Re cancer and vaccines.
I'm yet to see any convincing evidence of this. The increase in cancer rates could just as easily, and possibly more convincingly, be explained by the fact that we live longer, are better at diagnosing it, plus environmental factors etc etc. There are many things mutating our DNA every day, and there have been as long as humans have existed. It's more amazing to me that we don't ALL get cancer, seeing as it only takes a point mutation in a gene to go awry.
As an aside, there's probably more evidence that viruses cause cancer, eg cervical cancer and HPV. The vaccination in this case is to try to prevent cancers caused by the virus, rather than the other way round. If you want a spectacularly good immune system it would probably be best to avoid sanitation and washing too, but I reckon the bugs would win that fight
.
Again, just my opinion, but I reiterate that I prefer to make choices based on the PROVEN risks of things (like diseases) versus the speculated risk of other things (like vaccines).
But each to there own. You can always find 'evidence' against anything if you're determined to find it, and no amount of arguing can counteract internet scaremongering I often think. The view that 'nature' is best is a difficult one for me, as it is often true, but it is also true that mother nature can be a witch and will try to kill or harm you on a regular basis, indiscriminately. Disease and death is 'natural' and used to be the norm (still is in much of the world
).
