What is ductal carcinoma in situ (DCIS)?
Ductal carcinoma in situ (DCIS) is the earliest form of breast cancer. It is abnormal cells found within the lining of the breast milk ducts that have not yet spread. However, DCIS has the potential to spread by growing through the milk duct walls. DCIS is often discovered during a routine mammogram.

What are some of the signs?
DCIS is identified as tiny groups of calcium deposits generally detected on a routine mammogram. Most women do not experience any signs or symptoms. However, DCIS is on some occasions associated with a breast mass. Once DCIS is detected, the diagnosis is confirmed with a breast biopsy, which provides information about the tumor cells and hormone status.

Can DCIS be treated? 
Yes, various treatment options are available. Schedule an appointment with our oncology team today to discuss the option best for you.

What is life after DCIS?
After completion of treatment, you will begin follow-up care with your oncologist to ensure your continued good health. Mammogram screening will also be a part of this care. The diagnosis and treatment of DCIS can have a considerable emotional impact. It is important to discuss your concerns and feelings about your diagnosis and treatment with your oncology care team. We recommend you maintain a balanced diet and a healthy body weight and limit alcohol consumption. We also recommend that you avoid estrogen replacement therapy for menopausal symptoms. These modifiable risk factors are important in reducing your risks of breast cancer in the future.
