What Is DCIS?
Ductal carcinoma in situ (DCIS) is an early form of cancer confined to the lactiferous (milk producing) ducts of the breast.
DCIS Treatment Options
The choice of whether surgery is required or what surgery is best for you can be a difficult decision to make. After reviewing your diagnosis in clinic, the breast surgeon can work with you to arrive at a shared decision that balances your peace of mind, your cosmetic expectations as well as the treatment for your breast cancer.
Is DCIS Cancer?
DCIS is sometimes referred to as "pre-cancer" or "stage 0" breast cancer. A DCIS diagnosis indicates that cancerous cells were found inside the lactiferous ducts of the breast, usually during a routine mammogram, but have not spread. The cells can develop into cancer if left untreated.
