Wearing an Underwire Bra All Day? Doctor Explains If It Impacts Breast Health

You must have heard how underwire (padded) bras may have harmful effects on breast health. In fact, there was once this popular belief that these bras are linked to breast cancer. While studies have debunked the cancer myth, one question remains: can underwire bras harm your breast health in other ways or are they completely safe as daily wear? Today, we have attempted to dive deeper into the topic and share a detailed answer with you. Read ahead.

Let us take a look at what Dr Lavanya Kiran, Director and Lead Consultant, Obstetrics, Gynaecology, KIMS Hospitals, Electronic City, Bengaluru, has to say about this.      

Does Wearing an Underwire Bra for Long Hours Harm Your Breast Health?

Dr Kiran says that prolonged wearing of underwire bras will not affect breast well-being, neither will it cause breast cancer. “However, excessive wearing of the tight or ill-fitted underwire bra may bring about discomfort and other problems of the skin,” she adds. On this note, the expert shares some side effects of wearing underwire bra for long hours:

• Skin irritation: The constant rubbing of the wire in the bra can cause redness, chafing, rashes, or tenderness, especially in humid and hot conditions.
• Pain in the breasts and chest: This may occur due to the underwire pressing on the breast and chest area.
• Pressure marks: A tight bra may result into formation of deep lines on the skin causing swelling or irritation.
• Shoulder and back pain: An improperly fitted bra, which may be tight without enough support, may lead to shoulder and back pain.
• Discomfort due to restriction: A bra that is worn tightly for a long period can cause difficulty in breathing or movement, but it does not harm the breast tissues permanently.
• Breast sensitivity: Women who suffer from mastalgia or breast tenderness during their menstrual cycle experience discomfort while wearing an underwire bra.

“However, it is the fit that is the problem here, not the underwire itself. Get the right bra size in terms of both the band and the cups, and make sure the underwire is around the tissue and not directly over it. Never wear an underwire that digs into your skin or that is damaged. If persistent breast pain, a new lump, nipple discharge or skin changes occur, they should be evaluated medically rather than attributed to the bra,” concludes Dr Kiran.

Can Bras With Underwire Cause Breast Cancer?

A 2014 study, published in the journal Cancer Epidemiology, Biomarkers & Prevention, stated that for years, rumours and internet myths have circulated that wearing a bra can increase a woman's risk of developing breast cancer. Many of these myths specifically blamed underwire bras, claiming they restrict the drainage of lymph fluid around the breasts. These popular claims noted this restriction traps dangerous toxins in the breast tissue. This can supposedly lead to the development of breast cancer. 

To finally separate fact from fiction, researchers conducted a comprehensive population-based study to examine this specific concern. The study was done by scientists at the Fred Hutchinson Cancer Research Center in Seattle.

A thousand postmenopausal women were interviewed in detail; they were the ones who were recently diagnosed with breast cancer. These patients' habits were compared to a control group of healthy women without breast cancer. The researchers asked the participants in-depth questions related to their lifelong bra-wearing habits. 

The study specifically analysed whether the women regularly wore bras with an underwire and for how many hours daily. After carefully examining all the data, the scientists discovered absolutely no evidence linking bra-wearing to any increased risk of breast cancer. The results clearly proved that women who regularly wore underwire bras had the exact same risk of developing cancer as the ones who wore wire-free bras.

Moreover, the number of hours a woman wore an underwire bra daily also had zero effect on her likelihood of getting breast cancer. The study, therefore, proved that the myth of tight clothing or metal underwires trapping toxins and damaging breast tissue are false.

Conclusion

Wearing an underwire bra for a long duration of time does not increase your risk of breast cancer. However, an ill-fitted one can certainly cause chafing, pressure marks, and physical discomfort. To prevent these issues, first it is important to find your correct size to ensure the underwire frames your breast tissue, instead of digging directly into it. To conclude, pairing a properly fitted bra with a balanced lifestyle and regular medical screenings is the best way to maintain optimal breast health.
