Is Seroma Formation (fluid in breast) After

Breast Cancer Surgery Normal?

This is the question we often encounter while consulting with patients who have undergone Mastectomy.

In fact, this is the most common question that almost every breast cancer patient has. So today, in this blog, we will address this question in detail.

Why Does Seroma Formation Occur?

After every surgery, irrespective of the reason and cause, seroma formation is a normal response of the body. That’s the reason why surgeons place a filter to ensure the seroma does not come out.

Especially in the case of breast surgery, seroma formation is common as the surface of the breast is quite large.

Moreover, during the breast surgery, we also remove the lymph nodes from the armpit along with some lymphatics. So the fluid from the open lymphatic channels oozes from there too.

In short, seroma formation after the surgery is not an abnormality. It’s absolutely normal, and you will have to be prepared for it before the surgery.

As your surgeon is aware of this, they place a drain at the site of the operation. We have observed that fluid formation is more in patients who are overweight, have high blood pressure or are diabetic.

The fluid oozes for a longer time, and after the operation, the risk of swelling is more in such patients.

So the best steps you can take to minimize fluid formation are to reduce your weight, manage your diabetes efficiently and not stress yourself too much.

Apart from that, you have to take proper care of your drain.

Here are a few mandatory steps you have to take:

  1.  Ensure the drain is not blocked
  2.  Empty the drain at least once a day
  3.  Measure and note the fluid
  4.  Make sure there are no clots in the drain

    In some studies, it’s been indicated that if the compression dressing is used, it might end the formation of the seroma quickly. But this is not a 100% proven theory.

    So we do not recommend our patients compression dressings. Instead, we recommend our patients wear a padded bra that keeps some pressure on the breast to reduce the dead space where the seroma is accumulated.

    Remember, this is not a 100% solution to the issue, but it can be helpful up to a certain extent.

    In short, there is nothing to worry about if you are experiencing seroma formation after the surgery.


    If it’s causing you pain or discomfort, you can consult your doctor. He/she will clean the area of the surgery and will remove the seroma with the help of a fine needle.

    The seroma formation reduces in two to three months. There are extremely rare cases where the seroma continues for up to 6 months.
