Breast size going up 18 months after lumpectomy


Re: Breast size going up 18 months after lumpectomy

Hi Marydoll

Thanks for your post in the Ask Our Nurses area of the forum.

Both breast size, volume and shape can alter following surgery for breast cancer.  This may be due to the healing process or as the tissue settles down or repositions in the months and years following surgery. The breast will not regain the mass lost at surgery but occasionally this can  be due to conditions such as lymphoedema of the breast. Some people may also find the size and volume of their breast alters due to weight change, for example weight gain may lead to an increase in breast size.

However, we’d encourage anyone with a new and persistent change following treatment for breast cancer, to report this to their GP or treatment team so this can be checked out.

Do call our Helpline if you would like to talk this through or have any further questions. Your call will be confidential, and the number is free from UK landlines and all mobile networks.

The number is 0808 800 6000 (Text relay prefix 18001).

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

Breast size going up 18 months after lumpectomy

Quick question following a concern. Is it normal for the breast operated on (lumpectomy, about 80 grams of tissue removed) to regain the lost mass and look the same size (not shape) as the other breast again (previously, no assymetry)? I can't find any information about this. It might be useful for all of us to hear what other people have experienced. Because, if it is normal, that's reassuring. If it isn't, is it something to worry about?
