Speculation! Beside trauma is an extreme form of stress this could have been the jump start to bring on the cancer! Besides you don't get cancer in a few days even if it caused by a bacteria or virus! Cancer is a great example of pleomorphism ! The normal cell cannot survive in an acidic anaerobic environment so it morphs from a eukarotic cell to a prokaryotic cell in an attempt to survive an anaerobic environment!
How did she know she was not acidic ,you can eat what you think is healthy ood but if the food itself is mineral deficient it can be more harmful then good causing acidity in itself unless one can knows for sure the environment ,the soil, in which it is grown, you have no way of knowing if it is has vital nutrients, unless one has a refractometer to check its mineral content!
Sorry I still don't beleive there is such a thing as a "Cancer Virus"
