IV : CANCER CAUSED BY VIRUSES?
Cancers Linked to Viruses?
the average person that cancer can be caused by a virus and they'll
say something like, "I seriously doubt that." If you are
one of these people, then you should know that according to the Center
for Disease Control, "Infectious agents are
known or suspected to play a role in a number of ... forms of cancer."
Exactly are "Infectious Agents"?
organisms include bacteria, chlamydia, fungi, parasites, prions, rickettsias,
viruses and others.
[ 74 ] Is
there any evidence that viruses in particular cause cancer? Yes, several.
Liver, Breast, Cervical and others. According to Scientific American,
"Over the past 20 years... investigators
have not only proved that many different types of cancer indeed stem
from viruses, bacteria or parasites, they have also learned that perhaps
as many as 15 percent of the world's cancer deaths can be traced to
Liver Cancer: HBsAg Virus Suspected to Play a
rates of liver cancer have been described in the Alaska Native population
[Heyward et al 1981] and the role of infection with
hepatitis B virus in the development of primary liver cancer has also
been observed [Alward et al 1985]. One study in
this population estimated the relative risk of developing primary
liver cancer of HBsAg-positive carriers to be 148 times that of non-carriers
[McMahon et al 1990]." [ 54
studies we can say that cancer is somehow closely connected with certain
viruses, but that does not confirm that these viruses cause liver
Correlation does not prove causation. How do you prove that something
sample of liver cancer cells, filter them to obtain the HBsAg
virus and inject
this into a compatible animal. Will the new animal develop the liver
cancer? Will you find HBsAG-positive carriers EVERY time? If you kill
the HBsAg before injecting it, does the animal then not get the cancer?
If you kill HBsAg in a live animal with the cancer, does the cancer
go away? Science does not have to be difficult. Just answer the above
Cancer: Strong Link to Human Mammary Tumor Virus
ANGELES, Posted 12:45 p.m. August 13, 1999 -- A researcher has found
a strong link between
a virus and breast cancer, a major breakthrough in the search for
a cause to the disease. Scientists are calling the virus the human
mammary tumor virus, reported CBS 2 News. In mice and other animals,
it's long been known that a virus can cause breast cancer, said the
television station. But it was only recently that researchers identified
a similar virus in human breasts. The scientists found the virus present
in 85 percent of all human breast cancers. It's only found in 20 percent
of healthy breasts. "I think this is very intriguing because it is
another virus linked to human cancer," said Dr. Martin Kast, of Loyola
University. "Something is going on." The theory is the virus attaches
to cells and transforms their DNA. Those cells then start dividing
uncontrollably, said CBS 2 News. So if breast cancer is caused by
a virus, it might one day be preventable with a vaccine, the television
station reported. Similar vaccines for other cancers are already being
developed. Researchers at Kast's Loyola laboratory are working on
a vaccine for cervical cancer, a tumor proven to be caused by a virus.
If the same proof is found for breast cancer, a simple shot might
one day prevent that disease. Doctors believe the cancer is passed
down genetically from parents to children. There are other contributing
factors for breast cancer, but the virus could be the most important.
is going on indeed. Okay, we have viruses implicated in liver cancer
] and now we have a "strong link" to breast cancer. [ 63
Cancer: Caused by Human Papilloma Virus:
WHO's International Agency for Research on Cancer (IARC) classified
HPV infection as "carcinogenic" to humans (HPV types 16 and 18), "probably"
carcinogenic (HPV types 31 and 33) and "possibly" carcinogenic (other
HPV types except 6 and 11)" 80 | 81
95% of all Cervical Cancer cases can be attributed to three types
of human papilloma virus (HPV) the virus that causes genital warts.
Here's how it works: In humans and animals, cell division is regulated
largely by two proteins, Rb and p53 [ 82
]. Two genes in HPV, the "E6" and "E7" genes,
produce proteins that can attach to Rb and p53. When the viral gene
proteins attach to Rb and p53, they block their effect on regulating
cell division. Infected cells then reproduce without any control.

The American Cancer Society calls HPV a "risk factor" which
is somewhat curious in light of the fact that HPV-16 and HPV-18 are
classified as "carcinogenic" and the causative model is
crystal clear. Good luck finding the word "virus" on the
American Cancer Society web site.
Sarcoma: Caused by Herpes Virus Type 8
with AIDS often develop a type of cancer called Kaposi's Sarcoma.
Recent research has discovered that a virus, called Human Herpes Virus
type 8 (HHV8) causes these cancers." [ 66
However we still hear that "Most human
cancers are not caused by virues." [ 66
Upon what data is that conclusion based? In
other words, is it simply our inability to detect fragile viruses
with current techniques that causes this assertion? Have our scientists
forgotten how to think?
is Not Caused by a Virus?
Cancer Society says the cause of cancer is currently unknown. They
say that with lung cancer, for example, smoking is a risk factor.
Can we be certain, however, that even with lung cancer there is not
a dormant virus causing tumors when lung tissues are weakened to a
certain point? This would explain why not all smokers get cancer.
Keep in mind that I'm no expert. I'm just a curious bystander with
an interest in science who is trying to understand as much as possible.
now cancers which are proven to be caused by viruses. In this claim
if nothing else, Rife was many years ahead of his time.
