What is the survival rate of invasive ductal carcinoma? The five-year survival rate for localized invasive ductal carcinoma is high — nearly 100% when treated early on. If the cancer has spread to other tissues in the region, the five-year survival rate is 86%. If the cancer has metastasized to distant areas of your body, the five-year survival rate is 28%.
How serious is milk duct cancer? Ductal carcinoma in situ (DCIS) is the earliest possible form of breast cancer. It needs to be treated but is not life-threatening. Breast cancer usually starts in the cells that line the lobules and the milk ducts that carry milk from the lobule out through the nipple.
Why does breast cancer start in the milk ducts? DCIS forms when genetic mutations occur in the DNA of breast duct cells. The genetic mutations cause the cells to appear abnormal, but the cells don’t yet have the ability to break out of the breast duct. Researchers don’t know exactly what triggers the abnormal cell growth that leads to DCIS.
Can you get cancer in your milk ducts? 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 is considered non-invasive or pre-invasive breast cancer.
