In cancer staging, which term indicates distant metastasis is present?

• A. M1
• B. M0
• C. N3
• D. T2

Answer: (A)

In cancer staging, the M category stands for metastasis, which is the spread of cancer to distant sites. A designation of M1 means there is distant metastasis present, signaling that the cancer has spread beyond the original region to distant organs or tissues. By contrast, M0 means no distant metastasis. The other terms, N3 and T2, relate to regional lymph node involvement and the size/extent of the primary tumor, respectively, and do not indicate distant spread. Recognizing M1 is important because it often influences treatment decisions toward systemic therapies and informs prognosis.
