We suggest that you change your breast implants, since if you feel masses, it is quite possible that implants have undergone wear and tear rupture and inflammatory masses are there or there is folding or shrinkage of implants. After 20 years, you should change them anyway. You can have the breast lift along-with implants. We do Scar-less Breast Lift. You can avoid the long unaesthetic scars of breast lift which take place with conventional techniques.
