Ductal carcinoma in situ or DCISDuctal carcinoma in-situ is the most common type of non-invasive breast tumor. It is characterized by abnormal cells that are confined in the milk ducts. They are not malignant but they may turn cancerous. In fact, it is usually called as stage 0 breast cancer. Symptoms such as lumps don't usually appear. It is only discovered if you undergo mammography.
Will ductal carcinoma in-situ develop into a full-blown invasive ductal carcinoma? Most DCIS cases don't even without treatment. But DCIS is a risk factor for any of the invasive ductal carcinoma types. If left untreated and unchecked, it can become aggressive. That's why some doctors recommend treatment.
How is ductal breast cancer in-situ treated? Surgery is usually recommended to remove the abnormal cells. You may choose between lumpectomy or mastectomy. If you decide on lumpectomy, your doctor will prescribe radiation after your surgery. This is to ensure that abnormal cells missed by surgery will be destroyed.
