Question from youtube: Hi Lucy, would you still try fenben for cancer today? I know it's off subject but found your other videos and desperately need some advice. Ive got metastatic lung cancer. Please reply.
(Note - I never give advice. And ive never recommended trying fenben, I just set out what happened when I did try it)
Answer: alex, hmm. What I might answer to this question is a very personal decision and everyone must do their own research and make the right decision for them.
Here is how I would break this question down-
1) Is my cancer growing or is it arrested/stopped growing/decreasing at the moment? I would only consider trying if my cancer was growing, and other factors still might stop me doing this. Lots of other things can kill you than cancer if you have cancer.
2) do I have a kras mutation (which i have)? I have heard that kras mutated cancers do especially badly on fenben so NO if I had a kras mutation.
3) have I done all the "basics":
a) to stop taking in bad stuff
have i cleaned up my diet to take out any processed food? am I eating organic? have I ensured im only have super clean water? Have I stopped smoking/vaping?
b) to give my body what it needs to work properly? Have i ensured i have eliminated any vitamin deficiency? Am I supplementing vitamin C, B12, D+k2, omega oils, zinc? Do I have signs of another vitamin or mineral deficiency? Am I moving my body every day doing the maximum ideally getting to 10,000 steps or doing vibration plate etc. Am I doing infrared heat lamp?
c) assessing my poo? Is there more work to be done on my gut biome to make my poos perfectly squidgy, a nice size and shape and formed like a poo emoji? If not id be increasing vegetable variety and fermented foods.
4) what are my conventional options? What is the mood music from the doctors? Do they give me the impression they have this one cracked and I am not at serious risk here? If yes, I would probably allow them to do their thing (in conjunction with 3).
5) Am I feeling better after a period completing 3, or 3 and 4? (Using data from bloods and scans ideally in case I wasnt that great at tuning in to knowing how i was doing)
If cancer still growing/im not feeling amazing after all that, then I would probably consider natural alternatives first like artimisinin.
If 3 and 4 didn't work, id consider off-label drugs, but in all honesty I think fenbendazole gets a lot of airtime in a very peculiar way when other off labels/approaches would seem to be to be more efficient and lower risk with more predictable positive results- examples being subcutaneous mistletoe, or potentially some of the anti malarials. If i did do it, Id also only do a pulse of fenben and then come back to it after a 2-4 week break or so. When we worm our animals with it, they dont have it every day, it is a short course and then you repeat the following month or quarter. Im not sure why humans dosing themselves have adopted a different approach. I would also make sure i had a full metabolic profile alongside it (which would include milk thistle) so that it didnt accelerate the cancer switching to a different pathway and creating further metastases aggressively.
So... is there anything I missed or you think I should have also considered?
Wishing you well x
