What is indicated by a T1 stage in breast cancer?

• A. Tumor larger than 5 cm
• B. Tumor smaller than or equal to 2 cm
• C. Tumor between 2 cm and 5 cm
• D. Tumor invading chest wall or skin

Answer: (B)

A T1 stage in breast cancer specifically indicates that the tumor is smaller than or equal to 2 cm in greatest dimension. This classification is part of the TNM staging system, which helps determine the extent of cancer. T1 signifies an early stage where the cancer is still localized and has not spread significantly. In the context of breast cancer, this small size often correlates with a better prognosis and more treatment options, as the cancer is detected while it is still relatively contained. Understanding this stage can help inform treatment strategies and patient management, as earlier detection generally leads to improved outcomes. The other size classifications refer to larger tumors or cases where the cancer has spread, which would indicate a more advanced stage and potentially different treatment considerations.
