Head and Neck (throat) Cancer

Hi,  I first learned about Chlorine Dioxide in 2020 due to Covid and got some then.  Kind of forgot about it till my husband was diagnosed with HPV+ (P16) cancer about a month ago.  I immediately started him on ivermectin / fenbendazole plus melatonin, curcumin and a host of other powerful antioxidants... and then remembered the CD and got my hands on the books.   Because the anti-oxidents neutralize CD I started alternating the CD days with the antioxidant days because I wanted him to have it all.  He gets the ivermectin and fenbendazole every day, though, without interruption.  His cancer is inoperable and he is already underweight due to other health issues he has survived so he's not wanting to do the chemo/radiation and get put on a feeding tube and potentially lose his ability to swallow.  So we are going it alone.  I cannot find anyone anywhere who has self-treated this cancer.... I mostly hear about breast, colon and prostate cancers.   Hoping to find more answers and direction.   He is getting a PETscan next week to determine the stage but I suspect it had spread before we were aware of it.
Thank you.
