Treatment options by Stage
Ductal Carcinoma In Situ (DCIS)
Treatment of ductal carcinoma in situ (DCIS) may include the following:
- Breast-conserving surgery and radiation therapy with or without tamoxifen.
- Total mastectomy with or without tamoxifen.
- Breast-conserving surgery without radiation therapy.
- Clinical trials testing breast-conserving surgery and tamoxifen with or without radiation therapy.
Check for U.S. clinical trials from NCI’s list of cancer clinical trials that are now accepting patients with ductal breast carcinoma in situ. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. General information about clinical trials is available from the NCI Web site.
Lobular Carcinoma In Situ (LCIS)
Treatment of lobular carcinoma in situ (LCIS) may include the following:
- Biopsy to diagnose the LCIS followed by regular examinations and regular mammograms to find any changes as early as possible. This is called observation.
- Tamoxifen to reduce the risk of developing breast cancer.
- Bilateral prophylactic mastectomy. This treatment choice is sometimes used in women who have a high risk of getting breast cancer. Most surgeons believe that this is a more aggressive treatment than is needed.
- Clinical trials testing cancer prevention drugs.
