Pole sana. How I wish I was a neurologist to be able to address your question scientifically. My heart goes out to you.
Have you considered/done, in addition to conventional treatment, anything ie dietwise, herbs, supplements to help fight the cancer?
I had a chance chat with a certain lady yesterday, who's relative got healed of cancer. Said they opted for treatment in India. Something about specialization and superior equipment. She also mentioned a cancer patient had approached her for pawpaw grains(she has pawpaw trees). Hemp oil?
