Could honeybees hold the cure to prostate cancer, and maybe other types of cancer, too? Possibly, according to recent findings from the University of Chicago.
Beehive propolis is used by honeybees to patch up cracks in the hive. It’s made up of amino acids, waxes, resins, and fatty acids and boasts hundreds of complex chemical properties.
Commonly called “bee glue,” propolis is easily purchased in capsule form or as a liquid extract at any good health food store. Companies also sell the extract as an ointment, cream, lotion, powder, or in other cosmetic form. Now comes evidence it stops prostate cancer cells dead in their tracks…

EXPOSED: Mainstream Medicine’s Deadliest Conspiracy
Can you believe this video? It’s a phenomenon. In fact, it was sent to more than 289,000 people in just the first 24 hours!
But you might not see it at all.
Why? Because, for the first time, mainstream medicine’s deadliest conspiracy has been EXPOSED. Finally, this video is the ‘shot heard around the world’ the establishment prayed would never come.
There are powerful interests hell-bent on minimizing the damage it is doing to corporate medicine’s profit machine.
Before it’s banned, watch it here.
According to some sources, propolis has been used for centuries to treat allergies and infections. It’s sometimes even used as a natural antibiotic. In fact, bees use it as their own kind of antibiotic to help protect them from disease. This is partly because it seals out foreign substances that would otherwise pollute the hive.
As a natural remedy, propolis has long been used to heal cuts and protect them against bacteria and other microorganisms. Propolis also appears to have anti-microbial action on both gram-positive and gram-negative micro-organisms.
From a chemical standpoint, propolis is particularly complex. This helps explain why no attempts have been made to create a manufactured version of the substance. But at the same time, because it can’t be patented, very little research has been conducted on the clinical benefits of propolis — till now.
Propolis stops prostate cancer cells in their tracks
The active compound in beehive propolis is called caffeic acid phenethyl ester, or CAPE. Chih-Pin Chuu, a lead researcher on the project at the University of Chicago, wanted to see if CAPE was effective when it came to killing prostate cancer cells.
Chuu tested the amount of CAPE concentration that would be in a person’s blood following ingestion of a propolis capsule.
Results from early culture dish experiments showed CAPE successfully halted growth of early-stage prostate cancer cells. Later experiments on mice implanted with human prostate cancer cells repeated the effect. The tumors in the mice stopped growing if they received CAPE twice a day. But if the treatment stopped, the tumors began to grow again.
Researchers concluded that beehive propolis doesn’t kill prostate cancer, but at least it stops proliferation. The question was, why?
How to starve a cancer cell
The fact that propolis stops cancer cell proliferation hints at the idea that CAPE might someday cross over from holistic treatment to clinical therapy. And from there, CAPE might even prove to be a good co-treatment in conjunction with chemotherapy — according to clinical scientists, that is.
But for that to happen, scientists needed to first prove how CAPE stops cancer cell proliferation.
And that’s where a new breakthrough from the University of Chicago people comes into play. The team was led by Richard Jones, assistant professor in the Ben May Department for Cancer Research and the Institute for Genomics and Systems Biology.
Traditionally, lab tools known as Western blots are used to assess changes in cell proteins after being exposed to different circumstances. But, these tools only allow for a few proteins to be assessed at a time.
The Chicago researchers came up with a new technique, called the micro-western array, for monitoring proteins. It’s groundbreaking, because — unlike previous methods — the technique lets the scientists observe the activity of hundreds of proteins at once. That means there’s finally a way to assess the anti-cancer potential of natural remedies.
Because that’s usually the problem scientists have with natural medicine, isn’t it? They want to assess the effect of just one thing at a time, but most natural remedies are active in multiple ways at the same time. And it’s hard for scientists not to want to break things down to minute detail — which is sometimes important, and often not.
The Chicago researchers have been using their new micro-western array to explain how cell physiology is affected by natural compounds, focusing their efforts on propolis.
They’ve been able to look at the effect of CAPE, the bee propolis extract, on about a hundred different proteins at once, while at the same time assessing a wide spectrum of cellular signaling pathways associated with multiple different outcomes.
They say this gives them a “global landscape view” of all the pathways affected, which wasn’t possible before — that is, to the extent that it would have required hundreds of researchers and an extraordinary amount of money.
At the end of the day, this “landscape view” allowed the scientists to pinpoint exactly what happens at the protein level when chemically-complex CAPE is used to treat prostate cancer. In technical terms, they found that CAPE suppresses protein activity in the p70S6 kinase and Akt pathways.
What’s interesting is that both pathways are nutrition sensors. When activated, they give cancer cells the green light to proliferate. When deactivated, they stop cell growth in its tracks.
Could be the beginning of something big…
As Jones puts it, “CAPE basically stops the ability of prostate cancer cells to sense that there’s nutrition available.” Meaning cancer cells think they’re starving, so they halt growth.
Sounds like a pretty good deal — and all this from a completely natural remedy!
As usual, scientists say a lot more studies are needed, including human trials, before the medical community will recommend CAPE as a legitimate treatment for prostate cancer. And sadly, there’s a concern that nobody will fund the clinical trials needed to prove safety in humans since CAPE/propolis can’t be patented by a money-hungry drug company.
Still, it’s a step in the right direction to know some scientists are starting to welcome natural remedies into their labs for testing and that they’re starting to understand the mechanisms behind alternative therapy.
Does this mean you should add bee propolis supplements to your anti-cancer protocol? I don’t have enough information at this point. Since this newsletter is read by people with a lot of experience at cancer treatment, send me an email (firstname.lastname@example.org) and let me know if you’ve seen it used clinically.
Last issue we identified a particular group of Americans who are likely to see their cancer rate DOUBLE in the next 18 years. If you missed this news, please scroll down and read it now.
Government report predicts cancer risk
for one group will DOUBLE
in the next 20 years!
WHOA! This warning issued by the President’s Cancer Panel in its 2009-2010 report concluded that “cancer incidence among minority populations is projected to nearly double between 2010 and 2030, while increasing 31 percent among the non-Hispanic white population.”
Why are cancer rates soaring among African-Americans and Hispanics? Let’s take a look.
Weight Loss Research Finally Proves it
If You’re Overweight,
It’s Not Your Fault!
Scientists discovered that when you’re overweight your body might be storing more fat than it’s supposed to. Researchers reporting in the prestigious New England Journal of Medicine say it’s all because of a change in metabolism that can happen to anyone.
For the first time ever, leading doctors have discovered a safe, natural solution to the metabolic problem that’s left millions of people around the world overweight and in dangerous health.
To learn more about this breakthrough discovery that has helped some people lose up to 28 lbs in just 10 weeks, watch this presentation now.
The President’s Cancer Panel report cited three primary reasons for soaring cancer rates among minorities:
- They’re disproportionately affected by certain cancers,
- They’re often diagnosed at later stages of disease, and
- They frequently have lower survival rates.
How important is it to address cancer risk by ethnicity? Well, recent population projections show that minorities, who currently make up one-third of the U.S. population, are expected to become the collective majority before the middle of the century!
Let’s take a look at just two examples of how ethnicity impacts cancer risk…
Breast and prostate cancer are tough
on non-white Americans
According to the National Cancer Institute (NCI), white, non-Hispanic women have the highest incidence for breast cancer among all racial groups in the U.S.
But among women aged 40-50, black women actually have a higher incidence of breast cancer than white women. And black women also have the highest death rate from breast cancer.
Why the disparity? For one thing, NCI said the higher death rate may be linked to how advanced the cancer is at the time of diagnosis.
Given that non-Hispanic whites are at greater overall risk of breast cancer but at lower risk of death from that cancer, the problem appears to be one of detection and treatment, rather than actual risk of getting the disease. Studies show that black women often seek treatment when their cancer has advanced to a less treatable stage.
The President’s Cancer Panel says a higher percentage of black Americans and Hispanics lack sufficient health care.
Having a primary care provider increases your chances for receiving the type of routine check-ups and screenings that can detect disorders at an early stage.
So is it all about early detection? More on that in a moment.
Meanwhile, you’ll notice similar findings if you examine the rates for prostate cancer…
Some groups are more likely to die of prostate cancer
According to WebMD, about one man in six will face a prostate cancer diagnosis during his lifetime. But the odds for survival are better than for breast cancer. Only one man in 36 actually dies from the disease.
So which ethnic group is most likely to contain that unfortunate guy?
The answer can be found in the Centers for Disease Control and Prevention (CDC) statistics for annual prostate cancer incidence among 100,000 men during the years 1999-2008.
The results—which are grouped by race and ethnicity—reveal that black men had the highest rate for prostate cancer.
But — somewhat contradicting the theory that being non-white puts you at greater risk — white men had the second highest rate of getting prostate cancer — higher than Hispanic men as well as men from an Asian/Pacific Islander or American Indian/Alaska Native background.
No one fully understands the reasons for these racial differences. But some experts say they could be linked to environmental factors such as high-fat diets, exposure to heavy metals such as cadmium, infectious agents, or smoking.
One thing for certain is that predictions surrounding future mortality rates for all ethnic groups are troubling…
Dr. LaSalle D. Lefall, Jr., a professor of surgery at Howard University and Margaret Kripke, PhD, a professor at University of Texas’ M.D. Anderson Cancer Center are the principal members of the President’s Cancer Panel.
In the panel’s report, America’s Demographic and Cultural Transformation: Implications for Cancer, Lefall and Kripke express concern about how hard it is to determine the impact the increases in non-white cancer rates will have on overall cancer incidence and mortality. They said this is mainly due to limits imposed by current data collection efforts.
The numbers don’t lie… or DO THEY?
Current statistics on cancer incidence are based mainly on social definitions of race and ethnicity. The report says it’s well known that these numbers are imprecise because they focus primarily on non-Hispanic white populations.
Lefall and Kripke contend that risk factors, screening guidelines, and treatment regimens identified for one population are not necessarily appropriate for an increasingly diverse population of Americans who are not of European descent.
This also means that the medical and scientific communities have a limited understanding of exactly how key factors influence a person’s risk of getting cancer.
And because of this limited understanding—the nation is sorely lacking in medical assistance to help reduce the number of Americans with cancer.
A call to action
Researchers will continue to dig for answers about why minority groups are disproportionately impacted by some cancers.
In the meantime, the President’s Cancer Panel recommends specific things that should be done to improve cancer care for a changing national demographic.
For example, the panel recommends:
- Teaching students about culture differences in medical school and other healthcare training curricula
- Conducting more research on genetic ancestry and how specific genes influence cancer risk
- Evaluating cancer screening guidelines to determine if they’re accurate when it comes to assessing disease risk in members of different ethnic groups
The President’s Cancer Panel recognizes the need for “effective cancer education and services across the cancer continuum that reach beyond traditional ideas of race, ethnicity, and culture.”
We can only hope that the government and medical establishment will press for pursuit of such goals that could help reduce the burden of cancer for all Americans.
But. . .don’t wait for Big Medicine to solve your problems
No doubt non-Hispanic whites — and higher income people in general — get more mammograms, more PSA tests, more prostate and breast biopsies and more “touch” exams of the breast and prostate.
Readers of this newsletter know that all this screening is a mixed blessing. Mammograms are inaccurate and the annual mega-dose of radiation actually increases a woman’s risk of cancer. PSA exams are next to worthless. Both tests lead to multiple unnecessary and damaging biopsies and — especially in the case of prostate — unneeded surgeries for unthreatening tumors that might be best left alone.
My guess is that other ethnic and income groups might benefit from more screening while the white and affluent would almost surely benefit from less. It’s a difficult question.
I don’t believe in one-size-fits-all social answers to questions that are essentially personal and individual. The best you can do is be as informed as you can about your options and take an active role in your own health rather than wait for someone in Washington to order up a test or procedure for you.
Easy to say, I know, for someone like myself who’s educated and a compulsive reader. But I simply don’t have a better answer. In a couple of hours on our website, a person who can read at a 9th grade level can garner as much information as he or she needs to make a better cancer decision than the “experts” are likely to make for you. So that’s what I recommend.
