Breast reductions are performed to make smaller breasts. The secondary benefit is that patients often get relief of neck, back, and shoulder pain, bra strap grooving, and intertriginous rashes from reducing their large pendulous breasts.
Bra size is a very rough guideline in that there are no manufacturing standards for bras and no guarantee that the patient has been fit correctly to begin with.
During a consultation for a breast reduction, I promise my patients 2 things:
1. They will have smaller breasts when I am done
2. Their breasts will NOT be symmetrical. I try to get them as close as possible but there will always be slight differences in volume, nipple position, etc. If you look at your own breast you can probably see some difference in the size and shape when you compare one side to the other.
Insurance guidelines are as follows:
1. Documented symptoms of large breasts (see above). Duration of symptoms.
2. Documentation of methods of relief:
--What pain medications has the patient tried?
--Has the patient been to another health professional ie. physical therapist, chiropractor, neck surgeon?
--Has there been weight loss? How much?
--Any documentation of stetching, excercise, weight training to help alleviate these symptoms
3. Physical parameters
--Height, weight
--Schnurr Scale then estimates the amount of tissue that needs to be resected based on a body surface area calculation that is dependent on your height and weight.
In your case, the only factor that we can consider is your height and weight. Plugging them into the Schnurr scale for 5"4" 260lbs comes out with a required resection of at least 1075 grams (roughly 2.3 pounds each breast). You have to have at least this much taken off if you want insurance coverage.
You should be seen in consultation by a board certified plastic surgeon so you can hear about all of the risks and benefits of surgery and have a thorough examination.
Best of luck with your endeavors.
