Good luck. I read about your tumour updates last night, and I woke up thinking about it. Must feel weird having that thing inside you, but at least you know it's just a benign fatty ball, not a malignant nasty.
I think fasting and juicing and the 80/10/10 should shrink it out of existence, with patience and persistence.
Edit- oh, I just remembered something I thought. Would it be possible for you to ask to take time off work to heal? You have a tumour after all! As you already know it shrinks when you fast, and you need time to do this... just a thought that occurred to me.
