Invasive ductal carcinoma accounts for 80 percent of all diagnosed breast cancer. At the Abramson Cancer Center, we offer comprehensive care that includes expertise, innovation and support for every stage of invasive ductal carcinoma and other infiltrating breast cancer types.
What Is Invasive Ductal Carcinoma (IDC)?
Invasive ductal carcinoma (IDC), also known as infiltrating ductal carcinoma, is a type of breast cancer that starts in the milk ducts of the breast and moves into nearby tissue. In time, IDC may spread (metastasize) through the lymph nodes or bloodstream to other areas of the body. This is known as metastatic breast cancer. Invasive ductal carcinoma is also the most common type of male breast cancer.
Rare Subtypes of IDC Breast Cancer
Some people may be diagnosed with a subtype of IDC. These diagnoses are rare, with each one making up less than 5 percent of all breast cancers. Less common forms of IDC include:
- Medullary carcinoma
- Metaplastic carcinoma
- Mucinous (or colloid) carcinoma
- Papillary carcinoma
- Tubular carcinoma
Invasive Ductal Carcinoma Symptoms
IDC may be discovered on a mammogram before presenting any symptoms. However, some individuals may have symptoms including:
- Changes in breast shape
- Breast or nipple pain
- Discharge from the nipple
- Swelling of the breast
- A lump in the breast tissue
- Thickening of the nipple skin
Diagnosing Infiltrating Ductal Carcinoma
IDC is typically diagnosed after detection through routine breast cancer screenings such as mammogram. While IDC does not always produce typical breast cancer symptoms, you may notice a new lump or unusual changes in your breast. If your physician suspects breast cancer, additional tests and a breast biopsy may confirm a diagnosis of IDC. The size of the initial tumor and the extent of cancer spread determines the stage of breast cancer.

How Invasive Ductal Carcinoma Is Staged
Invasive ductal carcinoma (IDC) can be described as a stage 1 (earliest stage) to a stage IV (most advanced stage), depending on the size of the tumor and how far it has spread.

What Is the Prognosis for IDC?
When caught and treated early, the prognosis for localized invasive ductal carcinoma is good with a 5-year survival rate of nearly 100%. If the cancer has spread to nearby tissue or metastasized to other areas of the body the 5-year survival rate drops. Your healthcare provider will be able to discuss your individual prognosis and treatment options with you.
Treatment for Infiltrating Ductal Carcinoma
The first step in personalized and effective IDC breast cancer treatment is an accurate diagnosis. Our specialized breast cancer pathologists and radiologists work together to get an accurate diagnosis, including hormone receptors and HER2 status. With this information in hand, we tailor your breast cancer treatment.
The IDC treatment your physician decides is best for you relies on many factors, such as stage, size of tumor, spread of the cancer cells, and your personal health. Because invasive ductal carcinoma can be diagnosed as stage I through IV, there are several different treatments that may be used and used in varying combinations:
