Is it common for trapezius to become enlarged in women with very heavy breasts? (Photo)

It is hard to say whether or not this is from you breasts. It is not something that is classically described as a result of large breasts. I would base my decision to have a breast reduction on other factors such as neck pain, shoulder strain and back pain and lastly but most importantly, your desire to have smaller breasts.

Hello good day, in some cases your trapezius muscle may get larger from the weight of your breasts. Once the weight is reduced, I think the muscles will decrease in size. However, the best thing is to meet with a plastic surgeon and discuss your goals of treatment.
