"Cancer is only an imbalance in the temple body mind and emotions"

That's an oversimplified statement. Things most of the time are more complex, multi faceted if you will.
Cancer is the result of a damaged cell that replicates out of control. The immune system normally remove damaged or dangerous cells. But with many people this mechanism seems to be broken and there are some suspicions that vaccines play an instrumental role in this.

And the problem is often people only discover that they have cancer when it had time to spread. Like a friend of me, who had only 3 months to live after he found out and was is very bad shape already. Fasting and deep breathing yoga just aren't gonna cut it then. Maybe if he started 3 years ago it never would have come that far.
