[3] Small breast hematomas often resolve on their own within several days or weeks by means of reabsorption of the blood.
Post-surgical breast hematomas can also impede wound healing and therefore impact the cosmetic outcome.
[4] There is preliminary evidence that, after breast implant surgery, the presence of hematoma increases the risk of developing capsular contracture.
[1] When there is post-operative swelling after breast surgery or core needle biopsy, a breast ultrasound examination may be indicated in order to differentiate between a hematoma and other possible post-surgical complications such as abscess or seroma,[7] A recent hematoma is usually visible in a mammogram.
[9] A recent hematoma can be drained by means of needle aspiration or (rarely) open surgical drainage.
