Thank you for your question its hard to answer your question without pictures or an evaluation. I my experience the more fat transferred the better results. Areas to consider would be your abdomen, back bra rolls and flanks at times Inner Thighs and Knees. This would be based on your current projection and how much fat you have to give. Removing the fat from the back bra rolls and waist alone can greatly improve your overall shape and enhance your curves. Once your waistline is more defined like an hourglass you will be able to see your buttock shape. Then once the fat is transferred to the buttock you will get more projection. It's best to consult with a Board Certified Plastic Surgeon to get an examination to assess the areas and outcome. Best of luck.
By and large, there is no 'perfect type' of breast implant. What looked stunning on one of your best friends doesn't necessarily mean that the same implant will be the best choice for you. This is why we recommend face-to-face consultations; an honest discussion with an experienced, knowledgeable plastic surgeon about your desired enhancement is a must. And you'll want to consider your surgeon's opinion and recommendations based on your existing body type and physical assessment.
The breast implant has no clinical bearing upon lumpectomy breast-conservation surgery for women who developed breast cancer after the implantation procedure, nor does the breast implant interfere with external beam radiation treatments (XRT); moreover, the post-treatment incidence of breast-tissue fibrosis is common, and thus a consequent increased rate of capsular contracture. The study Breast Cancer Detection and Survival among Women with Cosmetic Breast Implants: Systematic Review and Meta-analysis of Observational Studies, reported an average later stage in the diagnoses of women who developed breast cancer after undergoing breast augmentation, when compared to breast cancer patients who had not undergone breast augmentation, although this did not ultimately affect the patients prognosis. The use of implants for breast reconstruction after breast cancer mastectomy appears to have no negative effect upon the incidence of cancer-related death.
As with any medical/surgical treatment, individual results may vary. Only a surgeon/physician can determine whether reconstruction or augmentation>is an appropriate course of treatment. The following are general adverse events associated with breast implant surgery: Device Rupture, Capsular contracture, Infection, Hematoma/Seroma, Pain, Reoperation, Implant removal, changes in Nipple and Breast Sensation, unsatisfactory results, breast-feeding complications. Other reported conditions are listed in the Product Insert Data Sheet (PIDS). See full list in the PIDS for the product information. These potential adverse events, including contraindications, warnings, and precautions need to be discussed with your doctor prior to surgery.
When compared to the results achieved with a silicone-gel breast implant, the saline implant can yield acceptable results, of increased breast-size, smoother hemisphere-contour, and realistic texture; yet, it is likelier to cause cosmetic problems, such as the rippling and the wrinkling of the breast-envelope skin, accelerated lower breast pole stretch, and technical problems, such as the presence of the implant being noticeable to the eye and to the touch. The occurrence of such cosmetic problems is likelier in the case of the woman with very little breast tissue, and in the case of the woman who requires post-mastectomy breast reconstruction; thus, the silicone-gel implant is the technically superior prosthetic device for breast augmentation, and for breast reconstruction. In the case of the woman with much breast tissue, for whom sub-muscular emplacement is the recommended surgical approach, saline breast implants can produce an aesthetic result much like that afforded by silicone breast implants, albeit with greater implant palpability.
Since the late nineteenth century, breast implants have been used to surgically augment the size (volume), modify the shape (contour), and enhance the feel (tact) of a woman's breasts. In 1895, surgeon Vincenz Czerny effected the earliest breast implant emplacement when he used the patient's autologous adipose tissue, harvested from a benign lumbar lipoma, to repair the asymmetry of the breast from which he had removed a tumor. In 1889, surgeon Robert Gersuny experimented with paraffin injections, with disastrous results.[further explanation needed]
In 1997, the U.S. Department of Health and Human Services (HHS) appointed the Institute of Medicine (IOM) of the U.S. National Academy of Sciences (NAS) to investigate the potential risks of operative and post-operative complications from the emplacement of silicone breast implants. The IOM's review of the safety and efficacy of silicone gel-filled breast implants, reported that the "evidence suggests diseases or conditions, such as connective tissue diseases, cancer, neurological diseases, or other systemic complaints or conditions are no more common in women with breast implants, than in women without implants" subsequent studies and systemic review found no causal link between silicone breast implants and disease.
For the first part, even though you did not post photos, based on your height and weight you would have plenty of fat to be able to take in my opinion. The relative limit on how much can be removed and send you home the same day safely is about 5 liters of liposuction/fat. I think you would easily be able to get to this upper limit based on your height and weight.
The fat transfer procedure is fairly similar for all areas of the body, by taking fat from one area of your body, usually your stomach, buttocks, or thighs, through Liposuction, and then transferring it to a desired area. You will not only gain in one area, but lose in another area that you would like to. While the procedure is basically the same for all, the information below will explain how each area will show improvement.
The FDA has identified that breast implants may be associated with a rare form of cancer called anaplastic large-cell lymphoma, believed to be associated with chronic bacterial inflammation. Similar ALCL phenomena have been seen with other types of medical implants including vascular access ports, orthopedic hip implants, and jaw (TMJ) implants. As of February 1, 2017, the FDA has received a total of 359 medical device reports of breast-implant-associated ALCL (BIALCL), including 9 deaths. Most cases of breast implant-associated ALCL had implants in for many years prior to the condition, and are usually treated successfully by simple removal of the implant and the capsule surrounding the implant without the need for chemotherapy if no evidence of systemic disease exists. If women with implants present with delayed swelling or fluid collection, cytologic studies and test for a marker "CD30" are suggested. The American Society of Plastic Surgery (ASPS) states, "CD30 is the main diagnostic test that must be performed on the seroma fluid as routine pathology or H&E staining can frequently miss the diagnosis."  Diagnosis and treatment of breast implant associated ALCL now follows standardized guidelines established by the National Comprehensive Cancer Network.
