Breast surgeons usually aim to do an operation that means you can keep your breast (breast-conserving surgery). But sometimes they may recommend a mastectomy. This may be when:
- the lump is large compared to the rest of your breast
- there is cancer in different parts of the breast (called multifocal breast cancer)
- there is widespread DCIS in the breast
- you have had radiotherapy to the chest before to treat another cancer, such as a previous breast cancer or Hodgkin lymphoma
- you have a family history of breast or ovarian cancer.
If you are having a mastectomy, your surgeon will usually ask if you want a new breast shape made at the same time. This is called immediate breast reconstruction.
You can choose to delay breast reconstruction until after you have finished radiotherapy or chemotherapy. Women may also decide to have reconstruction years after their treatment finishes.
You may decide that you do not want to have breast reconstruction. It is important to do what is right for you. You can discuss it with your surgeon and breast care nurse.
Breast reconstruction may not be suitable for some women. This may be because of other medical conditions. These conditions might increase their risk of complications during and after surgery.
If you think you might want breast reconstruction in the future, talk to your surgeon about this before you have a mastectomy. You do not have to make a definite decision at this point, but it will help the surgeon to plan your mastectomy.
You may be able to talk to a surgeon who specialises in breast cancer and plastic surgery before your operation. They can talk you through your options for reconstruction.
