<human>: Can you provide a brief rundown of the text in within 3 sentences?

My mother has stage 4 breast cancer. She had two separate mastectomies, and the cancer has spread into various parts of her body. Now it is in her cerebral and spinal fluid, which has caused her to lose ability to movement in both legs. She has been bedbound for a year now. Since she started having leg problems, we have not spared any possible test or treatment that could help her. Her case however got so bad, that chemo was hurting her more than helping. She started losing a lot of her consciousness, hallucinating, and we though we were gonna lose her a year ago from today. Now she seems to have gotten a little better on the mental side. 

Problem being, she is not aware of the intensity of her situation. She thinks its just a muscular problem, and she is demanding to see a new doctor. Her oncologists, the best 2 in the nation, both agree that there is nothing that could be done. Is it worth it for her to see a new doctor that most likely is gonna disappoint her, or should I just try to decoy her attention? It's a matter of quality over quantity here, and doctors agree that any kind of treatment is more likely to immensely reduce quality because her body is too frail. 

Mother is 65 years old, I am 23.
<bot>: mother is diagnosed with a helpless case of cancer, should i proceed attempting to get treatments even if they would hurt her physically and mentally, or should i let go?
