How did your mum get on? I know what you are going through my mum has just started treatment after being diagnosed with secondary breast cancer to the bones, liver and pleura. My mum has just started her chemotheapy treatment today and her oncologist and nurses were all very positive. When she was initially diagnosed I was in shock and I thought the worst but the treatments they can offer have come along way and I advise you to read some of the inspiring stories on here.
Although she is having treatment I feel angry and low people don't seem to understand. I live 3 hours away from my mum and although she has got my dad I feel guilty leaving her and not being able to be there to look after her all of the time. As for support this is a great place to start people your not alone anytime your finding things hard drop me a message.
Im so sorry, this is what im dreading the most, my mum is only 3 years out and it terrifies me... I hope she gets good results from the scans and that it is again treatable maybe even curable this time. Treatment has come a long way in 16 years so don't worry until you have to.
Wish you and your mum the best of luck xxxxxxx
