Recurrence means either that DCIS has appeared again, or that an invasive cancer has been found in the treated breast. Recurrence of DCIS is never in itself life-threatening with careful follow-up and treatment. Even invasive cancers that are detected early are not life-threatening. Recurrence does mean that you have to deal with treatment again. The use of radiotherapy after lumpectomy significantly decreases the rate of recurrence.

The risk for breast cancer recurrence after breast-conserving treatment is approximately 8%. If recurrence occurs, the chance of the cancer being invasive is approximately 50%. Mastectomy is associated with a 1% risk for chest wall recurrence. Most patients with recurrent disease can be treated effectively.

Prophylactic mastectomy
Women who are in a high-risk category due to a strong personal or family history of breast or other cancers may choose prophylactic, or preventive mastectomy. A prophylactic mastectomy removes one or both breasts — even if they are not known to contain cancerous cells — to reduce the risk of cancer. This option should be carefully discussed with your doctor. If you choose prophylactic mastectomy, reconstructive surgery can be done at the same time or at a later date. If you are considering this surgical procedure, you may want to discuss your family's history of cancer with a genetic counselor to get a better understanding of your personal risk for developing the disease.
