Breast swelling


Re: Breast swelling

Dear Livelifetothefull


Thanks for your post.


Swelling can happen for different reasons. For example, swelling can happen after radiotherapy and settles within a few weeks following treatment. 


Lymphoedema can also develop after treatment. Symptoms include swelling in the arm, hand, fingers, breast or chest wall on the side of the body where you had your surgery or radiotherapy. The earlier lymphoedema is assessed the better so as Jaybro says let your breast care nurse, hospital treatment team (or GP) know about this.  You can also call our free, confidential Helpline if you would like to talk this through or have any further questions. The number is 0808 800 6000.


Our opening hours are Monday to Friday 9am - 4pm and 9am -1pm on Saturday. Out of hours you can leave a message and we will call you back when we next open. 


Best wishes

Re: Breast swelling

Hi there


I had radiotherapy in May-June and thought it was a doddle. I’d had a full mastectomy and full axillary clearance in October and then chemo. Then 3-4 weeks after finishing radiotherapy, I started getting searing pain in what’s left of my breast muscle and was told this is a normal response to radiotherapy (where an immediate side effect is anything within 6 months!!). It’s still painful, with slight swelling, and is beginning to itch inside. Not anything scratchable. I’m currently trying to ring the radiotherapy breast nurses to check. If I were you, I’d ring the hospital because they know your specific case, just to be on the safe side, but it sounds about ‘normal’ to me. Alternatively you might ring the nurses here - they are very helpful.


Good luck x


Breast swelling


I has wide local excision & sentinel node removal in March, followed by Radiotherapy in May/June.  Over the last few weeks my affected breast has started to swell, it is now noticeably larger than the other, it’s not hot. 

Do I need to worry that it’s started to swell 5 months post-op ?
