Ductal carcinoma in situ DCIS is non-invasive breast cancer. Ductal means that the cancer starts inside the milk ducts, carcinoma refers to any cancer that begins in the skin or other tissues including breast tissue that cover or line the internal organs, and in situ means "in its original place. When you have had DCIS, you are at higher risk for the cancer coming back or for developing a new breast cancer than a person who has never had breast cancer before.
Ductal carcinoma in situ DCIS means the cells that line the milk ducts of the breast have become cancerbut they have not spread into surrounding breast tissue. DCIS is considered non-invasive or pre-invasive breast cancer. But sometimes a mastectomy might be a better option.
Most women diagnosed with this noninvasive breast cancer are alive 10 years later, and better treatments are emerging. For the 62, women who will be diagnosed with ductal carcinoma in situ DCIS this year, the good news is far more important than the bad. While cancer is never a picnic, DCIS is the earliest detectable form of the disease.
The stage of cancer indicates the size of the tumor of abnormal cells and whether or not those cells are contained to the place of origin. The most common type of breast cancer is ductal carcinoma in situ DCISindicating the cancer cell growth starts in the milk ducts. Stage 0 breast cancer,ductal carcinoma in situ DCIS is a non-invasive cancer where abnormal cells have been found in the lining of the breast milk duct.
Ductal carcinoma in situ DCIS of the breast represents a complex, heterogeneous pathologic condition in which malignant epithelial cells are confined within the ducts of the breast without evidence of invasion. As the incidence of DCIS increases, the treatment options continue to evolve. Consistent pathologic evaluation is crucial in optimizing treatment recommendations.
Despite the fact that its name includes the term "carcinoma," LCIS is not a true breast cancer. Rather, LCIS is an indication that a person is at higher-than-average risk for getting breast cancer at some point in the future. LCIS is restricted to the lobules.
Ductal carcinoma in situ DCISalso known as intraductal carcinomais a pre-cancerous or non-invasive cancerous lesion of the breast. In DCIS, abnormal cells are found in the lining of one or more milk ducts in the breast. In situ means "in place" and refers to the fact that the abnormal cells have not moved out of the mammary duct and into any of the surrounding tissues in the breast "pre-cancerous" refers to the fact that it has not yet become an invasive cancer.
DCIS is a very early stage of breast cancer in which the abnormal cells are confined to the lining of breast ducts. If not treated, some cases of DCIS cases will progress to invasive cancer. LCIS, in contrast, is not believed to be a direct cancer precursor, but does indicate that a woman is at increased risk of developing breast cancer. The role of early treatment is less clear for patients with LCIS.
DCIS means that some cells in the lining of the ducts of the breast tissue have started to turn into cancer cells. These cells are all contained inside the ducts. They have not started to spread into the surrounding breast tissue.
Ductal carcinoma in situ DCIS of the breast is a potentially invasive neoplasm. Risk factors include high estrogen states such as use of oral contraceptive OC pills, nulliparity, advanced age at first birth, and also family history and genetic mutations. The incidence of this usually clinically silent condition has risen in the past few decades due to widespread screening and diagnostic mammography, with final diagnosis confirmed by biopsy. At present, treatment options include total or simple mastectomy or lumpectomy with radiation.
