Fat grafting is a valuable tool in breast surgery. This technique has gained more popularity over the past 7 years. There are many techniques used to harvest the fat, process the fat and then re-inject the fat. Conventional suction lipectomy is performed with a small diameter cannula, processed by separating the liquid and fibrous tissue from the fat, and then placed into syringes for re-injection or through a closed system.

Fat grafting side effects

fat grafting carries potential risks and complications including lumpiness, rippling, fat atrophy or loss, and asymmetry. In areas of the body where the fat is grafted more superficially such as the lower eyelid skin, these complications can be more noticeable.

Side effects of fat grafting

Like any surgical procedure, fat transfer has potential complications. The most predictable "'side effect" of fat transfer is that not all of the cells survive and thus some of the volume is lost. This usually stabilizes around 3-6 months. One of the most important "side effects" of using fat is that it changes with your body, meaning if you gain or lose weight your breasts will change size accordingly.  It is possible to have small hard lumps where a cluster of cells dies. These are usually not visible, but can be felt. The addition of fat cells to the breast can cause calcifications seen on mammograms, which may increase the chance of needing a biopsy. 

Fat based augmentation is a relatively new technique. As it becomes more popular and time goes on we may learn of other complications and side effects.

Side effects of fat injections to breasts is a delicate subject

Fat grafting emerged in the last few years as a very useful tool in facial rejuvenation, augmentation of different body areas and even wound healing by stem cell transfer. When it comes to the breast, it is a completely different issue. The breast is a hormone sensitive organ and this is related to breast cancer. Now, to make things clear,the scientific evidence so far did not prove a relationship between cancer and fat grafting but there is a lot we do not know.

The current issue with fat grafting to the breast is the fear of having fat necrosis, lumps and biposies and more surgeries. Hope that helps!

Fat transfer side effects

Swelling and bruising are common side effects that are considered temporary. Some of the fat may not take to the area, either, so you may need a few sessions to achieve your desired size. 

Some more serious risks include calcification of fat, oil cysts and scarring. These may be mistaken for cancer on mammograms. However, I have not found this to be a concern for my patients, and the procedure has been able to achieve great results! 

Side effects of fat transfer

With any surgical procedure, risks and complications exist.  Fat transfer is a safe and effective way to increase your breast size from 1/2 to 1 cup on average.  The usual risks from surgery like bleeding, bruising, swelling, infection, and numbness are low, and scarring is very minimal.  However, there are some risks unique to fat transferring like fat necrosis, where the transfer piece of fat dies and forms a hard ball. There can be shrinkage, loss of fat, formation of fat oil drops, and lumps. I do suggest finding a board certified plastic surgeon who has done several fat transfers to the breasts, and discuss all your concerns.  Sometimes there will also be changes on your mammagrams from fat transfer that shows some abnormalities. For most women, this is a very safe alternative to breast augmentation, with no risks of implant problems.

Fat transfer to breast side effects

Fat grafting to the breast is becoming very popular.  It can offer a nice enhancement with minimal scars and the added benefit of treating another area with liposuction.   As with all surgeries the vast majority of the time you will have some discomfort but no real problems.  However, make sure that you are seeing a qualified plastic surgeon for this and that they do it as a regular part of their practice.  There are several things that they should discuss with you; too many to list.  Some of the key areas of your discussion should include the cosmetic concerns including under/over correction and dimpling.  That the percentage of fat that survives is variable and a second procedure may be required.  Of the fat that does not survive most is resorbed by your body but some may result in calcification which can influence mammogram interpretation.  And finally a discussion about the role of stem cell activation with fat transfer.

With any surgery, including fat transfer for breast augmentation, there are potential risks and/or side effects.  These can include: infection, bleeding, fat resorption, and fat necrosis.  Check with a board certified plastic surgeon who has extensive experience in both fat transfer and breast augmentation with breast implants to see which option may be in your best interest.

Fat transfer to the breasts

Compared to the face fat transfer to the breast has the same risks of even resorption of the fat with potential unevenness, etc.  My only negative comment about fat trasfer to the breasts is that don't expect major changes.  Increase of cup size of one or more is infrequent.  Enhancement and improvement of some areas of the breast is more likely.

Fat Transfer- possible Side Effects

Sometimes, the fat harvested does not fully incorporate into the breast(s) and can be of less volume than originally anticipated. In this case, you may need to repeat this procedure if there is fat available for staging. Also, if the fat does not fully incorporate, it can sometimes form firm nodules due to fat necrosis which can mimic cancer on mammogram. This may require MRI and/or biopsies to rule out malignancy if the nodule does not resolve completely. Fat transferring may also affect a woman's ability to breast feed in the future, but does not eliminate the possibility.
