Re: Seratoma

Hi Betty1boob

Thanks for your post. It sounds as if you’re having a difficult time with your seroma.

As you’re still feeling tender and uncomfortable, do go back to talk to your treatment team again. As Delly says, the fluid eventually reabsorbs. However, the team may be able to assess you to see if they can drain the fluid again.

If you experience redness or have a raised temperature, it could be a sign of infection. Also, if the swelling worsens, this can indicate a swelling called lymphoedema. Again, do contact the breast care nurse or GP if you develop either of these symptoms.

Taking regular pain relief with an anti-inflammatory might help reduce the swelling and discomfort. Maintaining your post operative exercises will encourage the fluid to mobilise.

At Breast Cancer Now, we offer a range of free supportive services that you might be interested in. For more details about all of these services, please see the information on the link, or call our free Helpline.

Re: Seratoma

Hi Betty1boob

You haven't told us what procedure you've had, but I'm presuming a mastectomy from your name??!

I too developed a seroma after my 1st mastectomy and full node clearance. Like you, I contacted the team, and arranged to go back to the ward to have it drained (aspirated) by a hypodermic needle >> was great for a few days. But it started reforming again within a week. So arranged to go back for the same, two weeks later, and it was then fine. Any following "slight" build of fluid was then naturally and gradually absorbed by my body. So I would get back in touch with your BCN/team. It may just need another draining, and then be okay. Try it again, lovey. 

If it's the same original size, prior to your 1st draining, I doubt any of the other things you're trying will make much or any difference to it.

Hope a 2nd time sorts it for you.  Let us know.

All good wishes to you,  Delly xXx



Hi I feel like I have a bean bag under my arm (seratoma) went to have it drained it didn’t work I can’t seem to find many options of what to do. So far heat (hot water bottle) compression ( tried a sports bra today) have ordered post op crop top with sleeves as my arm also feels tender and obviously pain relief the BCN didn’t have any suggestions apart from keep it moving and pain relief. Thank you
