The simple answer to the risk of losing sensation in the breast and nipple is that your chances of this are very low, somewhere between 1-2%. The incision is made in an area that doesn’t have any sensory nerves as a precautionary measure to minimize any potential risk to loss of sensation. Furthermore, the breast tissue itself is not cut. It is moved aside so that a space can be created for the implant, and then the implant is placed in the newly created opening. There have been some cases where sensation has been increased with the nipple and areola due to the implant pushing them forward.
A breast reduction with lift surgery combines two procedures to improve the size and shape of the breasts. A reduction involves decreasing the size of overly large breasts by removing excess tissue and skin. A breast lift is done in order to raise and reshape the breasts. The breast reduction and lift procedure helps to alleviate problems caused by overly large, sagging breasts, including:
Saline-filled Breast Implants. Saline-filled breast implants are filled with sterile saline (salt water). They come in both smooth and textured shells and can be round or anatomically (tear-drop) shaped. Saline breast implants are also available in low and high profiles, and in many sizes. A saline-filled breast implant is usually empty before implantation. The doctor moves it into place during your surgery, and then fills it. The saline is administered via a process that ensures the implants remain sterile.
A lot of patients are concerned over whether or not breast implants are safe. The answer to this is yes. To date there has never been a single study performed anywhere in the world that says that breast implants are dangerous or increase your risk of either breast cancer or any other systemic diseases. Furthermore, the new implants whether saline or silicone are manufactured much better than they used to be 10 or 15 years ago which not only makes them safer but has extended their lifetime use. Even the silicone envelope that encompasses the material inside, whether saline or silicone, is much more durable than in the past. If you do chose to go with silicone implants, even in the case of a rupture, the silicone does not leak to a distant site or go into your bloodstream.
When a silicone breast implant ruptures it usually does not deflate, yet the filler gel does leak from it, which can migrate to the implant pocket; therefore, an intracapsular rupture (in-capsule leak) can become an extracapsular rupture (out-of-capsule leak), and each occurrence is resolved by explantation. Although the leaked silicone filler-gel can migrate from the chest tissues to elsewhere in the woman's body, most clinical complications are limited to the breast and armpit areas, usually manifested as granulomas (inflammatory nodules) and axillary lymphadenopathy (enlarged lymph glands in the armpit area).[41][42][43]

They are essentially very similar procedures. The difference is in the amount of breast tissue removed. In a breast lift procedure, the nipple areolar complex is lift to a better position on the breast, and some breast tissue is removed and the breast envelope tightened. In a breast reduction, the nipple areolar complex is also lifted, but much more breast tissue is removed. 
The last thing and the most important decision you will have to make is selecting the right plastic surgeon to perform your breast augmentation surgery. It is critical that you choose somebody who not only has the experience in these types of surgical procedures but maybe more importantly, the credentials. Here in the United States, the best thing you can do is look for a board-certified plastic surgeon who is not only experienced and credentialed but also has the qualities and qualifications that make you feel confident in their abilities.
In some very rare cases, usually about 2 to 3 percent your immune system is not satisfied with simply forming a capsule, and the inflammation continues to the point where the capsule thickens and sometimes squeezes the implant and distorts it. This can sometimes be painful, and in those cases, it usually requires surgical intervention to either release the capsule or to possibly remove the implant.
This average total, according to the 2016 statistics from the American Society of Plastic Surgeons, is based on the surgeon’s fee only and does not include the cost of anesthesia, facilities, and materials (stitches, bandages, drapes, etc.). The price will also depend on doctor, patient, and region. The cost of reduction, though, varies greatly patient to patient. A reduction procedure could take three to four times longer than an augmentation, and the cost would reflect that.
Most experts agree that Botox can also be a preventative measure for some younger clients, ‘It preserves the skin and stops lines developing,’ explains Spyrou. ‘Botox softens and temporarily freezes the muscles, which means the treated area will stay flat. If you can’t physically frown, then over time, the line will smooth out.’ That being said, there's a lack information about the long term effects of starting botox at a younger age. "The long term safety data in these treatments is usually focussed on older individuals." Says Dr. Justine Hextall, Consultant Dermatologist on behalf of The Harley Medical Group. So as with most cosmetic procedures, there are risks.
The study Safety and Effectiveness of Mentor’s MemoryGel Implants at 6 Years (2009), which was a branch study of the U.S. FDA's core clinical trials for primary breast augmentation surgery patients, reported low device-rupture rates of 1.1 per cent at 6-years post-implantation.[49] The first series of MRI evaluations of the silicone breast implants with thick filler-gel reported a device-rupture rate of 1 percent, or less, at the median 6-year device-age.[50] Statistically, the manual examination (palpation) of the woman is inadequate for accurately evaluating if a breast implant has ruptured. The study, The Diagnosis of Silicone Breast implant Rupture: Clinical Findings Compared with Findings at Magnetic Resonance Imaging (2005), reported that, in asymptomatic patients, only 30 per cent of the ruptured breast implants are accurately palpated and detected by an experienced plastic surgeon, whereas MRI examinations accurately detected 86 per cent of breast implant ruptures.[51] Therefore, the U.S. FDA recommended scheduled MRI examinations, as silent-rupture screenings, beginning at the 3-year-mark post-implantation, and then every two years, thereafter.[22] Nonetheless, beyond the U.S., the medical establishments of other nations have not endorsed routine MRI screening, and, in its stead, proposed that such a radiologic examination be reserved for two purposes: (i) for the woman with a suspected breast implant rupture; and (ii) for the confirmation of mammographic and ultrasonic studies that indicate the presence of a ruptured breast implant.[52]
