Re: Please, help!
No I never underwent chemo or any other mainstream treatment. The flax seed oil/cottage cheese blend is part of the Budwig protocol that you should google. It has other components like a specific diet, sunshine exposure, sauerkraut (for probiotics) etc. Trust me, it wasn't recommended by a doctor but discovering it on cancertutor.com and doing further research of my own.
The Budwig mix eliminates rectal pain immediately (for me) and has shrunken the tumor to have normal bowel movements again. For those reasons plus all the research that has proven the value of flax seed oil to colon health has me convinced it's especially useful for colorectal cancer. It has been for me at least.
I haven't been in for another checkup in years. When you're not using mainstream treatment, you tend to stay away. Never know if your health insurance gets cancelled, or you get coerced into it by the state, health insurance, well meaning family, etc.
If I start feeling badly again or the tumor gets worse I probably WOULD look at ozone therapy as a next step. But given my results with Budwig I'll never give it up and should be the first thing your friend looks into IMO.
