For anyone reading this thread who is under the illusion that binding is safe, maybe this study will help.

Here is the abstract
Abstract
Chest binding involves the compression of chest tissue for masculine gender expression among people assigned a female sex at birth, particularly transgender and gender non-conforming individuals. There are no peer-reviewed studies that directly assess the health impacts of chest binding, yet transgender community resources commonly discuss symptoms such as pain and scarring. A cross-sectional 32-item survey was administered online to an anonymous, non-random sample of adults who were assigned a female sex at birth and had had experience of binding (n = 1800). Multivariate regression models were used to identify practices associated with self-reported health outcomes. Of participants, 51.5% reported daily binding. Over 97% reported at least one of 28 negative outcomes attributed to binding. Frequency (days/week) was consistently associated with negative outcomes (22/28 outcomes). Compression methods associated with symptoms were commercial binders (20/28), elastic bandages (14/28) and duct tape or plastic wrap (13/28). Larger chest size was primarily associated with dermatological problems. Binding is a frequent activity for many transmasculine individuals, despite associated symptoms. Study findings offer evidence of how binding practices may enhance or reduce risk. Clinicians caring for transmasculine patients should assess binding practices and help patients manage risk.
From previous posts about this study, here are some snippets. I do remember reading more it once so I wonder if it was infront of the paywall at one stage.
Here are the negative effects in full:
rib fractures, back pain, chest pain, rib or spine changes, bad posture, shoulder pain, shoulder joint ‘popping’, muscle wasting, numbness, headache, overheating, fatigue, weakness, lightheadedness or dizziness, cough, respiratory infections, shortness of breath, heartburn, abdominal pain, digestive issues, breast changes, breast tenderness, scarring, swelling, acne, itch, skin changes and skin infections.
Now the paper recommends reduction in hours and days per week for ‘safety’. While also making statements about clinicians working with patients to make these reductions of negative side effects by referring the patient for a double mastectomy. These were adults in the study not children. However. It seems remarkably negligent considering the very permanent life limiting impacts of double mastectomies on female bodies. Yet the study recommends it as an alternative to binding.
So, I would be seriously sceptical of any poster who dismisses that potential harm of binders.
