The evaluation of intraductal papilloma begins with a history and physical examination.

Physical findings in a woman with intraductal papilloma may include:

• Breast lump:
• Often a lump is found by a woman during self-examination
• Breast dimpling:
• A dimple in the skin over the breast
• Nipple discharge

Tests are required to make the diagnosis of intraductal papilloma.

Tests that may be used to evaluate intraductal papilloma include:

• Breast ultrasound:
• Can see if a lump is solid or cystic
• Mammography:
• Often the first test used to evaluate the breast
• Miraluma scan:
• A nuclear test that may be better for women with dense breasts
• Breast biopsy:
• Tissue is removed with a needle or surgery
• Breast MRI
