Ductal carcinoma in situ (Stage 0) is the most common non-invasive breast cancer, where abnormal cells have been contained in the lining of the breast milk duct.

Invasive ductal carcinoma, the most common type of breast cancer, occurs when mutated cells spread from the milk ducts into the breast tissue. It can also metastasize and affect other parts of the body if left untreated.

Symptoms of Ductal Carcinoma

There are warning signs that could be symptoms of ductal carcinoma:

  • Red, swollen, dimpled, or puckered skin on the breast, nipple, or areola

If you notice any of these symptoms, make an appointment with your doctor.
