According to a study published in the journal Cancer Epidemiology, Biomarkers & Prevention, a population-based case-control study confirmed no association between bras and increased risk of breast cancer in postmenopausal women.
Breast cancer in developed countries may be more common than in developing countries, and one potential cause is the difference in bra wearing patterns.
The new study found that there is no evidence that wearing a bra will increase the risk of breast cancer in women. After considering how many times a woman wears a bra every day, wearing a bra with a steel ring, or at what age to start wearing a bra, the bra is still not confirmed. Will increase the risk of breast cancer in women.
Some people have suggested in non-professional media that wearing a bra may be a risk factor for breast cancer. Some people speculate that bras may block the excretion of waste around the breast. By now, however, there is only very limited biological evidence supporting the link between wearing bra and breast cancer risk.
According to the authors of the study, the study used a rigorous epidemiological study design to examine the relevance of various bra wearing habits to breast cancer risk. These findings confirm that women wearing bras do not appear to increase the risk of postmenopausal breast cancer.
The study included 454 women with invasive ductal carcinoma (IDC) and 590 women with invasive lobular carcinoma (ILC). IDC and ILC were the two most common subtypes of breast cancer, and 469 women without breast cancer Control. All women are postmenopausal women, aged between 55 and 74.
The researchers conducted face-to-face interviews with demographics, family history, and birth history. They also asked a series of structural questions to evaluate the bra wear pattern. Questions include when the study participants started wearing bras, whether they wore bras with steel rings, the size and bandwidth of her bra cups, the amount of time and days of wearing bras per day, whether her bras were worn at different times. Changed within the paragraph.
The study found that wearing a bra was not associated with an increased risk of IDC or ILC.
