Re: vitamin E

 Other than taking vitamins what natural supplements would be a better way to get vitamin E?

Wheat germ, dandelion leaf, rice bran with the oil are all good sources.

Which theory do think is more likely?virus causes cancer or inflammation causes cancer?

There is not a singular cause of cancer.  Viruses are by far the most common cause of cancers.  I estimate at least 95% of cancers have a viral origin.  But there are also bacterial cancers, fungal cancers, parasitical cancers (extremely rare), radiation induced cancers.  Then  there is the question of carcinogens.  I feel that most carcinogens accelerate the growth of existing cancers as opposed to actually causing the cancers.

What is it about fruits and vegetables that inhibit cancer?

There are a number of things such as polyphenols, chloregenic acid, pectins, quercetin, etc.  Many are antivirals.

What supplements have been shown to be significant cancer inhibitors....preventative and cure?

As far as herbs chagas are still my first choice followed by chaparral, pau d' arco (more for leukemias and lymphomas), andrographis, turmeric,  dulse, myrrh, amla, poke root (very small doses), watercress, ashwagandha, jiaogulan and nettle leaf.  There are many more all serving different functions, but these are some of my favorites.
