I'm very humbled at how loving and concerned you are for this person. I do think she needs to look at her lab reports so that she knows exactly what she has. I think she would also benefit from HPV DNA testing. Roche has one called AMPLICOR that will tell her exactly which strain(s) she has. That way, if she does prefer to address it through alternative means, she'll know exactly how to set up a strategy. The only test the FDA approves is Digene, but that will only tell her she's been exposed to HPV. It won't tell her what she has. But the FDA has a cozy relationship with certain corporations, so she may have to pay for Roche's HPV DNA test herself. She may also have to go to a teaching hospital to get access to it if her doctor doesn't have it.
Is she working with a holistic doctor or a naturopathic doctor or an accupuncturist or any other professional who practices eastern medicine? Something I was told is that it's best to work with a professional who can tailor the alternative treatment for her body's special needs. In addition, why is she taking laxatives? Unless she's working with a professional, it seems the laxatives may be creating more stress on her body if she doesn't really need them. You might also want to check the alternative medicine forum, on this site, and see what they have to suggest for her.
Yes, I believe stress impacts our health. It puts too much of a load on the body's immune system. When that immune system breaks down, bacteria, viruses, etc., have an easier time prolonging their exposure and making it easier to cause disease.
