 Binding for extended periods of time can lead to rashes or yeast infections under the breasts, back or chest pain, shortness of breath, overheating, or fractured ribs.Unsafe binding may lead to permanent deformation of the breasts, scarring, and lung constriction and long-term binding may adversely affect the outcome of a future mastectomy.In one study, 97.2% of those surveyed had some sort of health problem caused by binding.
