Hi... I'm kinda in the same boat although I was very upset when I found about about my mum but now 2 months later my mind has seemed to shut off from the hole thing and I fill I'm kinda in denial.... my mum was diagnosed finally in october where like your mum she started the hormone treatment only she had a scan in January to find out it was having no effect and was still spreading... my mum has stage 4 breast cancer and its already spread to her bones like your mum, my mum is at risk of it spreading further to her liver lungs or brain there is no answers!!!... after finding out the hormone treatment wasnt working my mum has now started chemo paclitaxel iv been told theres 100s of chemotherapy options out there so your mums consultant should b able come up with the best option... unfortunately I'm left with the same question I have no idea on life expectancy iv googled and searched many sites and seen no longer than 5 years for breast cancer that's metalized I'm not sure on this and unsure who I can turn to to kno the full truth. Hope some of this helps.

Hi both of you, Only your mums' doctors can answer questions like this, because every individual cancer is different. 

If your mums agree in advance, you can ask their doctors any questions you want. Your mums may not want this, of course. Or they may not want to know themselves, but have no objection to you knowing.

Really tough times for both of you, I wish you the very best.
