Breast Cancer In Milk Ducts Stage 2

Invasive ductal carcinoma idc sometimes called infiltrating ductal carcinoma is the most common type of breast cancer.

Breast cancer in milk ducts stage 2.

Invasive ductal carcinoma begins in the breast s milk ducts and invades surrounding breast tissue. Dcis is noninvasive meaning it hasn t spread out of the milk duct and has a low risk of becoming invasive. Idc is the most common form of breast cancer representing 80 percent of all breast cancer diagnoses. Ductal carcinoma in situ dcis is non invasive breast cancer.

There are two types. Dcis ductal carcinoma in situ is a non invasive breast cancer. Over time the cancer can spread to nearby lymph nodes and other tissues. Like other types of invasive ductal cancer mucinous ductal carcinoma begins in the milk duct of the breast before spreading to the tissues around the duct.

It s called in situ which means in place because the cells have not left the milk ducts to invade nearby breast tissue. Ductal carcinoma in situ dcis is the presence of abnormal cells inside a milk duct in the breast. The type of tissue where your breast cancer arises determines how the cancer behaves and what treatments are most effective. In dcis the abnormal cells are contained in the milk ducts canals that carry milk from the lobules to the nipple openings during breastfeeding.

Microscopic evaluations reveal that these cancer cells are surrounded by mucus. About 80 of all breast cancers are invasive ductal carcinomas. This type of cancer forms in the lining of a milk duct within your breast. Dcis is considered non invasive or pre invasive breast cancer.
