The size of your breasts is determined by your genes. Exercises, hormones or other medications will have no effect on the size of your breasts. Some girls are so unhappy about the size they decide on an enlargement.
To enlarge the breasts implants are used.
The surgeon makes incision in the armpits, in the crease under the breasts or around the nipple to insert the implants.
When inserted, the implant can be filled with silicone-gel, soy oil or salt water.
An operation in the Netherlands costs about €4000,-
