Would it be fitting to have a breast reduction?
I have 32 D breasts. I feel like my breasts are causing back and neck problems and I feel like it contributes to my poor posture; I don't remember being this way until they stopped growing. My shoulders are curved forward and my back seems hunched.. In fact my grandmother and mother seem to look like this as its a hereditary thing. I'm only 5'3 weighing at 105 lbs.
I believe based on the information about your size that a breast reduction would be an appropriate procedure. I would suggest you get a consultation with a board certified plastic surgeon to find out more about the procedure.
From the information you have provided, you might be a good candidate for a breast reduction. You should setup an appointment with a board certified plastic surgeon to see if you are a good candidate and to explore your options.
