I am 5’4, my bra size is 36C, my breasts feel like they’re cinder blocks on my chest. should I consider a breast reduction?

This size is generally not considered "large". I would recommend consulting with a plastic surgeon to determine what options are available to you .

Hello and thank you for your question.
It is hard to answer your question with out seeing you in person. Schedule a consultation with a board certified plastic surgeon to discuss your options. Best of luck!

The best way to determine what your breast size should be with respect to your anatomy and give true advice would be a discussion with a board certified plastic surgeon. Not only does proportion depend upon the aesthetic balance of your breasts with your shoulders, waist, hips, and buttocks, but also upon your objectives, lifestyle, soft tissue quality, muscular anatomy, and long-term concerns. A breast reduction also includes a breast lift. There is also a limit to how small you can go due to tissue that needs to be retained for the nipple/areola to maintain a good blood and sensory nerve supply. A PS cannot guarantee that a breast will be a specific cup size after reduction. Very large breasts rarely are reduced by more than two or three "cup" sizes. I never promise a cup size because bras manufacturers do not follow a standard size.
