Do you have a blood clot in your breast? Let's learn about Breast Hematoma!

Have you ever noticed a small lump, a lump, or a bruise that looks blue on your breast? It's normal to feel a little scared when you see something like that, right? But most of the time, this is a small collection of blood inside your breast, which is a blood clot (hematoma). It's like a bruise when we fall somewhere. So today, let's talk about this blood clot (Breast Hematoma) in a simple way that you can understand.

Let's first see what a breast hematoma is.

Simply put, a breast hematoma (pronounced "hee-ma-to-ma") is a collection of blood inside your breast. It's like a bruise. It happens when the breast is injured or traumatized in some way. This collection of blood can be superficial, just under the skin, or deeper within the breast tissue.

Imagine, when you hit your hand somewhere, it turns blue, right? That's what happens inside the breast. When a small blood vessel is damaged, some blood collects in the surrounding tissue.

But the best thing is, most of the time, these types of blood clots get better on their own over time, without any treatment.

Who is most likely to develop this condition?

A hematoma in a breast can occur in any person's breast if there is an injury or damage. This injury can occur in a variety of ways.

For example:

  • Because of a fall somewhere.
  • Because the seat belt is pressed against the chest while riding in a car.
  • Because of an accident while playing.
  • Or it could be due to a medical examination (`breast procedure`) performed on the breast.

Another thing is that people who take blood thinners , such as aspirin or other anticoagulation medications, are more likely to develop blood clots. Because these medications make the blood less likely to clot, even a small wound can cause a little more bleeding.

Is this a serious situation? Should I be afraid?

Most of the time, a hematoma in the breast is not serious and will heal on its own. However, if you think you have one, it is important to let your doctor know.

Remember, especially if you feel like a blood clot is growing very quickly, you should seek medical attention immediately. In such cases, don't delay.

What are the symptoms of this? How do you recognize it?

A superficial hematoma is easily visible, just under the skin. It looks like a bruise. However, a deep hematoma may not show any signs of bruising for several days.

If you have breast surgery, you may start to notice signs of a blood clot, usually within 24 to 72 hours. Sometimes, blood clots can form even if you have drains placed after surgery.

The main symptoms are these:

  • A change in color like a bruise: It's like when we fall and our limbs turn blue. It's dark purple/red at first, then turns green, gray, and then yellow after a while and then disappears.
  • Breast pain and/or tenderness.
  • A knot that catches in the hand: This knot may be soft like a sponge, or it may be a little firm.
  • Breast swelling.

Does a blood clot (hematoma) in the breast cause pain?

Yes, sometimes these blood clots can cause pain. However, some people can develop them without any symptoms or pain (`asymptomatic`).

If you have a breast injury and you go for a mammogram a few days later, you may see this blood clot. Therefore, before you have a mammogram, it is very important to inform the mammogram technician if you have had a recent breast injury.

Why do blood clots (hematomas) form in the breasts? What are the causes?

The main cause of hematomas in the breast is some kind of damage to the breast tissue, such as an injury or a medical procedure.

For example:

  • Another accident while playing.
  • A pull somewhere.
  • A car seatbelt is tightened.

These are the most common reasons.

Due to breast tests and surgeries

Some breast procedures can also cause blood clots, but the risk is much lower. If you have any of these tests or surgeries, your doctor will inform you about the risk of blood clots after the procedure.

Here are some examples:

  • Minimally invasive breast biopsies are tests that take a small piece of tissue from the breast.
  • Breast cancer surgeries.
  • Cosmetic plastic breast procedures, for example, breast reduction surgery.

Are there risks for people taking blood thinners?

Yes, blood clots can form spontaneously for no apparent reason, especially if you have a bleeding disorder or if you are taking blood thinners.

Some of the most commonly used blood thinners are:

  • `Warfarin (Coumadin®)`
  • `Apixaban (Eliquis®)`
  • `Rivaroxaban (Xarelto®)`

Very rarely, a blood clot like this can also be a symptom of breast cancer. But keep in mind that this is a very rare occurrence .

How do doctors confirm that this is a breast hematoma?

Most of the time, a doctor can diagnose a hematoma in the breast by doing a breast exam (clinical diagnosis). It doesn't require any major tests. However, imaging tests are sometimes used to see how far the hematoma has spread and if it's getting bigger. Or, if the diagnosis is unclear, that is, if there is doubt about whether it's a blood clot or something else, imaging tests may be done.

Mammogram test

If you have a large hematoma, it can look like cancer on a mammogram. Especially if there is scar tissue nearby. Scar tissue looks like cancer cells on a mammogram. However, hematomas are not cancer, they are benign.

Ultrasound examination

Your doctor can do an ultrasound to see if the lump is solid or fluid-filled. An ultrasound can also look for small fluid-filled sacs (called seromas) inside the breast. These seromas can often occur together with hematomas.

Will a biopsy be necessary?

Very rarely, if there is a question about whether a lump seen on a mammogram or ultrasound is a blood clot (hematoma) or cancer, your doctor may take a small tissue sample (biopsy) from the area and send it to a laboratory for testing.

Every time you have a mammogram, it is important to tell your doctor if you have had a previous hematoma in your breast. This is because the scar tissue from that breast injury can look like cancer on a mammogram. So it is important for your doctors to know your medical history when you are being tested for breast cancer.

Is there a treatment for this? What should I do?

Most breast hematomas do not require any special treatment. They can simply be monitored, as they will heal on their own over time.

However, if a blood clot is getting bigger, you should have it checked out by your doctor. In that case, see your doctor, or go to the nearest emergency room (ER) if the doctor's office is closed.

Things you can do at home to get relief

You can usually manage the swelling and pain caused by a hematoma in your breast at home.

  • Apply cold therapy for the first 48 hours. Applying cold to a newly formed blood clot can help reduce pain, inflammation, and swelling. Wrap some ice cubes in a towel or apply a cold compress to the area for 20-30 minutes three times a day.
  • Take a medicine like `Acetaminophen (Tylenol®)` for pain. Do not take `Nonsteroidal anti-inflammatory drugs (NSAIDs)` (e.g., Ibuprofen, Diclofenac)`, as they also have blood-thinning properties and can increase bleeding.

How long does it take for a blood clot (hematoma) to heal?

It usually takes about four to six weeks for a blood clot (hematoma) to completely disappear. However, in some cases, it can take several months. Very rarely, it can take years for the marks to completely disappear.

See a doctor to see how your blood clot is healing. It may require treatment.

Are there times when surgery is necessary?

If the hematoma is very large, growing very quickly (or if it seems like your breast is getting bigger) and your doctor suspects it is bleeding, then they may need to take you to the operating room to remove the clot and stop the bleeding.

Once a blood clot forms and becomes `stable`, it can stay the same size for about a week or two – and then it starts to shrink in size.

Is there no way to prevent the formation of breast blood clots (Hematomas) like this?

It is usually difficult to prevent breast hematomas. However, if you are taking blood thinners, you are more likely to develop a blood clot if you injure your breast. So if you are taking such medications, follow your doctor's instructions on how to avoid injuring your breast.

If I find out I have a breast hematoma, what can I expect going forward?

Most likely, your body will absorb the blood in your hematoma over time, meaning it will heal on its own.

What are the signs that require immediate medical attention? (When should I see a doctor?)

If you have had a breast procedure, your doctor will check for a hematoma during your follow-up.

But if you see any of these signs of infection, see a doctor immediately:

  • If your breast becomes increasingly red, swollen, or painful.
  • If a clear fluid (such as pus) is oozing from the surgical wound (incision).
  • If you feel a warm sensation when you touch your breast.
  • If you have a fever.

If you see a sign like this, don't delay, see a doctor immediately.

So, here are the take-home messages you need to remember from what we've talked about:

Finding out that you have a blood clot (breast hematoma) in your breast, especially if you have had an injury or are recovering from breast surgery, can be a bit disconcerting. That's normal.

But the good news is, just like a normal bruise, this blood clot is just a sign of damaged blood vessels. And, like a normal bruise, it will likely heal on its own over time. Your body is very good at making these small repairs.

But if it's taking a long time for you to recover, or if you have any concerns or doubts about this, see a doctor and talk about it. Then they can decide whether or not it needs any intervention.

So, don't be afraid. Talk to the doctor and explain everything. Then you will feel relieved too.
