Can an aspirin a day keep cancer away?

Can an aspirin a day keep cancer away?

Aspirin is recognized for its effects in heart-attack prevention. And several studies “have provided evidence that nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin, may hold promise in helping to prevent cancer,” according to the National Cancer Institute. 

There’s a long history of research on aspirin and cancer, starting in the early 1990s. But can an aspirin a day keep cancer away?

It’s not quite that simple, although two studies published in the Lancet and one in Lancet Oncology suggest that aspirin could have some protective effects against cancer.

From a tree, a 'miracle' called aspirin

All three studies were conducted by Dr. Peter M. Rothwell and his colleagues at the University of Oxford and John Radcliffe Hospital, Oxford, United Kingdom.

In the first study published in the Lancet, the researchers found that the aspirin users had reduced cancer deaths (562 to 664 deaths) and fewer nonvascular deaths (1,021 to 1,173 deaths) – these are causes unrelated to the heart or circulatory system. These findings were based on 34 studies.

In 51 trials, aspirin users had lower nonvascular deaths and had reduced in-trial cancer deaths by nearly 40% after about five years.

The findings only applied to daily users of aspirin, not studies in which subjects consumed aspirin every other day.

In six prevention trials, aspirin users had reduced cancer incidence from three years onward by 324 cases compared with 421 cases in the groups who did not consume aspirin.

Rothwell and his colleagues wrote that the results in the short-term reductions in cancer incidence and mortality “add to the case for daily aspirin in prevention of cancer.”

Eric Jacobs, director of pharmacoepidemiology for the American Cancer Society, said it would take time for the scientific community to evaluate these new findings with existing evidence.

Using aspirin to help cancer prevention is not necessarily a new concept; previous studies have shown evidence it is particularly helpful in colorectal cancers.

“It is not entirely clear how aspirin works to prevent colorectal cancer and possibly other cancers,” Jacobs said.  “These recent studies are finding apparent effects at very low doses that suggest the effects of aspirin on platelets may be important for cancer.  Platelets are affected by very low doses of aspirin.”

Although daily aspirin has some promising benefits, it can also raise the risk of gastrointestinal bleeding.

Even low doses of aspirin can increase risk of stomach bleeding,” Jacobs said.  “Low doses can help prevent heart attacks because they stop the platelets from sticking together and causing clots.  They can, even in low doses, increase the risk of bleeding.”

Before popping aspirin for the sake of cancer prevention, Jacobs warned that a person should consult his or her doctors.

“It’s a balance of the overall risk and overall benefits,” he said.

 The second article published in the Lancet indicated that aspirin could affect how cancer grows and spreads.  The authors collected data from five studies totaling 17,285 patients in the United Kingdom.

The people in the experiment group took daily aspirin (less than 75 mg). The study found the aspirin reduced risk in cancers in the colon, lung and prostate by 46%, and other cancers, such as those in the bladder and kidney, by 18%.

“Allocation to aspirin reduced the incidence of new cancers during the trials,” wrote the researchers.

The third study published in Lancet Oncology observed the same effect from aspirin when the authors examined observational studies instead of trials.  The results of the observational studies were 38% reduced risk of colorectal cancer among aspirin users.

In an accompanying commentary entitled, “Are we ready to recommend aspirin for cancer prevention?” two doctors commenting on the study wrote: “This finding was the first convincing evidence that aspirin might prevent death from several cancers, thereby widening its potential population-wide effect.”

But they wrote that the Rothwell studies didn’t include the trials in which subjects took aspirin every other day.

“Despite a convincing case that the vascular and anticancer benefits of aspirin outweigh the harms of major extracranial bleeding, these analyses do not account for less serious adverse effects on quality of life, such as less severe bleeding.”

    Yes, but did they have reduced "cancer" deaths because they had increased deaths from another cause? Wishing these articles on studies would use a little logic in their arguments...

      Cancer is probably the worst disease to suffer through. You insult everyone who has had to watch someone they love suffer from this horrible disease, by somehow making it sound like saving people from cancer- even if they develop another condition, like stomach bleeding which is much more controllable- is not really saving them.

      Maybe you never lost someone to cancer... but I have, and I am in the process of it again... and it stinks... and I know there really is not much worse then that.

      Joe makes a good point. Taking any kind of blood thinner regularly (such as aspirin) increases calcification in the blood vessels and greatly increases risks of heart attacks at an early age. Seriously, don't take an aspirin a day unless your doctor says to do so.

      The active ingredient in marijuana cuts tumor growth in common lung cancer in half and significantly reduces the ability of the cancer to spread, say researchers at Harvard University who tested the chemical in both lab and mouse studies.

      source: http://www.sciencedaily.com/releases/2007/04/070417193338.htm

      The new findings “were against our expectations,” said Donald Tashkin of the University of California at Los Angeles, a pulmonologist who has studied marijuana for 30 years.

      “We hypothesized that there would be a positive association between marijuana use and lung cancer, and that the association would be more positive with heavier use,” he said. “What we found instead was no association at all, and even a suggestion of some protective effect.”

      I agree neither are good. I have a problem with GI bleeding which limits my pain management choices, but I think if I had been smart and used a doctor to manage my pain early on I would not have developed an ulcer from NSAIDS. These drugs are a double edged sword, but some people can take them with no problems at all. I do wish I could. They are a miracle in a pill for inflammatory conditions.

      Another one. Yes death is death, so I guess you would give your heart away to someone dieing right now... even though it would mean you would die... I mean death is death to you, so what do you care about life?

      Yeah I guess you most likely won't. Cancer is a horrible disease... and no one want to go through that. It is painful. It hurts families, families who have to helplessly watch their loved ones slip away. It hurts the person who slowly fades away... getting worse by the day. Maybe you think that death is death... but you are wrong. Some deaths are much worse then others.

    Frustrating to see the news du jour present data that really is not conclusive in a manner that would give the average person reason to believe popping an aspirin a day might hope to cure cancer. This article did nothing to paint the background of the subjects studied and or report on their other health related items (age, sex, weight, diet, other diseases, etc). Without such data, this is a reckless presentation to the masses.

    Maybe it's because people who take aspirin every day are interested in their health, and are more likely to have other preventative care and behaviors, like eating healthy, exercising and having yearly physicals? I can't tell if the study gave people aspirin who weren't taking it or if they just used anecdotal evidence, like chart reviews, to perform their study.

      That would indeed be a confound in the observational studies that are cites, but not in the controlled trials, where people are randomly assigned to a placebo or the treatment. These were not case studies either, and that is clear from the article. (It wouldn't be worth talking about if any of these concerns applied!)

      I am a Patient Advocate for a large hospital in LA. I wish I could reproduce letters I get from patients and their families about Graviola and their recovery from breast cancer. The doctors at our hospital put their patients on Graviola before they do any chemo. Then they will wait and do blood work again before any chemo is considered. What they say about Graviola is true. It does kill cancer cells and is not toxic. The drug companies are hiding this plant because they can not make money from it.

      The LA Medical also gives patients the option of going home and taking the tea for 30 days and repeating their blood work. Results are amazing.

      There have been no clinical trials with the scam called Graviola. As such, it is reckless to use in a medical setting. If you're treating patients with this, you're on dangerous ground. You're also open to a lawsuit if you make a claim regarding treatment and it doesn't work.

      Preliminary because the 34 studies were published in a meta-analysis which just demonstrated a cross sectional association, not causailty. There has been no conclusive evidence of what underlying mechanism may actually be reducing the cancer. Cross sectional data are not nearly as convincing as randomized controlled trials.

    The issue is that these are not full randomized placebo controlled studies. This would be hard to do if not impossible requiring huge sample size and very long time (event driven). The studies cited are subject to enormous confounding or treatment by indication bias. These are complex issues and data that the general public cannot understand and grasp. It is sad that Sanjay Gupta feels that it is appropriTe to communicate this information. This is best left for the academic community to debate because as is, guidance to physcians is really impossible at this point. All Nsaids do carry risk, not only GI but also cardiovascular, and this is not emphasized in the article. Nsaids are indicated for pain relief and aspirin is used for cv prevention after a risknhas been identified. The evidence is strong here. But cancer? This article sends the wrong message and violates primum non nocere. Cnn should way the benefits and risks of communicating scientific information before it is thoroughly evaluated by the medical community.

    COX-2, an enzyme in the body that is associated with inflammation, has been linked to the development of a number of cancers. Aspirin blocks the effects of COX-2, and the use of aspirin has, in many clinical studies, been associated with a reduction in cancer risk (and most notably with regards to colon and rectal cancer). The downside of regular aspirin use (whether for cancer reduction purposes or to reduce the risk of cardiovascular disease) is its well known side effects, including GI tract ulcers, bleeding, and kidney disease. However, there is strong data supporting the use of low-dose aspirin as a cancer prevention agent in patients who are at particularly high risk for colorectal cancer due to inherited cancer syndromes. The findings of these 3 studies support the findings of previous cancer prevention studies while also suggesting a potential role for low-dose cancer as a so-called adjuvant therapy in the management of colorectal cancer as well.

His lung cancer is also in remission. People should take these plants seriously. Read about the research and write their congressman about the cover-up with the drug companies.

      Was that your father on National Geographic? I saw the program. A guy was laying in a bed of leaves and water. The leaves were Guanabana. They put the leaves into the water for 24 hours to soak. Then the guy was put in the water for 2 hours. They did this for 8 days. He was also allowed to drink the Guanabana...not the bath water!

      Nat Geo did a re-sampling of the blood work after the 15th day. But the obvious was that the lesions on his skin were healing. I don't remember the numbers on the blood work, but it was significant. The still photos of his skin showed a dramatic change. At the end of the program they showed a photo of him 4 months later. It was amazing! But also during that 4 months he drank 4 glasses of the tea every day.

      Very, very bad advice. NO ONE should start self-medicating with aspirin or any other drug without consulting a doctor first. All drugs have side effects, including low doses of aspirin, that can interact with existing conditions and make them worse. Aspirin is certainly useful to reduce clot damage following heart attacks, but not for everyone, and the same will certainly turn out to be true for using it to ameliorate cancer, should that pan out.

    It's seldom contemplated, but nevertheless true that everything in the universe is made from the same stuff and only technology advanced enough prevents us from accessing the keys which will provide us with the ability to overcome our present limitations, including the aging process. We are our own resource for eternal living and such a reality doesn't come by waiting for death to consume us, but alternatively the wait for science to make it a reality.

    The riches of the universe are ours for the taking, but they're in the form of persistence of human life through discovery. We will one day have technology capable of surpassing all barriers that presently limit our health and longevity, limitations that will one day simply be represented by words in a history lesson somewhere.

    Most fascinating of all is that our evolution is steadily coming under our own influence rather than purely relegated to Mother Nature's own influence and we are the only species thus far which has the capacity of awareness to the universe and our place in it. That unique factor yields the power to stretch beyond mere existence and to utilize vast resources in ways that will one day represent the the entirety of forces which dictate human evolution.

      Pharma companies spend years on research, trials, and FDA approvals – and even then, only 1 out of 10 drugs make it to market. They take the hit on the 9 that don't make it and recoup their costs on the one that does.

      Even then, if such a miracle cure was developed, there is money in patenting the manufacturing process and the delivery method, but don't let a lack of understanding get in the way of your rant.

      Lastly, if you think that the pharma companies are gouging you, start your own. Pony up the dough to build a factory and maintain it to ISO 13485 and CFR 820 regulations. Train a fleet of quality system people and hire chemical engineers and biochemists to do research. And then whine when people want the output of your millions of dollars in investment for 10 cents a pill.

      I just had my kidney tumor removed on Feb 10th. It was also malignant. Thank God it was contained. No Chemo or Radiation. It was 9 cm big. I was told to stay away from Aspirin from my Dr. very hard on the kidneys. Good luck to your husband I will pray for him

      Do your own research on Chanca Piedra and Graviola. Google it. Go read the NIH reports, NCI reports and drug company reports. The FDA even has a report. Take a look at the names of the individuals that are researching it. Read the information from Purdue University and other universities. Keep in mind that the drug companies would like to patent the whole plant so to speak. Eli Lilly has $90 million dollars researching Chanca Piedra and Graviola.

      This is not "snake oil". This is fact.

      There isn't anyone that is getting rich selling this plant leaf. It is safe and it is effective.

      "There isn't anyone that is getting rich selling this plant leaf. It is safe and it is effective"

      Show me a single peer-reviewed study which generated results replicated by another study, complete with effectivity (since, after all, many pushers of the scam claim that it is 10,000 times mroe effective than other cancer-fighting drugs) and known side effects on a statistically-relevant sample size.

      Go ahead. We'll wait.

      I drink Chanca Piedra and Guanabana with a twist of lemon on ice.

      I was diagnosed with polycystic kidneys in 2005. I had 6 cysts on my right kidney and 2 on my left. Both kidneys caused pain. The problem was increasing blood pressure and causing liver problems also.

      I went to Kettering in Denver and they put me on Chanca Piedra. After 4 days the pain went away! The kidneys began to shrink to normal size. After 30 days they added Guanabana or otherwise known as Graviola.

      In April I will have been drinking this tea for 7 years. Surgery has been eliminated. I feel fine! I do not take Atenolol for blood pressure anymore. I do not take Prazosin for enlarged prostrate anymore.

      I know other patients that went to Kettering and they will testify to the same experience.

      Chanca Piedra works. Graviola works.

      These rain forest plants are not a scam. They are not new. They are not someone's idea of a get rich quick scam. These plants and their usage has been around for a few thousand years.

      Didn't aspirin come from bark? Many chemicals in drugs come from plants. Read up on the drug companies that have researched these plants and other plants.

      Be aware that there are false claims about both plants. Some companies claim miracles.

Remember a little thing called thalidomide? Wonder drug, the pushers said. Safe and effective, the pushers said. The FDA did its review and forbade its approval.

      Then there's a few studies and OOPS! Sorry, we missed the bit about birth defects.

    Dr. Isiah Fidler at the M.D. Anderson Cancer Center has been touting aspiring as a prevention for metastasis for decades, since the 60s. Cancer cells, to metastasize, but pass through a number of obstacles, including passage via the bloodstream. Cancer cells, by themselves, cannot survive the high speed of the bloodstream, but in clumps with platelets and other cells, can. Aspirin prevents the clumping, and thus can act against metastasis, and as all cancer docs know, it is usually the metastasis that kills the patient, not the primary tumor.

    Interesting. Inflammation is thought to be a factor in many diseases so reducing it would seem to help. However people on blood thinners also have more microbleeds in the capillaries of their brain, and this is correlated with dementia and neurodegeneration. Of course a lot more research is needed in this area.

    Study brought to you by Bayer aspirin. I question everything I hear in these stupid reports. Bottom line is there are side affects to every drug. The human body is a chemical machine and anything you introduce into your body has consequences. Before I take any drug the benefits better far out way the side effects.

    Aspirin and a few shots of Canadian whisky saved me from a "widow maker" heart attack. Nothing that the PHDs gave me did anything to prevent it. I take aspirin every day now. Don't know if it will prevent cancer or not, but it was one of the first and probably the best drug ever discovered.

    If this is a miracle and asprin can indeed stop some cancers the American Medical Association will fight you on that one. How could something so simple and inexpensive prevent companies from making billions on THEIR expensive drugs?

Drug companies help medical students financially hoping for their loyalty when they get in practice. Drug company reps and radiation equip. reps sit on some hospital boads...guess what they will recommend for the treatment of cancer....drugs and radiation. People in this country need to wake up. God put these plants on this earth for a reason, they will heal us...not rich pharmaceutical companies.

    Aspirin is a closely related derivative of salicylic acid, a plant hormone that plays an essential role in plant development and resistance to plant pathogens (i.e. bacteria, fungi, viruses). It shouldn't come as a surprise therefore that there are demonstrated health benefits to its use. The human species is pretty far removed from plant life (although I can think of many individuals who blur that distinction), but there are many shared commonalities with respect to fundamental metabolic pathways and their physiological relevance. As for those of you taking Excedrin on a routine basis, it's not aspirin and I'd seriously consider having a liver test during your next physical.

      Uh – there is enormous interest and research on cancers caused by infectious agents; vaccines against various strains of HPV, for example, dramatically lower cervical cancer rates. However, it is unlikely that all cancers are a result of infectious agents – many are quite clearly a result of exposure to carcinogenic agents. And in any case, there's no harm in searching for more immediate treatments while primary causes remain unknown or untreatable.

    Why does CNN advertise Bayer's product Aspirin? Aspirin is a trademark, not a medical substans. Any drug containing only acetyl salicylic acid would help against cancer. (Is there only ONE product containing only acetyl salicylic acid on the U.S. market?) "acetyl salicylic acid" isn't even mentioned... This is comparable to an article about inline-skating, talking about Rollerblades and never using the term "inline-skating".

    reading comments here, it appears there is an ongoing discussion of eastern medical philosophy versus western. I'd say both Eastern and Western have extreme merits, yet each dismisses the other as useless or conspiracy. BOTH have valuable contributions to our health, it helps no one to dismiss the miracles of either.

    Before any of these treatments actually 'prevent' anything, you would have to be at risk of becoming ill in the first place. The problem with Eastern medicine is that there is no data to analyze. The problem with western medicine is that if there is no profit in a treatment, it will go unstudied.

    The medical professionals never told me to take aspirin before my heart attach. They gave me all kinds of pills for cholesterol and blood pressure. I was told their program (of poison) would help prevent it. Well it did not ! ! ! I started taking aspirin when I had my heart attack..(12 years ago)..I no longer swallow all that poison they prescribed....Guess what happened...My blood pressure came down, my cholesterol HDL/LDL improved, and the acid reflux went away. Aspirin is the ONLY DRUG THAT HELPED.....Oh yea. I no longer have muscle aches or headaches. ...And..no history of cancer.
