A drink a day increases breast cancer risk

Even moderate drinking increases a woman’s breast cancer risk, according to a study published Tuesday in the Journal of the American Medical Association.

The research found as few as three to six glasses of wine a week increased the chance of developing breast cancer. The risk of breast cancer rose with the amount of alcohol consumed, the study found, with the best measure of risk being a woman’s cumulative alcohol consumption throughout her lifetime.

“This study doesn’t tell women, ‘Don’t drink at all,’” said Dr. Wendy Chen, lead author and assistant professor of medicine at Harvard Medical School. “It’s really what someone does on average over a long period of time, not what they did this past month, not what they did this past year.”

Previous studies have shown higher alcohol consumption associated with an increased risk of breast cancer. The effects of moderate drinking had not been calculated before.

In this study, funded by the National Institutes of Health, researchers found a 10% increase in risk with each 10 grams (3.5 ounces) per day of alcohol consumed. For example, women who consumed 3-6 glasses of wine per week had a breast cancer risk about 1.15 times higher than women who don’t drink.

There was no difference in cancer risk among wine, beer and liquor when the amount of alcohol in each was considered. Wine has 11 grams of alcohol per 4-ounce serving; beer, 12.8 grams per 12-ounce serving; liquor, 14 grams per standard serving.

Women who drank less than the equivalent of three glasses of wine per week showed no increased risk for breast cancer, the study found.

Chen said the studied showed alcohol added to whatever risk a woman already had for breast cancer. For example, if a woman had a family history of breast cancer, higher alcohol consumption added to that risk, she said.

Because moderate drinking has been associated with a lower death rate for heart disease, Chen said women should weigh the risks and benefits of drinking based on their own health histories.

Chen and her colleagues found no difference in risk based on what point in life the alcohol was consumed.

“Our results highlight the importance of considering lifetime exposure when considering the effect of alcohol” on cancer risk, the study concluded.

Chen and her colleagues used data from The Nurses’ Health Study, which began following more than 120,000 nurses in 1976 and first began asking participants about alcohol consumption in 1980. The researchers compared drinking habits with the 7,690 cases of invasive breast cancer among the nurses being followed.

    Well not sure what this latest report means...never drank – and had BC at 46. Lucky it was found on a mammogram.
    No family history. Not overweight. 14 years later celebrating each day – stopped asking why a long time ago.

      Yes, you should not ask why. You did nothing to deserve to get cancer. I get tired of science's goal to find a reason that women give it to themselves via behavior. Ever notice how they never do that with prostate cancer and men?

      DJ, one reason you do not see much science relating to prostate or testicular cancer is that breast cancer research receives far more funding.

      If there is more funding, there is more research, and therefore more articles.

      Think about this: How many people on TV where a brown ribbon for prostate cancer? Why does the NFL spend the whole having players where pink for breast cancer?

      You are correct, MS, but that is the fault of men. Women decided to raise tons of money for breast cancer while men sit there and do nothing. If they can make the NFL wear pink, then that shows that men should hire women to run the prostate cancer drive for research money.....

      The report does not mean that all cases of breast cancer are caused by alcohol consumption or even related to it. Therefore women who do not drink at all could still get breast cancer. (And women who do drink could also end up never having breast cancer.) Alcohol simply increases your risk.

      All of these food studies wind up contradicting themselves eventually. Remember when eggs and potatoes were bad for you? Now eggs in moderation have high levels of antioxidants, and potatoes have potassium to counteract the salt in our diets. So we're now supposed to eat both.

      I pretty much give up on listening to the food studies and just try to get my 5 fruits & veggies a day in at least.

      Yea, Ryan, that linked article even contradicts itself. And then at the end it says –> "I think there's enough data to say that drinking a small glass of wine a day is good for you," he says.

      So it still concludes with 1 drink a day is good. Unlike this article says the opposite. That's all I am saying.

      It's all about moderation as Willow said. 🙂

      Given that men have been in industry longer than women, and men get breast cancer, it would have to be something more than just exposure to industrial contaminants. It would be very complicated looking at this with hormones, etc.

    The problem with studies like this (and why they are essentially worthless) is that they say nothing about the underlying risk for breast cancer of the women in the study. Do the women who have higher underlying risk have a tendency to drink more? Do women who drink more also coincidentally expose themselves to higher environmental risk factors (e.g., smoking, drug use, carelessness, whatever, etc.). Only if women with equal risk factors, both genetic and environmental, are followed prospectively and the only differences between the two populations of women is that one population drinks more than the other AND has higher incidence of breast cancer, can we really conclude that there's a causal relationship between drinking and breast cancer.

      Exactly. I think time and research will show us that single factors are rarely the only reason for disease. It's like diet and food. We all seem to want single "fixes". Eat this food, loose weight. Eat this food, protect yourself from cancer. Drink this tea, live longer. I find it difficult to believe our bodies are this simplistic. Next month another study may turn up indicating that moderate drinking decreases your risk for breast cancer.

    Frankly, the data change daily. It could be that, with some women, the more they drink the more risky their behavior is in other ways. The REAL cause of cancer is that the immune system doesn't recognize the aberrant cells, and therefore leaves them alone to multiply and cause tumors. It seems to me that the issue is less with alcohol unless they can show that alcohol messes up the immune system to allow it to not recognize the bad cells.

    I personally believe two big general risk factors are drinking unfiltered tap water & consuming too much animal fat, particularly from red meat. Ten annual mammograms (over a 10 year period) SUPPOSEDLY increases breast cancer risk by 10%, esp. for premenopausal women. Simply suggest every woman consider independently investigating & researching this information. Ultimately, each woman determines what's best for themselves. Many in the medical community probably believe any potential risk increase from mammograms doesn't outweigh their benefit, esp. since the cancer will be detected on the x-ray anyway.

      That number of 10% is very inaccurate. All cancer risk numbers from low dose radiation exposure are estimated from existing data and assuming a linear no threshold relationship. Although inaccurate to state it would be any individuals person excess risk, the increased risk from 100 total mammograms would be less than 0.5%.

    No one ever deserves to get cancer however, there are causes of cancer. Some are known, some not. Some are within our personal control, only if we know about them. Some are not at all within our control, regardless. The cause or causes exist, whether identified or not identified.

      And this is why Americans need more education. This study does not contradict previous studies. A number of studies show an increase in breast cancer risk in women from alcohol consumption, even moderate amounts, but a number of studies show a heart disease benefit. This is not a contradiction.

    I am a scientist and there's one point I thought I should clarify after reading some of the comments about this article and that's that studies like this are purely correlative and do not imply causation at all. So this study finds a correlation between drinking and breast cancer, but the people who did the study are not implying that drinking causes breast cancer. Also studies like this do not at all suggest that everyone who drinks will get breast cancer or that everyone who gets breast cancer drinks/drank. Interest from the general public in topics like this is great, and medical research can always benefit from more funding, so donate if you can. Especially now in the current economic climate, there are many smart people with good ideas that they are unable to test due to lack of money.

      I understand what you are saying overall, but basically your comment says that this study showed nothing. It probably only showed that some women who get cancer drank more than 3 drinks a week, which would not be an uncommon thing. Since breast cancer is common, having it occur in a group of people where a trait/characteristic is common, not much is proved, right?

      I agree this is not a game changing discovery, I can't understand how the media chooses which results to highlight. I went to a lecture today by a brilliant person who has developed a very promising way to predict and possibly prevent breast cancer metastasis, and there are lots more promising and interesting findings that the media ignores. However this result is not useless, correlations are often valuable as a starting point, and in human studies sometimes they're as good as we can do. It's true that drinking is common and breast cancer is relatively common so it won't be hard to find overlap, but what this study did is categorize people based on how much they drink, and then they saw a greater percent of people who drank regularly developed breast cancer compared to people who drank less. It's hard to draw a conclusion from that, it's certainly possible, as someone mentioned, that people who drink regularly also tend to do other things which increase cancer risk (like smoke, etc) and so the difference they found is not directly due to alcohol consumption. But of course the other possibility is that alcohol does increase breast cancer risk. Since this study was done on over 100,000 people, it will like spur further research into the relationship between alcohol and breast cancer which may or may not help with treatment and prevention in the future. So correlative studies like this don't prove anything but they provide hints as to what avenues we might want to look at more closely. Again, I don't know why they chose to write an article about this particular study.

    Statistics are maddening. Isn't it possible that these same women have other risk factors?
    Did most live in cities so as to have environmental exposure? Urban women may be likely to drink more as they are more likely to be childless. Did they live on or near farms, exposing them to a different hazard? Were they on similar birth control method? One can go on and on.
    I get so tired of statistics. When a project is funded to meet certain conclusions those conclusions are met. And why don't they ever run these studies on men?

    The American Cancer Society estimates that the risk of a woman developing breast cancer in her lifetime is 13%. The study quoted by CNN indicates a 10 percent increase in risk if you have a drink every day. That means that your risk increases from 13% to 14.1% (not from 13% to 23%). As well, the study does not state a chemical causal relationship between the drink and the cancer result, only that a statistical relation exists. Other studies show that drinking fluids with anti-oxidants (among them, wine) reduce the risk of heart disease, and heart disease is the number one killer of women(25.8%). *All* cancers come in second, at 22% (lung cancer accounts for 11%, breast cancer for 7%, and colorectal cancer for 4%). So be careful when jumping at something CNN serves up.

Unless you carry the gene, then you should drink even more because you'll probably get it sooner or later and you'll need to brace yourselves. That's what I would do if I found out I carry the gene.

    Okay, let's do the math. Let's say you have a fairly high risk of breast cancer, 1 in 8. That is 0.125 or 12.5%. 1.15 times that increases your risk to 14.3 percent. Less than 2 % increase. That is trivial. Other lifestyle choices (exercise, weight, foods) I'm sure affect risk far more than this. Poor me a glass please, I'll go to my exercise class tomorrow and have leafy greens for lunch.

      The first part of your statement is correct. For the wine, take the part of wine that is good for you and leave out the alcohol. Basically alcohol in any amounts larger that a sip becomes difficult for the system do deal with. Stick with eating food and leave out the chemicals and additives and all that stuff the food industry markets to support their business model.

    if a woman drinks the same amount as a man, she's more likely to develop liver-related disease, says Sharon C. Wilsnack, Ph.D., a clinical psychologist specializing in substance abuse at the University of North Dakota School of Medicine and Health Sciences in Grand Forks.
    Although the lower water content of women’s bodies may be to blame, experts also have two other theories:
    They break down acetaldehyde – a toxic byproduct of alcohol – more slowly, which means it sticks around longer and damages the liver.
    Women's higher levels of estrogen make some liver cells more sensitive to alcohol's toxic effect.
    Women drinkers are also more likely to get stomach ulcers, which can lead to infection, bleeding or even rupture.
    2. Cancer
    The ongoing British Million Woman Study found that as little as one alcoholic drink a day may increase their risk for cancers of the liver, rectum, mouth, throat and esophagus.

    The Nurses Health Study has some sever limitations....There is a correlation between breast cancer and the consumption of animal protein....to see some of the politics of cancer research and diet, read The China Study by Campbell

    So once up a time a drink a day was good for your immune system and reduced the risk of heart disease....NOW it's been reported that it increases the risk of breast cancer in women....Too Drink or not to drink, that's the question.

      Craig, I know. Somehow, we are managing to ignore an entire population. Who can keep up? Next week, spinach will be the cause of breast cancer!

    It's very odd that we never hear about studies done on breast cancer and a women's exposure to xenohormones. You would be shocked to find out how many things we use on a daily basis that expose us to xenohormones. If you don't believe me, LOOK IT UP for yourself.

    These studies are such a waste of money and time - everyone I know who got cancer was a no – drink, drugs, smoking person. No, I don't advertisie their use, just noting the obvious - no one really knows what causes cancer. (except that genetic may play some role)

    So I can choose to drink and end up with breast cancer or I can choose not to drink and end up with heart disease.

    How about this, I'm gonna die one regardless of the cause, so I will live my life the way I choose to.

    Cancer cells are not the enemy. A new theory equates them to immature red and white blood cells. If interested please read Schiel KA. An etiologic model proposing that sporadic adult-onset carcinoma is extramedullary hematopoiesis. Medical Hypotheses (2006) vol. 67, pages 93-109.

    I had a very dear sister-in-law die from breast cancer at the age of 40. She was both a heavy drinker and a smoker, and i've always believed these two factors certainly contributed to her illness. It always breaks my heart that she died when her first grandchild was less than a year old.

      Having your children too young may also be a factor.
