Ever since connie posted her concerns about HA and cancer, I have been looking out for more information.
On the cancer front, it was not clear to me when I read the studies, if the additional HA near the cancer was feeding it, or was a response to it.
However, and there also seems to be some contradiciton to this, but HA may feed viruses: http://www.ncbi.nlm.nih.gov/m/pubmed/22859551/
I have found some contradictory information on this, but I've read enough to be concerned.
We also know that viruses can develop into some cancers.
This is tricky, particularly when we have dogs with severe joint problems, or heart murmurs.
And I'm not sure what the *exact* relationship is. But since I have been an advocate of it here, I wanted to post an update on what I've found.
