Thanks for your question on HCM.
I can understand your situation and problem.
But, honestly speaking stage4
liver cancer is incurable and there is no definite treatment for cure.
So I advice you not to take Brazil nuts. It will not help you further.
Instead of all these,you should start palliative treatment in the form of
1. Pain treatment like centrally acting pain killers (opioids)
2. Nutritional support in the form of supplemental iron,
vitamins, calories,carbohydrates, protein etc.
3.
Consult psychiatrist and discuss end of life issues.
These will help you more.
