The key difference between screening and diagnostic mammography lies in the purpose and context in which each is performed. Screening mammography is designed for asymptomatic women to detect breast cancer before any symptoms appear. It aims to identify issues in the breast tissue early on, which can be crucial for effective treatment.

In contrast, diagnostic mammography is performed when there are specific signs, symptoms, or abnormalities that need to be explored further. This could involve the investigation of a palpable lump, unusual changes seen in a previous mammogram, or any other symptoms such as discharge from the nipple or changes in breast size or shape. The focus of diagnostic mammography is to provide additional imaging to clarify the nature of these findings.

The other options do not accurately represent this distinction. While screening does involve individuals who are generally asymptomatic, stating that it is meant for symptomatic individuals is incorrect. Similarly, stating that diagnostic mammography is conducted for asymptomatic individuals mischaracterizes its purpose. Screening does not necessarily require a physician’s order, as it can often be scheduled as part of routine health care without a direct referral. Thus, option C clearly identifies diagnostic mammography as the method used to investigate specific issues, setting it apart from screening practices.
