Are implants heavier or lighter than breast tissue?

Hello,Silicone, cohesive gel implants move and feel very much like natural breast tissue. Breast tissue can be made up of variations of glandular tissue and fat with different weight/density but silicone implants tends to feel/weigh about the same. All the best

That depends if the needs a breast lift or not and on the size of implant they want. The bigger the implant the less natural it's going to look. Now we also have the silicone that are anatomically shaped and that can give a more natural shape, and less of the round shape of the traditional implants.    High profile are taller and narrower implants when compared to moderate profile implants of the same volume.The decision is usually based on the patient breast dimensions, amount of breast that the patient can contribute to the projection and I also factor the patients desires. I try my best to also respect the skin quality and elasticity in order to prevent future drooping due to unnecessarily heavy implants.  over or under muscle doesn't dictate what size implant we can use.  The muscle coverage is helpful in very thin patients and seems to reduce capsular contracture according to some scientific studies. Under the breast tissue is the most natural feel and has a less chance of animation deformity when the pectoralis muscle contracts. In most instances only the top implant is covered by muscle and the reset of the implant ends up under the breast tissue.
