Frequently Asked Questions
Is it a side effect if I can feel a lump after breast fat grafting?
Since it may appear temporarily during the recovery process, it is more accurate to confirm it through regular checkups rather than self-diagnosing. However, if you feel a hard lump that does not shrink over time, or if a specific area is particularly hard and bulging, we recommend consulting with your medical team.
How are oil cysts and fat necrosis different?
Fat necrosis is a phenomenon in which fat cells deprived of blood supply die and harden into fibrosis, and it may feel like a hard lump upon palpation. An oil cyst is a condition in which oily substances leak out from necrotic fat cells and remain in the form of a sac; due to its fluidity, it may feel slightly softer.
Does 100% of the transplanted fat survive?
That is not the case. If some of the transplanted fat cells are not sufficiently connected to blood vessels, they will naturally be absorbed or lose their function over time. During this process, if the fat hardens or oily components leak out to form small sacs, it can lead to oil cysts or fat necrosis.
If I experience any symptoms after surgery, is it necessary to check?
This applies when you feel a hard lump that does not shrink over time, when a specific area is unusually hard or bulging, when there is noticeable asymmetry even after the swelling subsides, or when the skin surface appears uneven or looks like an indentation.
If a lump is felt, do I absolutely have to have revision surgery?
That is not the case. It may be felt temporarily during the initial recovery process, and even if it is confirmed to be fat necrosis or an oil cyst, observation alone may be sufficient depending on the size and symptoms. An accurate diagnosis is the priority. Chief Director Shin Dong-jin examines the size, location, and progression of the condition to distinguish between cases where observation is sufficient and those requiring treatment, providing clear guidance accordingly.
Are oil cysts or fat necrosis dangerous to health?
Although most do not lead to immediate health threats, they can cause discomfort or cosmetic issues depending on their size and location, so proper care is required.
Do side effects disappear completely when using SVF?
While SVF helps create an environment where fat settles stably, it does not completely rule out the possibility of all side effects. Achieving stable results requires a precise procedure combined with proper pre- and post-treatment care.
When is the best time to have follow-up observation after surgery?
The general follow-up schedule involves checking for initial swelling and bruising at 1 to 2 weeks, assessing tissue condition via palpation around 1 month, confirming the presence of lumps or cysts using imaging tests such as ultrasound if necessary around 3 months, and checking the final results of engraftment and left-right balance around 6 months. SC301 Clinic provides regular check-up schedules based on these timings and verifies the condition through imaging tests if required.
What conditions are necessary for fat to settle properly?
It is crucial to ensure smooth blood flow, that the fat is injected evenly without clumping in one spot, and that proper pre- and post-operative care is provided. The better these factors are met, the more comfortably the fat settles, and the risk of side effects naturally decreases. SC301 Clinic adopts the fundamental principle of mixing healthy fat and fat-derived cell components in appropriate proportions and injecting them uniformly in very small units.
What should I check during the consultation?
We recommend that you check how fat is uniformly distributed during grafting, whether procedures are in place to handle oil cysts or fat necrosis, the schedule and methods for regular post-operative check-ups, and the policies regarding additional costs or re-operation in the event of side effects. SC301 Clinic provides guidance on these items first during the consultation phase.
