There are many forms of breast cancer. One form is papillary carcinoma, which is characterized by its unique finger-like growths within the breast milk ducts.

At Aurora Health Care, we're dedicated to providing comprehensive information and personalized care to help you navigate your diagnosis with confidence and clarity. We offer the latest cancer care technology, including genetic counseling to better determine your risk and a range of diagnostic tools to accurately diagnose papillary carcinoma breast cancer.

What is a papillary carcinoma?

Papillary carcinoma of the breast can be a noncancerous or cancerous tumor found in the milk duct near the nipple. It can be invasive or in situ.

Papillary carcinoma breast cancer starts in the milk ducts. It’s a rare and unique form that is characterized by finger-like projections. It can occur in one or both breasts and is often discovered during routine mammograms or when you notice changes in your breast tissue in a self-exam.

Papillary carcinoma breast cancer can appear in two forms: invasive and in situ. Invasive papillary carcinoma spreads beyond the ducts, while in situ remains confined.

This form of breast cancer is more common in postmenopausal women and can be benign (noncancerous) or malignant (cancer).

Types of papillary carcinoma

  • Encapsulated papillary carcinoma: Typically confined within a thick fibrous capsule in the breast ducts and is less likely to spread.
  • Solid papillary carcinoma: Forms solid masses in the breast ducts and can be either benign or malignant.
  • Invasive papillary carcinoma: Starts in the breast ducts and spreads to surrounding tissues.

Is papillary breast cancer aggressive?

Generally, papillary breast cancer is considered less aggressive compared to other types of breast cancer. However, invasive papillary carcinoma has the potential to spread beyond the original site, so it’s considered more aggressive. It's also crucial to diagnose whether the papillary carcinoma is invasive or in situ to understand the potential aggressiveness of the disease.

Risk factors for papillary carcinoma

  • Age: Most common in postmenopausal women between the ages of 45 and 55.
  • Family history: A family history of breast cancer can elevate your risk.
  • Genetic mutations: Certain genetic factors such as BRCA1 and BRCA2 gene mutations that are passed down from a parent can increase your risk.
  • Hormonal factors: Hormone replacement therapy post-menopause can increase your risk.

Recognizing these risk factors can help in early detection and prevention strategies.

Papillary carcinoma symptoms

Symptoms of papillary carcinoma can be subtle and vary for every person. Common signs to watch for include:

  • Breast lumps: Noticeable lumps that feel different from the surrounding tissue.
  • Nipple discharge: Unusual discharge, which may be clear or bloody.
  • Breast changes: Alterations in the size, shape or appearance of the breast.
  • Skin changes: Dimpling or changes in skin texture over the breast.

Regular self-exams and mammograms are essential for early detection.

Papillary carcinoma diagnosis

Diagnosing papillary carcinoma breast cancer usually involves a combination of imaging tests and biopsies.

A mammogram is often the first step as it can reveal lumps or abnormalities in your breast tissue. If a mammogram indicates an abnormality, an ultrasound provides a clearer picture, helping to determine if the lump is solid or filled with fluid.

To confirm papillary carcinoma, your doctor will perform a biopsy. This involves taking a small tissue sample from the lump for microscopic examination. Types of biopsies include core needle biopsy and excisional biopsy, depending on the carcinoma’s characteristics.

Once a diagnosis is confirmed, your provider will discuss the appropriate treatment options with you.

Papillary carcinoma treatment

Treatment options for papillary carcinoma vary based on the type and stage of your cancer. Common treatments include:

  • Surgery: Lumpectomy or mastectomy to remove cancerous tissue.
  • Radiation therapy: Targets and kills cancer cells remaining post-surgery.
  • Hormone therapy: For hormone receptor-positive cancers, to slow or stop cancer growth.
  • Chemotherapy: Uses drugs to destroy cancer cells, typically for invasive types.

At Aurora, your care team will use a collaborative approach to deliver the best treatment for you. We also offer a variety of supportive care services, including counseling, nutrition therapy, palliative care and physical therapy.

What is the prognosis of papillary carcinoma?

The prognosis for papillary carcinoma is generally favorable, especially when detected early. In situ types have a better prognosis with appropriate treatment.

Invasive papillary carcinoma can also have a good outcome with timely and effective treatment. Regular follow-ups and monitoring are essential to manage and detect any cancer recurrence early.

Are you at risk for breast cancer?

Knowing your chance of developing breast cancer can help you plan a routine screening schedule. Our breast health quiz estimates your five-year and lifetime risk and gives you an idea of what to do next based on your results.
