Great example of oncogenic viruses. I have tried to explain to people the role of viruses in causing cancer for so long. But seems like I hit walls with people on this topic more often than not. For example on the breast cancer forum recently the moderator was disagreeing that viruses cause cancer and that cancer was a result of inflammation. He is also a big oleander supporter. So when I pointed out on the board that this contradicts his own claims that oleander works for cancer he hid my post and threatened to ban me from the forum. He totally ignored the fact that all oleander does that we know of is to provide immune stimulating polysaccharides, which can be derived from all sorts of non-poisonous sources such as seaweeds, mushrooms, myrrh, etc. that do not have to be processed to make them non-poisonous like oleander has to be. These polysaccharides do not reduce inflammation though. All they can really do is to help activate the immune system to help fight cancer microbes. Therefore if cancer resulted from inflammation instead of cancer microbes, which he does not believe exist, then by his own reasoning oleander would have no effect on fighting cancer. This is a great example of people going to great lengths to deny the fact that cancer microbes are real and do cause cancer.
In fact cancer viruses have been known since 1908. And many of these microbes have been positively linked to cancer. For example:
HPV viruses have been linked to cervical, breast, prostate, skin and nasopharyngeal cancers.
Human T cell leukemia/lymphoma viruses, 1 through 4, including the HIV virus (HTLV III) are associated with various leukemias and lymphomas.
Epstein Barre' virus has been linked to lymphoma.
Human herpes virus type 8 has been linked to Kaposi's sarcoma. There is also a bacteria induced Kaposi's sarcoma.
The fungus Aspergillus niger produces aflatoxins linked to liver cancer.
Hepatitis viruses have also been linked to liver cancer.
These are just some of the examples of microbial induced cancers. Even the so-called hereditary cancers have been proven to be of viral origin. An article a while back in Dicover magazine had pointed out that every oncogene that had ever been identified was viral, and that NO human oncogene had ever been discovered.
If they want to really cure cancer they are going to have to learn the role of cancer viruses so they can be addressed. One of the main reasons cancer tends to come back after a few years is that the cancer causing microbes are not being addressed. If they can cause cancer the first time this means they can cause cancer again, especially when the immune system is further suppressed with chemotherapy and/or radiation therapy.
