Which characteristic is most likely associated with lobular carcinoma in situ (LCIS)?

• A. It typically progresses to invasive cancer
• B. It represents a benign condition with no risk for cancer
• C. It is a premalignant change that indicates high risk for breast cancer development
• D. It can be completely cured with medication

Answer: (C)

Lobular carcinoma in situ (LCIS) is recognized as a marker for an increased risk of developing breast cancer in the future. While LCIS itself is not considered a true breast cancer and is classified as a non-invasive condition, its presence is significant as it indicates a higher likelihood of subsequent invasive breast cancer, particularly in either breast. This characteristic aligns with the understanding of LCIS as a premalignant change rather than a benign condition. It is important to differentiate this from other conditions. For example, the idea that LCIS typically progresses to invasive cancer is not accurate; many individuals with LCIS may never develop invasive cancer. Additionally, LCIS itself is not a benign condition in the sense that it presents no risk for future cancer; hence, stating it represents a benign condition with no risk for cancer is misleading. The notion that it can be completely cured with medication does not reflect the current understanding of LCIS, as treatment typically involves monitoring rather than a definitive curative approach like medication would suggest. This understanding reinforces why recognizing LCIS as an indicator of high risk for future breast cancer development is crucial for patient management and screening.
