I was treated for neck/head cancer in 212 after the radio and chemo treatment the lymph gland remain enlarged and the surgeon wanted to resort to surgery to remove it - just in case. My cancer consultant said we would give it two months and if it had not gone then I should prepare myself for surgery in December (212). I drank lots of Pau D'Arco tea (and still do). The lump disappeared, my MR Scans are 'totally' clear and no surgery. Draw your own conclusions, but I'm still drinking the tea.
