I’ve been living with a mass on my liver that is cancerous for 5 years. I decided not to have the radio embolization. I have an MRI every 6 months and so far no growth. It even shrunk 1 time. I know it sounds crazy but the procedure is invasive. I hope your friend makes it. Just pray. It can’t hurt.
Plus there is something about cancers when exposed to oxygen during surgery. Of course they can’t get every single cell. Sometimes it jumpstarts whats left into a faster growth mode.
First would be to cut out all processed sugar. If possible, all refined carbs too. Start starving the cancer that way.
