At 5’5” and 130 lbs, a 560 cc implant would generally be considered a relatively large implant. Whether it will make you look “top heavy” depends on several factors, including your chest width, shoulder and hip proportions, your existing breast tissue, the implant profile, and the surgical technique. Some women with a broader frame achieve a balanced result with this size, while on a smaller frame it can appear more prominent. Another important consideration is the long-term effect of implant weight. A 560 cc silicone implant is significantly heavier than a smaller implant, and the additional weight places greater stress on the skin, breast tissue, and supporting ligaments. Over time, this may increase the likelihood of breast ptosis (sagging), tissue stretching, implant descent (“bottoming out”), or the need for revision surgery—particularly if your skin quality is not ideal or if you plan future pregnancies or experience significant weight fluctuations. Ultimately, the best implant size is not determined by volume alone. The implant should be selected based on your breast base width, tissue characteristics, and aesthetic goals while also considering how well your tissues can support it for many years. If your goal is a very full, dramatic appearance, 560 cc may be appropriate. However, if you are hoping for a natural, proportional result with a lower risk of long-term tissue stretching, discussing slightly smaller implant options with your board-certified plastic surgeon may be worthwhile. Be sure to ask your surgeon why 560 cc was recommended over smaller sizes and whether they expect your tissues to support that volume well in the long term. A thorough consultation with measurements and implant sizers is the best way to ensure the result matches both your aesthetic goals and your anatomy.
