Adenoid cystic carcinoma stage 4 locally advanced - Perineural invasion

Hi, i was diagnosed at the end of last year. I was told it was inoperable, chemo and immunotherapy wasn't an option only 7 weeks of radiotherapy.

After radiation I spent 1 month in hospice. The drs didn't know how long I had left, whether I would be alive in another 1mth,6mths,12 or max 24mths.

My options were limited, death a certainty.  I started taking fenbendazole mixed with dmso + distilled water. Annatto, cimetidine, berberine, green tea extract, vitamin d3 2000iu, curcumin. 

3hrs later 12mg ivermectin mixed with same dmso shot, mushroom extract and curcumin. 

Before bed 800mg albendazole mixed with same dmso shot, berberine, magnesium, vitamin d with k 6000iu, Annatto, cimetidine, tudca for liver support. I take this for 4 days then take a break of 3 days.

My follow up scan shows my tumor has shrunk 80percent in 5mths.

Chemo and immunotherapy was mentioned at last scan,ive continued my protocol and next scan is in another 4 weeks.

The dr described that the full length of the tumor has thinned out.

I have no pain at all now, just a slight lump which is numb, its where the tumor was. At my next scan i really believe I will see NED. I'm wondering when a tumor like adenoid cystic carcinoma shrinks 80percent in 5mths, what is the remaining 20 mostly made of? Dead cells and scar tissue. Thanks

Paul.
