I've read your journey about your mom. I'm sorry you and your family have to go through this - it's so hard and scary at the same time. But I am happy you are here. This network is so helpful and kind, and I am sure you will find incredible support.
If you don't mind, I am going to suggest you rephrase your question. I think people will come here and tell you that there is always hope. But...if you are seeking specific recommendations, you might want to ask a specific question.
"Is there any other treatment we should ask the doctor about? My mother has high level sarcoma cancer uterus and vaginal cancer. They are currently treating her with XYZ. Is there any other treatment that we should be asking about?"
Additionally, (and you may have done this) you may want to search (on the "People" page) for others with a similar diagnosis (on the far left of the page you can narrow your search). Then, you can read through their journeys and see what decisions they made, and/or you can reach out to them and tell them your mom's situation and see if they have any meaningful insight they can share.
I hope this helps you to get some actionable recommendations and support. Please know we are here for you and want to help you in any way we can.
