This treatment includes an operation to take out the cancer and a margin of normal breast tissue around the cancer. Other terms used for this operation are lumpectomy, wide excision, partial mastectomy, the and segmental mastectomy. In a lumpectomy, only a small amount of breast tissue round the lump is taken. Some surgeons prefer to take a segment of the breast because they feel there is more chance of understanding how much spread has occurred and it often produces a neater result. The surgeon may take up to 1/3 of the breast. Usually, most of the breast will not be affected by the operation.

You will have a general anesthetic and will be in hospital for between 1 and 5 days depending on your progress, the extent of the surgery and whether you are in a private or public hospital.

Breast conserving treatment usually also involves radiation therapy, usually after surgery. Radiation therapy uses x-rays to kill any cancer cells that may be in the remaining part of the breast after the operation.

Key points

  • Breast conserving treatment is as effective as a mastectomy in treating early breast cancer.
  • The surgeon you choose is important to how good or otherwise the results will look.
  • You may want to consider the sentinel node test to limit the impact on your lymph nodes.
  • You should understand lymphoedema before deciding whether to do this.
  • If when cancer is found at the margins of your excision, you may be required to have a mastectomy to remove all the cancer.
  • You should ask to look at photographs of the results of an operation similar to yours
  • Breasts conserving treatment will give the best result when the tumour is on the outside of the breast and not too close to the nipple.
