Mom has lung cancer with Brain mets

My mom has been battling lung cancer for 2 years now but unfortunately treatment has not been successful. In November we found out it had metastasized to her brain, at that point there were three lesions. Tpday is was confirmed it has spread throughout the brain. She will be having radiation to try reduce the swelling and improve her quality of life. Has anyone expreinced this and could possibly tell me how much time she is likely to have left? 

  • Hi am fighting breast cancer stage 4 with spread in to my lungs.i was diagnosed in 2019 and responded well to chemo.Untill October 2020 when I had some mobility issues so I went for lung scan which showed was stable but the brain MRI showed 4 lessons in my brain.i had radiotherapy for 10 days and now on chemo tablets only.

    I am only 43 but never asked how much I left.i went back even to work.I feel fine My mobility is OK.I believe I can beat it.Because if I give up thats it Your mum needs to fight.
