What if Breast Hematoma Goes Untreated?

Thank you for your question. A hematoma can be very mild or very pronounced in its presentation. A mild one may induce slightly more swelling and increased bruising and will likely resolve on its own. A more severe hematoma can result in dramatic asymmetry in terms of swelling, feelings of light headedness due to loss of blood, severe bruising, and can be rapidly growing. If you every experience the latter, then I would contact your surgeon immediately and if you have trouble, you may even go to the ER. Larger hematomas often have to be surgically drained.  I would follow-up closely with your plastic surgeon.

Bleeding is a complication that can happen from any surgery.  In breast augmentation, if a hematoma (collection blood and clot around the implant) occurs, it is better to surgically have the hematoma removed within 2-3 days to avoid risk of capsular contracture (hardening of the implant capsule).  If significant time has elapsed from the surgery and hematoma, then, it is wiser to wait until all inflammation calms down before another surgery is done.  A hematoma can get infected if left alone and so you have to look out for redness, pain, fever, etc.  If an infection sets in, then, the implant has to be removed and the implant pocket needs to be cleaned out and the area has to be allowed to heal for 6 months to a year before attempting to put the implant back in.

After 6 weeks have already passed, there is no reason to go back into the breast pocket to evacuate the hematoma unless there is any sign of infection or a capsule has formed.  The discoloration will likely resolve altogether with time.

Untreated hematomas (collection of blood in pocket) after breast augmentation can lead to long term problems. Early treatment likely reduces these risks.


Capsular contracture: the blood causes inflammation which can lead your body to produce a thicker capsule. This can happen in the short or long term.

Infection: old blood is perfect food for bacteria. As long as it is in there, the risk of infection is higher.


The best course of action for you depends on your individual circumstances. Old blood may need to be drained. If you truly have significant capsular contracture, a revision may be necessary to improve this. This is often performed after tissues have softened. 

Not treating the hematoma could lead to a poor result and higher chance of infection. It is critical that you see a board certified plastic surgeon to determine a plan that is most likely to get you to a good result safely.

Best wishes,

At six weeks after having a hematoma, there is no compelling reason to re-enter the breast implant capsule. This was an issue to consider at the time the diagnosis was made, but that time has passed. It will likely be necessary in the future to perform a capsulectomy, but that awaits further healing and how the breast looks and feels with more time. Infection is always a risk and just because it has not occurred yet does not mean it will not occur. But that in and of itself is not a reason for surgery now.
