I agree on that you shouldn't only use this treatment. In my opinion, if you do decide to go the natural route and avoid radiation/chemotherapy, there are many changes you need to make. Such as eliminating processed foods, juicing leafy greens, consuming blue-green algae such as spirulina and chlorella, parasite cleansing, supplementation with vitamin b, c, d, e, magnesium, and iodine, etc. No one thing is going to be effective for ridding all cancers. Your best bet is to be as healthy as possible and allow your body all the nutrients it needs to heal itself as it was designed. A protocol such as taking vitamin b-17 is just one of many practices in holistic healing for cancer. At the dosage of 1 or 2 grams per day, it is my opinion that vitamin b-17 will only provide tremendous benefits with little to no risk. Again, everyone should do their own research on what they think is best for them. I'm just posing it as an alternative to treatment. Many people undergo chemo simply because they don't know what else to do or they believe it's the only cure. That's simply not true. Cancer cures are already here but cancer treatment is a multi-billion dollar industry. They aren't going to tell you to try anything natural so you need to think for yourself. Even if you only use the natural protocols in combination with chemotherapy, I suppose that's still a lot better than chemo by itself.
