The belief that wearing a tight bra, particularly for long hours, can increase the risk of breast cancer continues to circulate on social media . In an interview with HT Lifestyle, Dr Seema Jagiasi, cancer physician at MOC Cancer Care, Mumbai, explains what women should know about wearing the wrong size.

But current scientific evidence does not support this claim. “There is no established scientific evidence that wearing a tight bra causes breast cancer. The American Cancer Society states that there is no scientific or clinical evidence showing that wearing a bra changes breast cancer risk. This distinction is particularly important in India, where breast cancer is increasingly diagnosed in women at relatively younger ages. “Wearing a tight bra may be uncomfortable, but current evidence does not show that it causes breast cancer .

This includes findings from a 2014 study involving more than 1,500 women. The Indian Council of Medical Research notes that breast cancer incidence increases with age, while Indian studies have reported many patients presenting between 45 and 50 years of age. Because a bra is tight,” Dr Seema highlighted, the lymphatic system is not a drainage pipe that gets blocked simply.
Breast health is better protected by understanding genuine risk factors, following appropriate screening advice and getting unusual breast changes checked promptly,” said Dr Seema.
The National Cancer Institute identifies increasing age as the most important risk factor apart from being female. That does not mean the fit of a bra is irrelevant. A bra that is too tight can cause discomfort, pressure marks, skin irritation , chafing, or pain, particularly in women with larger breasts or sensitive skin . During periods of breast tenderness, pregnancy or breastfeeding, breast size and sensitivity can also change, making a well-fitting bra more comfortable. But discomfort should not be confused with cancer risk. The American Cancer Society lists bras among factors that have not been shown to increase breast cancer risk. A new breast lump, nipple discharge, nipple inversion, unexplained change in breast size or shape, or persistent skin changes should be evaluated by a doctor rather than attributed to clothing.
Factors include increasing age, family history, inherited gene changes such as BRCA1 and BRCA2, reproductive and hormonal factors, excess body weight, alcohol consumption, physical inactivity, and certain radiation exposures, according to Dr Seema. More importantly, women should not allow fears about bras, deodorants, or other commonly circulated “cancer-causing” claims to distract them from genuine risk factors and breast health awareness.
