Is the brain tumor cured?

Can you make a small mistake about Fu CuO's brain tumor? Fu CuO's illness in the story is a brain tumor, and the initial symptom is nosebleeds. I once thought it was leukemia, because I knew the ending of the story before reading it, and the hope of curing leukemia was quite great, but I didn't expect the word brain tumor to appear in the end. I saw a record post of a young man with a brain tumor in Zhihu. Seriously, the reality is cruel. A person who was able to run and walk a few days ago may be bedridden after the onset, with blurred vision, hearing loss, severe headache and psychological struggle and struggle with the disease. In contrast, the novel is really kind and fairy tale. The answer is for reference only.
