeed is bc, I’m very worried that  kidney has nothing to do with breast cancer and it actually is a new primary , on top of metastatic breast cancer. 

 

Sorry for long post, and thank you for reading.  

 

I was told after a CT scan that I had kidney “spots”.  An ultrasound was arranged and my kidneys are fine.  Might be worth asking for one.
