Secondary cancer in brain

Hi everyone,

My mum has had breast cancer 3 times over the last few years, and unfortunately, they've now found a lesion in her brain that they think has travelled from her breast.

They are looking into the option of surgery or stereotactic radiotherapy, but have said they aren't treating to cure.

Has anyone else had experience of this situation? How long mum has of course depends on how she responds to treatment, but I'm just hoping to hear some people's experiences of this kind of radiotherapy, and how effective it could be. I've heard some people can live with a brain tumour for years so staying hopeful.

Thanks x

  • Hi  

    I am sorry your mum has breast cancer that has travelled to her brain. Although I have secondary breast cancer, I don’t have this exact experience as mine travelled to my liver. It’s quite usual for doctors to say they aren’t treating secondary cancer to cure it. Once it has travelled from the breast to somewhere else, cancer has been in either the lymph system or the blood system, so microscopic cancer cells that can’t be seen on a scan could be elsewhere. Treatment usually aims to keep the cancer, and the side effects of the cancer under control. It’s good your mum may be a candidate for some localised surgery or stereotactic radiotherapy. I was similarly able to have some localised treatment in my liver, which was helpful. I hope someone with experience of these treatments comes along; you also might want to consider adding your question to our main Breast cancer forum  as there may be some people with experience there.

  • Hi Ellz

    well done for coming here to talk about your mums recent prognosis. I hope you are both managing h after the shock of being told . It can be such devastating news. Sending you all a hug.

    I also have a secondary breast cancer that has caused 3 tumours to be found in my brain. Just 1 yr after breast cancer with lumpectomy surgery. I’ve just completed  the treatment to you mentioned. I am 63 & was diagnosed Feb 2026. I had a craniotomy to remove a large tumour and then steriotatic (radiotherapy) on 2 smaller tumours. This was followed quite quickly with 6 cycles of chemo and Phesgo  injections. I’m due to have scans every 3 mths as it’s likely to have traveled in my blood. I’m feeling lucky as I don’t feel particularly unwell . Touch wood. I’m just waiting for my first post treatment scan results. I urge your mum to remain  positive she cleat has a wonderful daughter and has treatment t options . Today I went for a sea swim with my 30 yr old son and daughter and my 3 little grandchildren. 
    life is still great despite my prognosis. All my best to you. 

  • Thank you for your reply, I really appreciate it. It's so positive that you've had some treatment to your liver and it's been successful, modern medicine is incredible. Sending you lots of strength and well wishes xx

  • Thank you for sharing your experience, it really means a lot especially with everything you are going through yourself. That sea swim sounds amazing, so happy to hear you are feeling well and spending time with your family xx

  • Hi Ellz

    Sorry your mum is going through this. If it helps, my brain mets were diagnosed in March 2024 and I’m still here.

    I haven’t had stereotactic radiotherapy but I have had chemo, phesgo, regional radiotherapy and brain surgery.
