Symptoms
Bruisesare generally flat and can turn the skin a dark purple color.
As they fade over time, they can change to a yellow, green, or light brown color.
The pooled blood may cause inflammation and swelling.

The skin above a hematoma can appear to be bruised and, in the case of surgery, broken.
When feeling a hematoma, it may feel like a firm lump beneath the skin.
That can be frightening if you’re familiar with the commonsymptoms of breast cancer.
Causes
A breast bruise or hematoma can happen to anyone regardless of age or menopausal status.
Hematomas are generally brought on by more serious trauma.
They can also be resulting from a weak blood vessel breaking in response to a bump or jolt.
Surgery
Any key in of surgery on the breast can damage blood vessels and cause a bleed.
Certain types of breast biopsies can cause a hematoma.
Breastfeeding
People who are breastfeeding may also experience bruising on the breast or nipple.
This fast-growing cancer can cause the affected breast to become swollen, red, and tender.
The skin may also appear pink or reddish purple.
Diagnosis
Bruising can be diagnosed on a physical exam, simply based on its appearance.
Larger hematomas are usually visible on amammogramand can sometimes look suspicious on other imaging as well.
In some cases, a biopsy may be needed to diagnose a hematoma.
Mammogram
A small hematoma probably wont be seen on amammogram.
If it resolves on its own, it wont appear on your next mammogram.
Spots on mammograms that are more suspicious for cancer appear with a spiky outline.
Hematomas may have some suspicious-appearing features due to scarring or how the hematoma affected the breast tissue.
In some cases, a biopsy may be performed if the imaging continues to look suspicious.
Treatment
For mild bruises or hematomas, no specific treatment may be needed.
The body will absorb the blood, and they will eventually go away on their own.
However, there are things you might do to help speed the healing process along.
This can help the blood reabsorb.
NSAIDs thin the blood, which can make your condition worse.
When to Call a Healthcare Provider
Most mild bruises and hematomas resolve spontaneously.
However, larger or deeper hematomas can be problematic and may require medical attention.
Although these can occur without an injury, most are due to an injury or surgical procedure.
A hematoma is not cancer, and many times no specific treatment is needed.
Mild bruises and hematomas generally heal on their own in time.
