ductal carcinoma in situ of breast



A cluster of malignant cells in the mammary ducts that has not spread to surrounding breast tissue. It is the most common noninvasive breast cancer and accounts for 25% of all breast cancer diagnoses. If left untreated, as many as 50% of patients with DCIS will develop invasive cancer. Because these cells grow in the ducts, they develop without forming a palpable mass. In its early stage this condition can be diagnosed through the use of mammography.


Lumpectomy is the most common treatment, followed by radiation. Mastectomy may be recommended if multiple areas are found or if there is a strong family history of breast cancer.

Synonym: comedocarcinoma See: breast cancer; mammography

Patient discussion about DCIS

Q. Hi all. I was diagnosed with DCIS in April. Had a lumpectomy about 3 cm and it was removed. Am I cured fully? Hi all. I was diagnosed with DCIS in April. Had a lumpectomy about 3 cm and it was removed. I then had 28 radiation and 4 boosters. I went to the cancer center for my checkup and the doctor said nothing to worry. They didn’t advice me further follow up and I am normal for the past 6 months and not even taking tamoxifen. I am quite normal like others. Am I cured fully?

A. Hey nothing to worry!! Early diagnosis is half cured. The same thing applies to your case. With early diagnosis and treatment, the doctors should have removed the cancer parts with the surgery. Based on the report they have given you radiation and other meds. If you be estrogen +ve then they would have given you it as a preventive. By the way if you have any doubts better approach your doctor and have your checkup done as a precautionary measure.

Q. My wife is diagnosed with DCIS type of breast cancer. My wife is diagnosed with DCIS type of breast cancer. Doctors had staged my wife`s cancer as low. She is still due for some tests which she will soon have. Doctor have told that there is nothing much to worry so why are they taking so many tests?

A. All the tests are taken to confirm about the type of treatment to be given. These pre treatment tests can avoid the risk of post treatment complications. Even if the complications arise they will know the best possible course of counter treatment. So please cooperate with the doctor.
