Have to disagree here, chemo and radiotherapy simply destroy everything, they are a killer in their own right, they are simply a barbaric and dangerous protocol. Nobody would freely consume either without falling seriously ill but you can take cbd oil any time, any day. There have been many testimonials of tumours not continuing to increase in size once cbd oil is consumed and unless they've altered something else within their lifestyle then it's benefiting their case.
Edit: tumours and cancer aren't synonymous, not all tumour cells are cancerous.
