Hi I have advance prostrate cancer. O your poor aunt, I know about Fentanyl by the other patient on CC who talk about it, so I know that it an opioid, but really its a synthetic opiate, narcotic, and an analgesia pain killer. Just be carful of it as it been know to depresses the central nervous system, and respiratory function,. so she might find it a bit hard to berthed Last year a scan showed I had the start of bone cancer. It was in my lower back and my ribs. my naturopath Debby put me on very large dose of vitamin C, (or BIO C ) 10mg a day for quite a while, also no sugary foods, no milk, no red meat, Debby told me that for my body to process red meat it has to use an important enzyme that our body uses to dissolves protein to fight cancer. What it dose is dissolves the protein in the protein membrane around cancer cells. About two month ago the vitamin C stop working, I know this as I found my PSA went up three points and I developed urine retention. So ask my doctor can I have an other bone scan, when I had the scan it showed that the cancer in my bone had disappeared. but I still had cancer in my prostrate. .So looks like the vitamin C worked grate for a while. it was taking the weight of the world off of me. over the last few weeks I been on red clover

Can you please tell me what is your aunt primary cancer site I know here body will keep getting use to the Fentanyl so they will just keep increasing the dose I wish you and your aunty well just sorry I cant helop much Take care Ray
