Breast hematoma is a collection of blood within the breast. It arises from internal bleeding (hemorrhage) and may arise due to trauma (breast injury or surgery) or due to a non-traumatic cause.

Symptoms may include visible discoloring (ecchymosis), breast pain, and swelling.

The symptoms may be similar to those of fibrocystic breast changes.

A breast hematoma may appear due to direct trauma to the breast, for example from a sports injury or a road accident, for example a vehicle collision in which a seat belt injury occurs.

Hematoma can also be a consequence of breast surgery, usually due to post-operative bleeding. Bleeding may occur shortly after the intervention or a number of days later and can occur for cosmetic surgery (for example breast reduction or breast enhancement) and for non-cosmetic surgery (for example lymph node removal, lumpectomy, or mastectomy). More rarely, hematoma can result from breast biopsy.

Rarely, a breast hematoma can also occur spontaneously due to a rupture of blood vessels in the breast, especially in persons with coagulopathy or after long-term use of blood-thinning drugs such as aspirin or ibuprofen.

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, A recent hematoma is usually visible in a mammogram. and it also shows typical signal intensities on MR imaging. If a differentiation from breast cancer is necessary, a hematoma biopsy may be indicated.
