Hi, I'm new here and just struggling to come to terms with everything my mum was diagnosed with metastatic breast cancer last year, we were told a few weeks ago it's now in her brain, and is leptomeningeal disease. She started chemo, but was taken off it yesterday an now the only option is whole brain radiotherapy. I'm so worried/scared to see her go through that and not sure what to expect, I know the prognosis isn't good . She's already becoming forgetful, paranoid and her personality is changing. It's so hard seeing this change her
