Hi, I understand your frustration as my dad is recently diagnosed with stage four bladder cancer. He never smoked a pack in cigarettes his entire life but spent many years working in a toxic nail shop to support a living for his family.
Anyways, I recently came across some cancer fighting herbal tea while surfing the net for some answers and they're called, Pau d'Arco, Ojibway tea and Essiac tea. I have done only internet research and probably it is worth trying. I just ordered a bag of the tea for my dad and hopefully it will make a difference. I would also advise you to do your own research on the tea's effectivenss bc it is your loved one and your decision.
Again, I truly understand what you are going through and we're all in this together as one big family. I pray for my dad and the sick every day. Please be strong and don't lose hope. I truly hope this tea is a miracle and if it is, please pass it on.
God bless, manicurist79
