Final answer:
Purulent nipple discharge is typically associated with a breast abscess. Although other conditions like intraductal papilloma, fibrocystic changes, and breast cancer can cause nipple discharge, pus indicates infection that is characteristic of an abscess.
Step-by-step explanation:
Purulent nipple discharge is commonly associated with a breast abscess, which is a condition that occurs when an area of the breast tissue becomes infected, leading to the formation of a pus-filled lump. While intraductal papilloma, fibrocystic changes, and breast cancer can also cause nipple discharge, the characteristic of being purulent, or containing pus, points more towards an abscess. It is essential for an individual to seek medical attention if they experience purulent nipple discharge, as this may require prompt diagnosis and treatment to prevent further complications. Additionally, uncommon changes like unusual bleeding or discharge, lump in the breast, chronic indigestion or difficulty swallowing, obvious changes in a wart or mole, and persistent coughing or hoarseness can be signs of serious conditions such as cancer and should be evaluated by a healthcare professional.
