If your breasts are heavy, painful, or putting strain on your shoulders, neck, or back, talk to your doctor. In some cases, they may recommend breast reduction surgery or other treatments to help relieve discomfort related to the size of your breasts. If you are interested in getting breast reduction surgery, your insurance company may cover the procedure if the amount of breast tissue to be removed exceeds a certain weight (usually about 500 grams (18 oz)). If need to get an accurate measurement of your breast weight, your doctor may be able to get a good estimate using imaging techniques. For example, they might do an MRI, a CT scan, or a mammogram to estimate the volume and density of your breasts. From there, they can get an estimate of your breast weight. Imaging tests can be costly, and they also come with some risks, such as radiation exposure. As an alternative, some doctors use the Archimedes method, which is based on water displacement, to estimate the volume of the breast. From there, they can also get an estimate of the weight of your breast.  The accuracy of the method will depend on a variety of factors, including the size and shape of your breasts and body and how easily you can fit your whole breast into a container of water. Your doctor might also recommend other methods, such as taking a cast of your breast and estimating the volume and weight based on that.
