Does Sleeping On Your Stomach Cause Breast Cancer

Can Sleeping Posture Predict Your Personality

Does Sleeping in a Bra cause Breast Cancer?

That depends on what you consider “personality.” In the 70s and 80s, some researchers claimed they could use sleeping postures to predict if someone were impulsive, feminine, anxious, self-confident–even whether they could be hypnotized.

More recent studies have cast doubt on these theories. The research has been criticized for using “woefully small” numbers of sleepers. Many contradictions have been found between these studies as well.

A more recent attempt to associate personality traits to body positions during sleep came up empty-handed. It showed only a “very weak relationship between sleep positions and personality,” and, using predictions from earlier models, failed to reliably predict the participants’ personality traits.

But on the Other Hand…

Even if earlier studies are unreliable, there may be another way that our sleep postures say something about our personalities. Some sleeping positions are associated with well-rested sleepers. Maybe people who prefer them wake up less crabby and irritable, and are more alert during the day.

Here are some examples, using the Big Five personality traits. A group of 22,000 American and Japanese adults were measured over 10 years. The ones who slept poorly tended to become less conscientious over time. The ones who slept best were the most extroverted and the least neurotic.

So, at the end of the day, the best sleeping position for you may simply be the one that leaves you feeling your best the next day.

Myth: Wearing Antiperspirant Increases Your Risk Of Getting Breast Cancer


The American Cancer Society pooh-poohs this rumor, but admits that more research is needed. One small study did stumble on traces of parabens in a tiny sample of breast cancer tumors. Parabens, used as preservatives in some antiperspirants, have weak estrogen-like properties, but the study in question made no cause-and-effect connection between parabens and breast cancer, nor did it conclusively identify the source of the parabens found in tumors.

Myth: If You’re At Risk For Breast Cancer There’s Little You Can Do But Watch For The Signs


There’s a lot that women can do to lower their risk, including losing weight if they’re obese, getting regular exercise, lowering or eliminating alcohol consumption, being rigorous about examining their own breasts, and having regular clinical exams and mammograms. Quitting smoking wouldn’t hurt either. Some high-risk women also choose to have a prophylactic mastectomy to decrease their risk by roughly 90%. They can take other proactive steps such as having regular MRIs, exploring chemoprevention with treatments such as tamoxifen, and participating in clinical trials.

Data extraction

Statistical analysis

Our meta-analysis compared breast cancer risk for short and for long , versus referent sleep duration . The referent sleep duration group was similar to that used in other studies, except for Cao et al., Shen et al., and Wu et al. where the baseline category was switched using the generalized least squares method . In studies where multiple categories of short or long sleep were available , a single estimate was obtained using the generalized least squares method . We re-estimated RRs of breast cancer for < 7, 78, > 8 h of total sleep duration in the Million Women Study for the whole follow-up period and for the follow-up period with the first 5 years excluded, respectively. The meta-analysis calculated the inverse-variance weighted average of study-specific log RRs, which avoids giving disproportional weights to small-scale studies. Heterogeneity was assessed by Cochrans Q test.

All statistical tests were two-sided. STATA 15.1 was used for all analyses and R for plotting forest plots.

Can Squeezing Or Being Hit In The Breast Cause Cancer

An injury, such as falling or being hit in the chest, will not cause breast cancer. Squeezing or pinching the breast or nipple will not cause breast cancer either.

It may cause bruising and swelling to the breast, which can be tender or painful to touch.

Sometimes an injury can lead to a benign lump known as fat necrosis. This is scar tissue that can form when the body naturally repairs the damaged fatty breast tissue.

Will Sleeping In A Bra Prevent Breasts From Sagging

Good news if you sleep braless: sleeping in a bra doesnt actually prevent your breasts from sagging later on, according to the experts.

There is a myth that if you dont wear a bra, your breasts will sag, said Dr. Bishara. Breast sagging is caused by aging and gravity. Whether you wear a bra to sleep or not will make no difference. As we age, there is weakening of connective tissue fibers in the breasts, and with the effects of gravity, some sagging is inevitable. The heavier your breasts, the harder the pull of gravity. While bras can shape and lift your breasts while wearing them, they have no effect on long-term prevention of breast sagging.

Dr. Ramanadham agreed, saying, Sleeping in a bra will not prevent normal changes that we see with aging, such as sagging of the breast.

Lack Of Sleep Linked To Higher Risk Of Recurrence Of Estrogen

Cancer Symptoms and Signs In Men or Women

A small study suggests that not getting enough sleep may be linked to a higher risk of recurrence of early-stage, estrogen-receptor-positive breast cancer in postmenopausal women.

The study was published in the August 2012 issue of Breast Cancer Research and Treatment. Read the abstract of Association of sleep duration and breast cancer Oncotype DX recurrence score.

The Oncotype DX test is a genomic test that analyzes the activity of a group of 21 genes that can affect how a cancer is likely to behave and respond to treatment. The test is done on a breast cancer tissue sample. The Oncotype DX test is used to help doctors figure out a womans risk of early-stage, estrogen-receptor-positive breast cancer coming back, as well as how likely she is to benefit from chemotherapy after breast cancer surgery.

Oncotype DX test results assign a Recurrence Score a number between 0 and 100 to the early-stage breast cancer. Based on your age, you and your doctor can use the following ranges to interpret your results for early-stage invasive cancer.

What Causes Breast Pain

If your boobs hurt, your mind may jump right away to the C word. But chances are slim that breast pain is breast cancer.

Breast pain alone is rarely, rarely associated with cancer, says Monique Swain, MD, an obstetrician and gynecologist in the breast division at Henry Ford Health System in Detroit.

There are two types of breast pain: Cyclical pain is associated with your period and most often affects both breasts. Noncyclical pain is due to any other reason and doesnt follow a monthly pattern. It can affect one or both breasts, all of the breast, or just part of it.

Most breast pain goes away on its own or can be easily treated. Talk to a doctor if the pain doesnt go away in a week or two or if it gets in the way of normal activities. You should also contact a doctor if you have other symptoms, including a lump thats not related to your period, discharge from your nipple, or signs of infection like redness, swelling, and warmth.

Here are some possible reasons why you have breast pain.

Myth: Only Women With A Family History Of Breast Cancer Are At Risk

Reality: Roughly 70% of women diagnosed with breast cancer have no identifiable risk factors for the disease. But the family-history risks are these: If a first-degree relative has had or has breast cancer, your risk of developing the disease approximately doubles. Having two first-degree relatives with the disease increases your risk even more.

Myth: Wearing An Underwire Bra Increases Your Risk Of Getting Breast Cance

Stomach Sleeping Pros And Cons

Prevents snoring and sleep apnea Causes wrinkles and breast sagKnocks spine out of alignmentCreates pressure on muscles and jointsLeads to back and neck pain

Experts agrees: sleeping on your stomach is a bad idea. While it can prevent snoring and sleep apnea , it does so at the cost of everything else.

Much of your body weight is centered at your center, literally. When you sleep on your stomach, your core sinks deeper into the mattress while your limbs and head stay higher up on the surface, wreaking havoc on your spinal alignment and causing neck and back pain.

Meanwhile, the pressure of your body increases the pressure on your muscles, joints, and organs. As a result, you spend more time shifting positions during sleep, as your body tries to stay comfortable, leading to more disturbed, lower-quality sleep.

If youre overweight or sleep on a softer mattress like memory foam, all of these negative effects are intensified.

Oct. 1, 2003 — A new study shows that how well you sleep may determine how well your body fights cancer — and may help explain how mental well-being plays into cancer recovery and progression.

After analyzing previous studies, Stanford University psychiatrist David Spiegel, MD, and colleague Sandra Sephton, MD, say that sleep problems alter the balance of at least two hormones that influence cancer cells.

Theres no conclusive evidence that exposure to chemicals in the environment increases your risk of breast cancer.

Lots of studies have looked at the relationship between breast cancer and chemicals in the environment such as pesticides, traffic fumes and plastics, but theres no clear evidence of any links.

It can be very difficult to work out the effects of individual chemicals when we are exposed to low levels of thousands of chemicals during our lifetime.

Some studies have suggested that women who are exposed to chemicals in their jobs, for example in the manufacturing industry, may be at higher risk of breast cancer. But the evidence is weak and more research is needed. Employers are legally required to limit exposure to chemicals that may cause cancer.

Myth: Annual Mammograms Expose You To So Much Radiation That They Increase Your Risk Of Cancer


While it’s true that radiation is used in mammography, the amount is so small that any associated risks are tiny when compared to the huge preventive benefits reaped from the test. Mammograms can detect lumps well before they can be felt or otherwise noticed, and the earlier that lumps are caught, the better one’s chances for survival. The American Cancer Society recommends that women age 40 and older receive a screening mammogram every one to two years.

Make Your Own Choices But Wear The Right Bra

Bra wearing while you sleep boils down to a personal choice and is a matter of comfort. You dont need to worry about your decision from a health or medical standpoint unless a support bra has been recommended after surgery. In this case, wearing one is a good idea.

The key to avoiding any complaints or discomfort from wearing a bra to sleep is to choose the right bra for the right occasion. So a tight underwired bra isnt a smart choice for sleeping. On the other hand, a soft support bra with no underwire or a sports bra for extra support may work for you. If you find yourself waking up with red lines or indentations on your skin from your bra, you need to be fitted for a new one thats the right size. A good bra will provide you support, not pain or irritation.
