ductal carcinoma in situ of breast

DCIS

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.

Treatment

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
