What is the typical age range for patients diagnosed with intraductal papilloma?

Intraductal papilloma is a benign breast lesion that is most commonly diagnosed in women between the ages of 30 and 50 years. This range corresponds with the answer provided, which places the typical age group at 30-40 years.

The formation of intraductal papillomas is associated with hormonal changes that occur during the reproductive years, making it less common in women who are under 20, or those who are beyond their reproductive years, such as those over 70. The growth of breast tissue and the potential for the development of various types of lesions, including intraductal papillomas, tapers off significantly after menopause, which is why older age groups see a steep decline in these diagnoses. Thus, the 30-40 years range represents the peak development period for these lesions.
