In TNM staging, which term describes a larger primary tumor that may invade nearby tissue?

• A. T0
• B. T2
• C. N2
• D. M0

Answer: (B)

In TNM staging, the T category describes the size and local extent of the primary tumor. As the tumor grows larger and can invade nearby tissues, the T designation becomes higher. The description “a larger primary tumor that may invade nearby tissue” points to that higher T category, which reflects greater size and local invasion. The N category, in contrast, refers to regional lymph node involvement, and the M category to distant metastasis. Since the statement focuses on the primary tumor’s size and its potential to invade surrounding areas, the best match is the higher T category.
