Parts of the breast where cancer begins include.
Stage 1 breast cancer in milk duct.
Ductal carcinoma in situ dcis is the presence of abnormal cells inside a milk duct in the breast.
Invasive ductal carcinoma idc also known as infiltrating ductal carcinoma is cancer that began growing in a milk duct and has invaded the fibrous or fatty tissue of the breast outside of the duct.
Ductal carcinoma in situ dcis means the cells that line the milk ducts of the breast have become cancer but they have not spread into surrounding breast tissue.
Dcis ductal carcinoma in situ is a non invasive breast cancer.
Dcis is considered the earliest form of breast cancer.
Invasive ductal carcinoma idc.
In stage 0 breast cancer the atypical cells have not spread outside of the ducts or lobules into the surrounding breast tissue.
Ductal carcinoma is a common type of breast cancer that starts in cells that line the milk ducts which carry breast milk to the nipple.
Ductal carcinoma is the most common type of breast cancer.
This type of cancer forms in the lining of a milk duct within your breast.
In dcis the abnormal cells are contained in the milk ducts canals that carry milk from the lobules to the nipple openings during breastfeeding.
The type of tissue where your breast cancer arises determines how the cancer behaves and what treatments are most effective.
There are two types.
But those cells have not spread beyond the wall of the duct to reach.
It s called in situ which means in place because the cells have not left the milk ducts to invade nearby breast tissue.
Stage 0 breast cancer or ductal carcinoma in situ dcis is when there are abnormal cells in the lining of the milk ducts.
Dcis is noninvasive meaning it hasn t spread out of the milk duct and has a low risk of becoming invasive.
