Wearing A Bra At Night

Can Deodorants Cause Breast Cancer

According to an older study from 2000, wearing a bra or other tight fitting garment at night could affect a persons sleep-wake cycle.

The researchers found that nighttime pressure from tight fitting garments caused an increase in core body temperature and a decrease in melatonin. Melatonin is a hormone that helps regulate the sleep-wake cycle. A decrease in melatonin can affect sleep quality.

This small scale study monitored 10 participants over a 58-hour period. Further research involving more participants and a longer study duration is necessary to support the findings.

  • What Is Known About The Ingredients In Antiperspirants And Deodorants

    Aluminum-based compounds are used as the active ingredient in antiperspirants. These compounds form a temporary plug within the sweat duct that stops the flow of sweat to the skin’s surface. Some research suggests that aluminum-containing underarm antiperspirants, which are applied frequently and left on the skin near the breast, may be absorbed by the skin and have estrogen-like effects .

    Because estrogen can promote the growth of breast cancer cells, some scientists have suggested that the aluminum-based compounds in antiperspirants may contribute to the development of breast cancer . In addition, it has been suggested that aluminum may have direct activity in breast tissue . However, no studies to date have confirmed any substantial adverse effects of aluminum that could contribute to increased breast cancer risks. A 2014 review concluded there was no clear evidence showing that the use of aluminum-containing underarm antiperspirants or cosmetics increases the risk of breast cancer .

    Are Men Less Likely To Get Breast Cancer Because Antiperspirant Gets Caught In Their Underarm Hair And Is Not Absorbed By Their Skin

    Men are much less likely than women to develop breast cancer, mostly because men have much less breast tissue than women. Women have about 100 times more breast tissue than men and are about 100 times more likely to develop breast cancer.

    Hormones also play a role. Men with metabolic or genetic conditions that lead to increased estrogen levels have an increased risk of developing breast cancer.

    Underarm hair and antiperspirant absorption have not been linked to male breast cancer risk.

    For The Longest Time Weve Heard That Deodorants Cause Breast Cancer But Is There Any Truth To It Dr Tanaya Narendra Famously Known As Dr: Cuterus On Instagram Tells Us All About It

    Can Deodorants Cause Breast Cancer?
    Listen to this article

    Rumours and misinformation are rampant, especially in the world of health and fitness. And if theres one thats been floating around for generations it is that deodorants cause breast cancer. This is exactly what Dr Tanaya Narendra aka dr_cuterus speaks about in her latest post on Instagram. As always, she has busted a myth to educate her audiences, and make them more informed choices.

    Heres what she wrote in her Instagram post, Im sure youve heard of this rumour that #deodorants cause breast cancer. Im even more sure youve seen some brand selling pretty expensive #natural or #aluminiumfree deodorant. There is nothing wrong with buying and using naturally derived products , but dont let yourself be fooled into #bullshit reasons for why you should buy the more expensive product. Understand the science, and protect yourself from being befooled.

    Heres why this rumour is false

    This claim is absolutely FALSE. Dr Narendra says that lymph nodes are a part of the immune system they help your body filter the microbes and bad guys . Lymph nodes are connected to each other using a superhighway inside your body, but they are not connected to your sweat glands. Antiperspirants block your sweat glands, and not your lymph nodes.

    To really purge your body from aluminium, youll need to do a lot more like saying goodbye to aluminium foil and cookware. Also, tobacco and marijuana are known to contain aluminium, she adds.

    Can Deodorants And Antiperspirants With Aluminium Cause Cancer

    Is this something we should be concerned about or is it just a myth?”

    There is no evidence to support the claim that deodorants or antiperspirants cause cancer. This link was first suggested in an email hoax, and rumours have circulated ever since. Typically, scare stories suggest that aluminium in antiperspirants prevents us from getting rid of toxins in our sweat, which clog up lymph nodes and lead to breast cancer. But the details of this are wrong.

    First, sweating does help your body get rid of toxins. Second, breast cancer starts in the breast and spreads to the lymph nodes, not the other way around. Third, there is no evidence that aluminium can lead to cancer. Some reports occasionally claim to have found aluminium, or other deodorant chemicals, in samples taken from breast tumours. But they usually involve a very small number of women, and they never compare levels of aluminium in the tumours to levels in other parts of the body, or to women who dont have breast cancer. Without this information, these reports tell us nothing about deodorants and breast cancer risk. On the other hand, one study looked at 1600 women and found that those who use deodorant are no more likely to develop cancer than women who dont.

    The Role Of Antiperspirant In Causing Breast Cancer Is Not Proven

    The main cause of breast cancer is the use of antiperspirant.

    Our verdict

    Cancer Research UK says that at present theres no convincing evidence that using deodorants or antiperspirants affects breast cancer risk.

    What was claimed

    Men are less likely to develop breast cancer because antiperspirant deodorant is applied to the hair rather than directly on to the skin.

    Our verdict

    Men are less likely to develop breast cancer due to differences in the amount and type of breast tissue in men. There are also important hormonal differences between men and women which relate to this.

    A widely shared post makes a number of false or unevidenced claims about the link between breast cancer and the use of antiperspirant deodorant.

    Cancer Research UK told Full Fact that there was no convincing evidence to support the claim that breast cancer and antiperspirant deodorant use are linked.

    Using antiperspirant deodorant is not the main cause of breast cancer

    The main claim in the Facebook post is that antiperspirant deodorant is the main cause of breast cancer. This isnt true.

    Since as early as 2002 , theories have circulated which link breast cancer to antiperspirant deodorants that contain aluminium. This has been linked to anincrease in the percentage of breast cancers occurring in an area known as the upper outer quadrant of the breast, near the armpit. As a result, scientists and epidemiologists began to consider whether a lifestyle factor may be the cause.

    Could There Be A Link To Inherited Susceptibility To Breast Cancer

    Development of breast cancer through the inheritance of genetic susceptibility is associated with loss of function of tumour suppressor genes including the BRCA1 and BRCA2 genes, which results in impaired DNA repair processes . The increasing penetrance of these genes in Iceland, however, has suggested that underlying mechanisms of susceptibility can also be influenced by environmental factors as well as genetic factors . Although it is possible that cancers result in these susceptible people from an inability to repair random replication errors, it is also possible that these people are more susceptible to damage from genotoxic pollutant chemicals, including those absorbed from cosmetic products applied around the breast area, than the remainder of the population who have intact DNA repair systems .

    But What About Parabens

    Can Deodorant Cause Breast Cancer?

    Of course, unlike the case among antivaccinationists, where aluminum fears supplanted mercury fears, in terms of breast cancer aluminum fear mongering is old school. New school is parabens. Parabens are hip. Theyre now. Theyre happening. In fairness, on the surface, there appears to be more of a reason to suspect them as potentially contributing to breast cancer than there is to suspect aluminum-containing antiperspirants. Thats not saying that theres a compelling reason to suspect them, only that there is a modicum of plausibility. Parabens is a term used to describe a series of parahydroxybenzoates or esters of parahydroxybenzoic acid , chemicals most commonly used as preservatives by the cosmetic and pharmaceutical industries because of their bactericidal and fungicidal properties. Theyre found in a variety of products including shampoos, commercial moisturizers, shaving gels, personal lubricants, topical/parenteral pharmaceuticals, spray tanning solution, makeup, and toothpaste. Most major brands of antiperspirant are paraben-free these days, but that doesnt stop them from being examined as a cause of breast cancer. Typical of such articles is one byyou guessed it!Joe Mercola entitled Parabens: 99% of Breast Cancer Tissue Contained This Everyday Chemical :

    So, it would seem, we have a chemical that is widely used as well as a seemingly plausible mechanism to cause breast cancer. Theres a problem, though. As Schwarcz, who is a chemist, also pointed out:

    Whats The Relationship Between Deodorants And Antiperspirants And Breast Cancer

    Whatever time we might spend on thinking about our deodorants and antiperspirants is hoping theyll solve our body odor and sweat issues not worrying about their potentially harmful ingredients and their proximity to our breasts.

    Because of this, scientists have researched and studied the potential connection between deodorants and antiperspirants to breast cancer. Youll be relieved to learn that there is no relationship between these products and breast cancer. Additionally, studies found no increase in skin side effects with the use of deodorants during breast radiation.

    No scientific evidence has been discovered that links the use of these deodorants and antiperspirants to the development of breast cancer.

    Antiperspirants And Alzheimers Disease

    Back in the 1960s, a few studies found high levels of aluminum in the brains of people with Alzheimers disease. The research suddenly called into question the safety of everyday household items such as aluminum cans, antacids, and antiperspirants.

    But the findings of these early studies werenât replicated in later research, and experts have essentially ruled out aluminum as a possible cause of Alzheimers.

    There was a lot of research that looked at the link between Alzheimers and aluminum, and there hasnt been any definitive evidence to suggest there is a link, says Heather M. Snyder, PhD, senior associate director of medical and scientific relations for the Alzheimers Association.

    According to the experts interviewed for this story, the aluminum in antiperspirants doesnt even typically make its way into the body.

    The aluminum salts do not work as antiperspirants by being absorbed in the body. They work by forming a chemical reaction with the water in the sweat to form a physical plug which is deposited in the sweat duct, producing a blockage in the areas that its applied, says David Pariser, MD, professor of dermatology at Eastern Virginia Medical School and past president of the American Academy of Dermatology. Even nicks from shaving, the amount is so negligible that it doesnt make a whole lot of scientific sense.

    What About When Youre Not Sleeping

    Now that you know that sleeping in a bra cant significantly positively or negatively affect your breast health, you might be wondering if the same is true of wearing one during the day. And, despite what many lingerie companies would have you believe, Richardson says that, other than cosmetic issues, there is no reason to think you need to wear a bra in an attempt to avoid more serious breast health concerns.

    So, once again, it comes down to personal comfort. This is especially true if youre bustier. For those with larger breasts, bra wearing can help with back and neck pain, however some point out that posture and whether or not someone shrugs and stoops their shoulders has more influence over back and neck pain than the size and weight of breast tissue itself, Richardson says. Whether we wear a bra or not may make us feel more self-conscious about our breasts and how people see us, which spills into other areas of stance and comfort.

    And, while larger busts are on the brain, its worth mentioning that, as Richardson points out, women with very large breasts may see further benefits, as fabric between the bottom of the breast and the top of the upper abdomen prevents moisture from getting trapped, which could otherwise cause yeast and potentially skin fungi to grow. So, by keeping the cozy barrier, youll be able to reduce any possible skin irritation, which again brings us full circle to comfort.

    Is The Antiperspirant And Breast Cancer Link Just An Internet Myth Created By Confused People

    Deodorant can cause breast cancer

    The potential link between breast cancer and aluminum antiperspirant may have started out as one of those pass it along emails in the late 90s, but the aluminum-breast cancer link has actually been studied for a number of years now. The first published study regarding antiperspirant use and breast cancer risk was in 2002, a population-based study that actually found no correlation between breast cancer and antiperspirant use. However, the next year, a researchers found that earlier and more frequent antiperspirant use did correlate with earlier breast cancer diagnoses, suggesting that aluminum may have been to blame. One thing they did not apparently discuss, however, was that perhaps women who used deodorants earlier in life had been exposed to estrogen for a longer period of their lifespan. The earlier the need for deodorant arose, the earlier puberty and its resulting hormones would have been, and thus higher risk for reproductive cancers. So, that study wasnt able to show direct causation.

    We now know that transdermal uptake of aluminum is not only possible, but may also be important. I am now concerned that we are guilty of being complacent about exposure to aluminum.

    Antiperspirants intended action, obstruction of axillary apocrine sweat glands, could create a reservoir of hormones in an optimal environment for transdermal absorption. Long term inadvertent and unintended systemic hormonal exposure to developing breast and prostate tissue may occur.

    Frequently Asked Questions About Sleep And Cancer Risk

    Does Sleeping With a Light on Increase Cancer Risk?

    Though not conclusive, some research indicates that exposure to artificial light at night may have an effect on cancer risk.

    Darkness is an important contributor to circadian rhythm it induces the body to produce melatonin, a hormone that facilitates sleep. Beyond its sleep-promoting benefits, melatonin has been found in animal studies to fight tumor growth and help repair DNA damage in cells. Theoretically, then, sleeping with the lights on may interfere with normal circadian signals and create conditions more permissive of cancer development .

    In an observational study of people and their artificial light exposure at night, sleeping in a highly illuminated bedroom was associated with an elevated risk of prostate cancer but a . Given these inconsistent findings, considerably more research is needed about light during sleep to determine whether or not it is a significant risk factor for cancer.

    Can You Get Cancer by Sleeping Next to Your Phone?

    There is no evidence that sleeping next to your phone increases your risk of cancer. The type of energy from cell phones, called non-ionizing radiation, does not cause DNA damage instead, its only established biological effect is heating. Studies of cell phone users have not found any consistent pattern of elevated risk of brain tumors or any other kind of cancer.
