Hi Katie, you’ve got the right idea. Implants come in different ‘profiles’ (which your surgeon will advise you on). For example, a higher profile implant means it has a smaller diameter to sit across your chest, suiting a narrow body frames, lower profiles mean a bigger diameter across the chest for wider body frames.
With higher profile implants you can increase more cup sizes with less cc as you don’t need as much for them to project out or “look big”, this is because the diameter is smaller and therefore needs less cc to increase cup sizes. With lower profile implants you’ll need more cc to look bigger. Medium profile implants are called ‘moderate’. Also, if you have lots of breast tissue then you’ll need higher cc to reach a higher cup size than you already have.
Also don’t forget, implants can be placed under the muscle (‘partials’- meaning most of the muscle covers the implant, ‘submuscular’ and ‘partially submuscular’ – these all mean the same thing but different surgeons use different names) or over the muscle (subglandular) also impacting the size.
Im so sorry if this doesn’t make sense, I tried my best to explain it!x
