My mom had a cancerous nodule in her lung that the drs wanted to surgically remove.
However, I was able to get nearly all of her lung nodules, including the spiculed, cancerous one, to shrink 4mm in just 3 months.
I attribute it to the vitamin D and serrapeptase.
Her renal cyst also, shrunk 4mm.
I know that she would go into renal exhaustion if she stopped spiriva for >12 hrs because they had her stop all inhalers for 12hrs and she went into total renal exhaustion and hysteria.
