Cancer Prevention and Treatment May Be the Same Thing

The breast cancer you may feel one day as a lump in the shower may have started 20 years before. We now suspect that all the epithelial cancers — breast, colon, lung, pancreas, prostate, ovarian, the ones that cause the vast majority of cancer deaths — may have been growing for up to 20 years or more. By the time it’s picked up, it may have already been growing, maturing, scheming for years, acquiring hundreds of new survival-of-the-fittest mutations to grow even quicker, better undermine our immune system.

So called early detection, like mammogram, is really, really late detection. People are considered “healthy” until they show symptoms but if we’ve been harboring a malignancy for 20 years we may feel all right, but we haven’t been.

So many people who do the right thing and improve their diet in hopes of preventing cancer may very well at that very moment be treating it, as well.

Cancer prevention and treatment may sometimes be the same thing.

Breast cancer can take decades to develop, so early detection via mammogram may be too late. Have a question about this video? Leave it in the comment section at… and I’ll try to answer it!
