I had a 550cc mentor round high profile silicon implant I had to have a large implant as that is how they fill the old skin, if you do not want to go back to having a larger chest then you have to go. For the lift, the implant is a kind of gel inside so even if they rupture nothing actually leakes out. So have me a bit of peace of mind, also the surgeon did warm me as the skin had already been stretched and had sagged they may not last as long as someone that started off with small boobies that just had then increased again I thought this was worth the risk
