What Is Paget's Disease of the Nipple?

Breast cancer ribbonPaget’s disease, also called Paget’s disease of the nipple or mammary Paget’s disease (not to be confused with Paget's disease of the bone), is a rare form of breast cancer that accounts for about 1% of all breast cancer cases. Paget’s disease affects the nipple and often spreads to the areola. Patients diagnosed with Paget’s disease are usually found to have tumors in the same breast—either ductal carcinoma in situ or invasive breast cancer.

 

Causes

While the causes of Paget’s disease are not well understood, a widely accepted theory is that cells from a cancer elsewhere in the breast travel through the milk ducts and begin to affect the nipple. This would explain why additional cancers are frequently found in Paget’s disease patients. However, because additional tumors are not always found, it is also possible that the cells of the nipple become cancerous on their own.

 

Symptoms

Paget’s disease may cause the following symptoms:

  • Flaky, crusty, red, or thickened skin around the nipple or areola
  • Burning, tingling, or itching
  • Pain or heightened sensitivity
  • Flattened or inverted nipple
  • Yellowish or bloody nipple discharge

Because Paget’s disease is relatively rare, some symptoms are often mistaken for symptoms of more common skin ailments like eczema or dermatitis.

 

Diagnosis

If Paget’s disease is suspected, many doctors will begin by performing a physical exam. This can help to identify other palpable cancers, which exist in as many as 50% of patients with Paget’s disease. You will then likely undergo a mammogram, which a radiologist will examine for evidence of cancer in the nipple and elsewhere in the breast. Additional MRI or ultrasound imaging may also be ordered. To diagnose Paget’s disease, a biopsy will be taken of the nipple. This can take a few different forms, from a surface biopsy, which involves the scraping of cells from the nipple’s surface, to procedures that take larger amounts of tissue. Ask your doctor about any questions you have about the biopsy that’s ordered for you.

 

Treatment

Depending on the extent of the cancer, the presence or absence of additional cancers, and lymph node involvement, the treatment for Paget’s disease can range from breast-conserving surgery, which includes removal of the nipple and areola followed by radiation treatment, to mastectomy. After mastectomy, radiation treatment, chemotherapy, and/or hormone therapy may also be recommended.

 

Prognosis

The prognosis for Paget’s disease patients depends largely on whether an additional palpable breast tumor is present. Among patients with no palpable tumor prior to surgery, the survival rate is very high—reported at 92–94% at 5 years and 82–91% at 10 years. The presence identifiable underlying tumors has a significant impact on prognosis, however, with patients surviving five years at a rate of 38–40% and 22–33% surviving 10 years. As with any type of breast cancer, early detection, prompt treatment, and healthy habits are the keys to having the best possible chance of long-term survival.
