Be very careful. The Government and FDA are not to be trusted. They've spread lies about the seeds and actually banned them as being cancer treatment. Why? Money. They make loads of money when people by a life time supply of their pills that only treat cancer, not cure it. They lose all of this money if people cured their cancer by eating these seeds.
Now, how the seeds can do it? Apricot seeds has a lot of Vitamin B-17 which attacks Cancer Cells and kills them. Eating enough seeds per day will eventually lead to all of your Cancer Cells getting killed thus curing yourself. You will go into a comma afterwards due to lack of cells but you wont die. Your body will heal itself during this time and once you wake up, you will be healthy once again.
Actually, this guy cured his cancer. He did research on the seeds then begin eating a lot of them. After awhile, he was in a comma for 2 days and when he awoke, he went to the doctor and figured out his cancer was gone. He actually begun selling the seeds as a "cure" and had over 40,000 happy customers. But sadly, the FDA arrested him for some stupid crap they made up because they don't want to lose money. I think he was sent to jail for 20 years. (Off-topic, ik but this will be my last since I have no more to say)
~Edit~
Oh and yes. Apricot seeds does contain that stuff you've said but it is in a form that shows min risk of harming your cells. In other words, it rarely kills people.
Erh ...
1) I live in Europe, so the American government and FDA don't really apply to me. Besides that, I always look up more information on the internet for my studies (you're right about apricot seeds being non-lethal of course, I just wanted to say they're not entirely healthy), and I don't mean Wikipedia. More like actual published stuff in different science magazines. And yes unfortunately, even these things can't always be trusted. They're all human ideas after all, and humans aren't, and never will be, perfect.
2) attacking cancer cells won't really help you if it's already too widespread in your body. Don't forget they're your own body cells, with a very abnormal reproduction rate. Cancer cells are no viruses or bacteria. It's not an easy feat to "cure" cancer, as it's your own body you have to stop going all crazy on you. You can't simply destroy them and expect your body to regenerate the loss: way too dangerous. Not all cells can be regenerated either; in fact, most can't.
3) "this guy". What guy? What's his name? Again, sources please. Aside from that, "this guy" definitely doesn't know what scientific research means if I may believe you, as he (a.) only tried it out on himself. Because something works on one guy, doesn't mean it automatically will work on the next, and indeed even the whole human populace. (b.) didn't reproduce the experiment to check if it wasn't a fluke (or maybe even if some doctor (accidentally) injected him with a medicine in the hospital where he slept during his coma, and which just so happens to work against cancer). Reproducibility and reliableness, two very important words when doing research.
4) I'm open to a lot, but keep in mind people with cancer are desperate, and will try anything -even the most ridicule stuff- to get cured from it (no I'm not referencing to your seeds. I'm neutral about that anyway, since I have never seen someone put such seeds and cancer together in scientific research). In other words: they can be pretty naive, and get manipulated pretty easily. Make sure you don't abuse that, even if by accident.
Anyway, point 4 was actually what I was kinda trying to bring over. Be careful with what you say. You can't claim something is a fact when you can't prove it. Or vice versa. Wrong information is the worst kindyou can provide, as it's also the kind which isn't so easy to erase again.
*ahem* Over to Skyrim again.
