For decades we thought ulcers were caused by genetics, etc. One doctor realized it was an infection, and he was lambasted for years for this view.

Turns out.... he was correct.

I think there are a variety of conditions that are made better by a regular regimen of D, K, Magnesium, NAC, Zinc, HCQ, Quercetin, and Ivermectin, with twice-a-year deworming with Albendazole/Fenbendazole (I've been doing this for years with Albendazole... need to investigate the difference between these two "-zole" drugs). And I think cancer is one of them. All cancers? How much? I am quite sure I don't know. But I've seen a lot of anecdotal evidence (including here on this thread!) that there is a connection. I am thinking I need to go on prophylactic ivermectin, and should figure out what that would look like (daily? weekly? monthly?)

EDIT: I should add iodine as well. I have started to think that iodine is a key to health.
