Drugs Cause Cancer?

Lipitor has been known to cause very painful and potentially fatal

muscle wasting also known as rhabdomyolysis as detailed and confirmed

by numerous personal comments on two previous articles on this site:

Lipitor - The Human Cost and

Lipitor: Side Effects And Natural Remedy. This side effect is

apparently so widespread that the use of painkillers has skyrocketed

in the wake of increased statin drug use. Recently Crestor, another

similar drug, has also been linked to the drug-induced muscle wasting

disease. Some years ago, a similar drug, Baycol, was withdrawn because

of just this type of side effect.

 

What may be new to many is that cholesterol lowering drugs also cause

an increase in cancer incidence. Shane Ellison, M.Sc. reports that all

cholesterol lowering drugs, both the early drugs known as fibrates

(glofibrate, gemfibrozil) and the newer drugs known as statins

(Lipitor, Pravachol, Zocor), cause cancer in rodents at doses

equivalent to those used by people using the drugs to lower

cholesterol. Human long-term studies on statins are few and those

available were not designed to catch this type of effect.

 

This is all the more important considering some numbers. The reduction

of mortality from heart disease obtained in statin trials is miniscule

- only 1.1% - as opposed to a whooping 1500% increase in breast cancer

among women taking Pravachol. So it would appear that the much touted

benefits of statins may be eclipsed if not completely overpowered by

attendant negative side effects.

 

Here is a copy of Shane's excellent overview:

Cholesterol-Lowering Drugs and Cancer

 

By: Shane Ellison, M.Sc.

The use of cholesterol-lowering drugs for the prevention of heart

disease may increase your chances of suffering from the pandemic

killer known as cancer. Few doctors are aware of this real and present

danger.

 

Well-designed studies have shown the link between cholesterol-lowering

drug use and cancer. In a study published in the Journal of the

American Medical Association (JAMA), Thomas B. Newman MD, MPH and

co-workers show that all cholesterol-lowering drugs, both the early

drugs known as fibrates (glofibrate, gemfibrozil) and the newer drugs

known as statins (Lipitor, Pravachol, Zocor), cause cancer in rodents

at the equivalent doses used by man.[1]

 

The extrapolation of evidence of cancer from rodent to human is very

uncertain. This is the argument of those in favor of using

cholesterol-lowering drugs. The argument would only be plausible if

human studies also showed an increase in cancer rates. And in fact,

that is what science is showing.

 

Evidence from the cholesterol-lowering drug trial known as CARE

(Cholesterol And Recurrent Events) showed that Pravachol (a

cholesterol-lowering drug made by Bristol-Myers Squibb) reduced the

chance of suffering from a heart attack by an absolute reduction rate

of 1.1%. This miniscule benefit was accompanied by a 1500% increase in

breast cancer among women taking Pravachol. An increase in cancer

rates among Pravachol users was also shown in the drug trial known as

PROSPER. (citation)

 

It is rare that cancer would show up in most other

cholesterol-lowering drug trials. Drug company-funded studies for

these drugs are conveniently short in nature, typically 5 years or

less. It can take decades for cancer to develop. Therefore, cancer

rarely shows up. In fact, even heavy smoking will not cause lung

cancer within 5 years.[2] Yet it is a well-known fact that smoking

leads to lung cancer. Therefore, as long as statin drug trials last

only 5 years, this side effect will continue to fly below the radar.

 

If cancer were to show up as a negative side effect, there is concern

whether or not it would be reported. The British Medical Journal (BMJ)

has reported that of 164 statin drug trials reviewed, only 48 reported

the number of participants with one or more negative side effects

caused by the drug.[3]

 

As if in recognition of this, attempts have been made to warn the

public. Dr. Gloria Troendle, deputy director for the Division of

Metabolism and Endocrine Drug Products for the FDA, noted that the

cholesterol-lowering drug gemfibrozil belonged to a class of drugs

that has repeatedly been shown to increase death rates among users.

Moreover, Dr. Troendle stated that she does not believe the FDA has

ever approved a drug for long-term use that was as cancer causing at

human doses as gemfibrozil. Elizabeth Barbehenn, PhD, concluded to the

FDA, " fibrates must be considered as potential human carcinogens and

their carcinogenic potential should be part of the risk benefit

equation for evaluating gemfibrozil. "

 

Historically, FDA advisors were reluctant to approve the

cholesterol-lowering drugs. When asked to vote whether or not the

cholesterol-lowering drug gemfibrozil should be approved for the

prevention of heart disease, only 3 out of 9 members of the FDA

advisory committee voted in favor of approval. Unfortunately, these

votes are only " advisory " and the FDA decided to approve gemfibrozil

for human consumption against the better judgment of the committee.

 

One mechanism by which cholesterol-lowering drugs may cause cancer has

been identified. Published in Nature Medicine, Dr. Michael Simons of

Beth Israel Deaconess Medical Center in Boston shows that statin drugs

mimic a substance known as vascular endothelial growth factor (VEGF).

The biochemical VEGF promotes the growth of new blood vessels, a

process known as angiogenesis. While angiogenesis may help the growth

of arteries, the benefit is quickly negated by the potential for

growth of cancer. The British Journal of Cancer reports that VEGF

plays an important role in the spread of colorectal cancer. Further,

for those who already have tumors, VEGF and compounds that mimic VEGF

significantly diminishes that person's survival time.[4] [5]

 

Benefits associated with cholesterol-lowering drugs do not exceed

risk. Looking at the " statin-drug trials " , not a single

cholesterol-lowering drug prevented all-cause death rates when

compared to a placebo. In laymen terms, this means that none of these

drugs prevented early death from heart disease.(citation)

 

USA Today reported that, " Statins have killed and injured more people

than the government has acknowledged. " [6] Oblivious to their dangers,

medical doctors are calling cholesterol-lowering drugs the " new

aspirin " and are even recommending that children be prescribed

cholesterol-lowering drugs.

 

The medical community failed to protect the public from Vioxx. Now

they are failing to protect them from the dangers of

cholesterol-lowering drugs.

 

Health and longevity was not meant to be risky, complicated or

expensive. To attenuate the risk of using cholesterol-lowering drugs

while preventing heart disease, the general public must utilize

healthy lifestyle habits. Most notably, that would be the act of

quitting sugar and artificial flavors while minimizing grain products

from the diet. This will prove to be simple, effective and most

affordable.
