What is an Intraductal Papilloma?

Intraductal papillomas are benign (non-cancerous), wart-like tumors that grow within the milk ducts of the breast.

They are made up of gland tissue along with fibrous tissue and blood vessels (called fibrovascular tissue).

This is not related to or caused by human papilloma virus.

Solitary papillomas (solitary intraductal papillomas) are single tumors that often grow in the large milk ducts near the nipple. They are common cause of clear or bloody nipple discharge, especially when it comes from only one breast.

They may be felt as a small lump behind or next to the nipple. Sometimes they cause pain.

The papilloma is typically a small, tan-pink growth - usually less than one centimeter (cm) - although it can grow up to five or six cm. It usually occurs in women between the ages of 30 and 50. Sometimes it is picked up on a screening mammogram or via ultrasound.

Papillomas may also be found in small ducts in areas of the breast farther from the nipple. In this case, there are often several growths (multiple papillomas). These are less likely to cause nipple discharge.

In papillomatosis, there are very small areas of cell growth within the ducts, but they aren’t as distinct as papillomas are.

Under a microscope, a papilloma appears to be made up of finger-like projections.

How Do I Prevent Intraductal Papilloma?

There’s no specific way to prevent intraductal papilloma. However, you can increase the likelihood of early detection by seeing your doctor regularly for breast exams, doing monthly breast self-exams, and having regular screening mammograms. You should also call your doctor if you have concerns about anything related to your breast health.

Surgical Removal of a Papilloma

Your doctor will perform minor surgery to remove the papilloma itself or the duct with the papilloma inside it. Often a small cut can be made along the circular edge of the areola (the darker skin surrounding the nipple). A pathologist (a doctor who examines cell samples) can then examine the papilloma to make sure all of the cells are normal, confirming you are at no increased risk of breast cancer.

Depending on the surgical pathology of your papilloma, you may need further follow ups to monitor your breast. Your doctor will discuss the options after your pathology results are back.
