I begged my friend of 50 years to try dog wormer, she was diagnosed with a brain tumour last Christmas. She was on CBD oil and chose to stay with it, and it appeared to work. Tumour stopped growing and started responding to treatment Last week she was told her tumour had spread further and was now going deeper into her brain. I'm back to begging her to try it now she has nothing to lose, tho I feel it may be too late.
