As many as 37% of breast cancer cases may be caused by exposure to bovine leukemia virus.
Breast cancer outbreak continues increase All over the world. In the United States, it Amount Incidence increased by 40% by the end of the century. Currently, the main way to prevent mortality Is Early detection and treatment. This is important, but why isn’t more attention paid to primary prevention – protecting people from risk factors so they don’t develop breast cancer?
“Overall, it is estimated 20% of all human cancers have infectious origins.” Viruses can trigger Turning on cancer genes or turning off cancer-suppressing genes causes cancer, but they can also contribute to tumor formation by causing chronic inflammation. Currently there are cancer causing viruses Agreed “The major plausible hypothesis for the direct cause of human breast cancer.” How did we get here?
It all started nearly 40 years ago when a professor of virology at UC Berkeley learned How mammary tumor virus was discovered in mice. Scientists replaced mouse pups from mothers with a high incidence of breast cancer with strains of mice with a low incidence and found that the incidence of cancer in the pups matched that of their foster mothers – not their biological mothers – indicating that it was not genetic. “It occurred to me that humans are raised on cows,” the professor said.
Bovine leukemia virus (BLV) was just Identified As a cancer-causing cow virus. At the time, only 10% of US dairy cows were infected, but now it is closer to half. Initially, 66% of the herd was affected. Then, this Was About 80%, based on testing positive for the virus in their milk, and 100% of herds in large industrial farms. And now, more than 94% of Americans are flocking AffectedContinuing the historical trend of BLV becoming increasingly widespread in US dairy herds.
We have known for a long time that people in those countries consume Milk causes the highest number of breast cancer cases. But, as you can see below and at 2:32 in my video, Bovine leukemia virus as a cause of breast cancerAssociation between dairy consumption and breast cancer incidence Not there. Only at country level.individual women who are lactose intolerant and consume Eating less dairy also appears to reduce the risk of breast cancer. Milk contains several things that may contribute to cancer risk, such as saturated fat and the presence of cancer-promoting growth hormones like IGF-1.
Yes, we know the Bovine Leukemia Virus Is Present in beef and dairy products. About half of milk and meat samples turn Positive for virus. Actually, you can Sample The virus spreads directly through the air on dairy farms, on surfaces and in the milk itself. Most milk is pasteurized, but many dairy products, such as raw, aged cheese, are not pasteurized. And who hasn’t? ate A pink hamburger at some point in their life?
yes, we have evidence that people are exposed To the virus. Yes, we have evidence that people are active infected With virus. But it was not until 2015 that we learned Infection rates were highest in cancerous breast tissue, as you can see below and at 3:30 in my Video.
So much so that about 37% of cases are breast cancer. May Bovine leukemia can be caused by exposure to viruses.
This was enough for me to create a whole series of videos on the virus’s role in breast cancer and how the meat and dairy industries reacted to this news. What is the latest update? This is what I will cover next.
doctor’s note
You may remember that I have discussed before Role of Bovine Leukemia in Breast Cancer and this Industry response to Bovine Leukemia Virus in breast cancer.
Stay tuned for the next video: Breast Cancer and Bovine Leukemia Virus in Meat and Dairy.
