What is the best kind of breast job at 60?

Age is not important: The type of surgery required to enhance your breast depends on you present anatomy. If the nipple is in the proper position but the breast is deflated then you would require more volume with an implant. If the breast is droopy then you may need a lift with or without an implant. If the breast is too large then a reduction may be required. A consultation plastic surgeon is required.

The breast job...: That gives you what you are looking for and can be done well and safely. There is no one pat answer. Talk with your local plastic surgeon.
